// If you want to select multiple elements via a css selector, then you must use the multiple function. Under the hood QuerySelectorAll is used.
[anElement1, anElement2] = AutoNumeric.multiple('.myCssClass > input', { options }); // This always return an Array, even if there is only one element selected
[anElement1, anElement2] = AutoNumeric.multiple('.myCssClass > input', [null, 12345.789], { options }); // Idem above, but with passing the initial values too
`

Note: Using an array of option objects / pre-defined names will always merge those settings. The resulting setting objet will then be applied to all the selected elements ; they will share the exact same settings.

For instance when using { 0: '-' }, the hyphen '-' is displayed when the rawValue is equal to 0. Multiple 'replacements' can be defined. | null |
| watchExternalChanges | Defines if the AutoNumeric element should watch (and format) external changes made without using .set(). This is set to false by default to prevent infinite loops when used with third party frameworks that relies on the 'autoNumeric:rawValueModified' events being sent. | false |
| wheelOn | Used in conjonction with the modifyValueOnWheel option, defines when the wheel event will increment or decrement the element value, either when the element is focused, or hovered | 'focus' |
| wheelStep | Used in conjonction with the modifyValueOnWheel option, this allow to either define a fixed step (ie. 1000), or a progressive one that is calculated based on the size of the current value | 'progressive' |

#### Predefined options

Sometimes you do not want to have to configure every single aspect of your format, specially if it's a common one.
Hence, we provide multiple default options for the most common currencies and number formats.

##### Predefined language options

autoNumeric provides predefined language options to format currencies.

You can set the pre-defined language option like so:
`js
// Use the methods
new AutoNumeric('.mySelector > input').french();
// ...or just create the AutoNumeric object with the language option
new AutoNumeric('.mySelector > input', AutoNumeric.getPredefinedOptions().French);
`

Currently, the predefined language options are:

| | Option name |
| :---------------- | :---------------- |
| :fr: | French |
| :es: | Spanish |
| :us: | NorthAmerican |
| :uk: | British |
| 🇨🇭 | Swiss |
| :jp: | Japanese |
| :cn: | Chinese |
| 🇧🇷 | Brazilian |
| :tr: | Turkish |

If you feel a common currency option is missing, please create a pull request and we'll add it!

##### Predefined common options

You can set those pre-defined options like so:
`js
new AutoNumeric('.mySelector > input', AutoNumeric.getPredefinedOptions().integerPos);
`

##### Predefined style rules

With the styleRules option, you can define the rules that add or remove the CSS class(es) from the element, based on the raw unformatted value.
This option can also be used to define custom callbacks in the userDefined attribute, that will be called whenever the rawValue is updated.

Predefined styles are available so you do not have to create them:

###### Positive and negative
Sets the 'autoNumeric-positive' css class whenever the raw value is positive.

Sets the 'autoNumeric-negative' css class whenever the raw value is negative.
`js
new AutoNumeric(domElement, { styleRules: AutoNumeric.options.styleRules.positiveNegative });
`

###### Range from 0 to 100, in 4 steps
Sets the 'autoNumeric-red' css class whenever the raw value is between 0 and 25 excluded.

Sets the 'autoNumeric-orange' css class whenever the raw value is between 25 and 50 excluded.

Sets the 'autoNumeric-yellow' css class whenever the raw value is between 50 and 75 excluded.

Sets the 'autoNumeric-green' css class whenever the raw value is between 75 and 100 excluded.
`js
new AutoNumeric(domElement, { styleRules: AutoNumeric.options.styleRules.range0To100With4Steps });
`

###### Odd and even
Sets the 'autoNumeric-even' css class whenever the raw value is even.

Sets the 'autoNumeric-odd' css class whenever the raw value is odd.
`js
new AutoNumeric(domElement, { styleRules: AutoNumeric.options.styleRules.evenOdd });
`

###### Small range around zero, from -1 to 1
Sets the 'autoNumeric-small-negative' css class whenever the raw value is between -1 and 0 excluded.

Sets the 'autoNumeric-zero' css class whenever the raw value is equal to 0.

Sets the 'autoNumeric-small-positive' css class whenever the raw value is between 0 excluded and 1.
`js
new AutoNumeric(domElement, { styleRules: AutoNumeric.options.styleRules.rangeSmallAndZero });
`

###### Custom callbacks
Custom callbacks can be defined and will be called every time the raw value is updated.

You can add as many callbacks you want in the userDefined attribute of the styleRules object in the options.

Each userDefined array entry should at least provide a function as the callback attribute.

This callback function is passed the rawValue as the single parameter (except if classes is null or undefined, see below).

Depending of what type of data the callback function returns, and what the content of the classes attribute is, it will either uses CSS class names defined in the classes attribute, or just call the callback with the current AutoNumeric object passed as a parameter if classes is null or undefined.

| # | Callback return type | classes content | Result |
| :----------------: | :----------------: | :-----------: | :-----------: |
| 1 | a boolean | a single String | If true, add the single class defined in classes. If false removes it. |
| 2 | a boolean | an Array with 2 values (array indexes) | If true, add the first element of the array, otherwise the second |
| 3 | an integer | an Array with multiple values (array indexes) | Will add the selected CSS class classes[index], and remove the others |
| 4 | an Array of integer | an Array with multiple values (array indexes) | Will add all the given selected CSS classes, and remove the others |
| 5 | ∅ | null or undefined | There, the callback have access to the current AutoNumeric object passed as its argument, which means you are free to do whatever you want from here! |

See the following examples:
`js
const options = {
styleRules : {
userDefined: [
// 1) If 'classes' is a string, set it if true, remove it if false
{ callback: rawValue => { return true; }, classes: 'thisIsTrue' },
// 2) If 'classes' is an array with only 2 elements, set the first class if true, the second if false
{ callback: rawValue => rawValue % 2 === 0, classes: ['autoNumeric-even', 'autoNumeric-odd'] },
// 3) Return only one index to use on the classes array (here, 'class3')
{ callback: rawValue => { return 2; }, classes: ['class1', 'class2', 'class3'] },
// 4) Return an array of indexes to use on the classes array (here, 'class1' and 'class3')
{ callback: rawValue => { return [0, 2]; }, classes: ['class1', 'class2', 'class3'] },
// 5) If 'classes' is undefined or null, then the callback is called with the AutoNumeric object passed as a parameter
{ callback: anElement => { return anElement.getFormatted(); } },
],
},
}
`

#### Special options

###### noEventListeners
Using the noEventListeners option allow autoNumeric to only format without adding any event listeners to an input, or any other DOM elements (that the function would accept as a parameter). This would be useful for read-only values for instance.
`js
// Initialize without setting up any event listeners
anElement = new AutoNumeric(domElement, 12345.789, { options }).remove(); // This is the default existing way of doing that...
// ...but you can also directly pass a special option noEventListeners to prevent the initial creation of those event listeners
anElement = new AutoNumeric(domElement, 12345.789, { noEventListeners: true });
`
In the latter case, it initialize the AutoNumeric element, except it does not add any event listeners. Which means it format the value only once and then let the user modify it freely.
Note: The value can then be formatted via a call to set.

###### readOnly
AutoNumeric can initialize an element with the readonly property by setting the readOnly option to true in the settings:
`js
anElement = new AutoNumeric(domElement, 12345.789, { readOnly: true });
`

For more detail on how to use each options, please take a look at the detailed comments in the source code for the defaultSettings object.

#### Options update
Options can be added and/or modified after the initialization has been done.

Either by passing an option object that contains multiple options,
`js
anElement.update({ moreOptions });
anElement.update(AutoNumeric.getPredefinedOptions().NorthAmerican); // Update the settings (and immediately reformat the element accordingly)
`

by passing multiple option objects, the latter overwriting the settings from the former ones...
`js
anElement.update({ moreOptions1 }, { moreOptions2 }, 'euro');
// or in a single array
anElement.update([{ moreOptions1 }, { moreOptions2 }, 'euro']);
`

...or by changing the options one by one (or by calling a pre-defined option object).
`js
anElement.options.minimumValue('12343567.89');
anElement.options.allowDecimalPadding(false);
`

At any point, you can reset the options by calling the options.reset() method.
This effectively drop any previous options you could have set, then load back the default settings.
`js
anElement.options.reset();
`

Lastly, the option object can be accessed directly, thus allowing to query each options globally too
`js
anElement.getSettings(); // Return the options object containing all the current autoNumeric settings in effect
`

Methods

First. you need to get a reference to the AutoNumeric module that you need to import:
`js
import AutoNumeric from 'autonumeric';
`

Then you'll be able to access either the methods on the instantiated AutoNumeric object, or the static functions directly by using the AutoNumeric class.

#### Set, get, format, unformat and other usual AutoNumeric functions

The following functions are available on all autoNumeric-managed elements:

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| set | Set the value (that will be formatted immediately) | anElement.set(42.76); |
| set | Set the value and update the setting in one go | anElement.set(42.76, { options }); |
| set | Set the value, but do not save the new state in the history table (used for undo/redo actions) | anElement.set(42.76, { options }, false); |
| setUnformatted | Set the value (that will not be formatted immediately) | anElement.setUnformatted(42.76); |
| setUnformatted | Set the value and update the setting in one go (the value will not be formatted immediately) | anElement.setUnformatted(42.76, { options }); |
| getNumericString | Return the unformatted number as a string | anElement.getNumericString(); |
| get | Alias for the .getNumericString() method (this is deprecated and will be removed soon™) | anElement.get(); |
| getFormatted | Return the formatted string | anElement.getFormatted(); |
| getNumber | Return the unformatted number as a number (Warning: If you are manipulating a number bigger than Number.MAX_SAFE_INTEGER, you will encounter problems if you try to retrieve it as a number and not a string) | anElement.getNumber(); |
| getLocalized | Return the localized unformatted number as a string | anElement.getLocalized(); |
| getLocalized | Return the localized unformatted number as a string, using the outputFormat option override passed as a parameter | anElement.getLocalized(forcedOutputFormat); |
| getLocalized | Idem above, but with a callback function and a forced outputFormat | anElement.getLocalized(forcedOutputFormat, callback); |
| getLocalized | Idem above, but with a callback function | anElement.getLocalized(callback); |
| get | Pass the result of the get function to the given callback, see here | anElement.get*(funcCallback); |
| reformat | Force the element to reformat its value again (in case the formatting has been lost) | anElement.reformat(); |
| unformat | Remove the formatting and keep only the raw unformatted value in the element (as a numeric string) | anElement.unformat(); |
| unformatLocalized | Remove the formatting and keep only the localized unformatted value in the element | anElement.unformatLocalized(); |
| unformatLocalized | Idem above, but using the outputFormat option override passed as a parameter | anElement.unformatLocalized(forcedOutputFormat); |
| isPristine | Return true if the current value is the same as when the element first got initialized (not set()) | anElement.isPristine(); |
| select | Select the formatted element content, based on the selectNumberOnly option | anElement.select(); |
| selectNumber | Select only the numbers in the formatted element content, leaving out the currency symbol, whatever the value of the selectNumberOnly option | anElement.selectNumber(); |
| selectInteger | Select only the integer part in the formatted element content, whatever the value of selectNumberOnly | anElement.selectInteger(); |
| selectDecimal | Select only the decimal part in the formatted element content, whatever the value of selectNumberOnly | anElement.selectDecimal(); |
| clear | Reset the element value to the empty string '' (or the currency sign, depending on the emptyInputBehavior option value) | anElement.clear(); |
| clear | Always reset the element value to the empty string '' as above, no matter the emptyInputBehavior option value | anElement.clear(true); |

Note: Most of them can be chained together, if needed.

##### Using callback functions with get* methods

All get* methods can accept a callback function as its argument (those methods being get, getNumericString, getFormatted, getNumber and getLocalized).
That callback is passed two parameters, the result of the get* method as its first argument, and the AutoNumeric object as its second.

This allows you to directly use the result of the get* functions without having to declare a temporary variable like so:
`js
function sendToServer(value) {
ajax(value);
}

console.log(The value ${anElement.getNumber(sendToServer)} has been sent to the server.);
`

In other words,
`js
// Using:
anElement.getNumericString(funcCallback);

// Is equivalent to doing:
const result = anElement.getNumericString();
funcCallback(result, anElement);
`

Note: The callback function behavior is slightly different when called on multiple elements via global.get methods.*

#### Un-initialize the AutoNumeric element

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| remove | Remove the autoNumeric listeners from the element (previous name : 'destroy'). Keep the element content intact. | anElement.remove(); |
| wipe | Remove the autoNumeric listeners from the element, and reset its value to '' | anElement.wipe(); |
| nuke | Remove the autoNumeric listeners from the element, then delete the DOM element altogether | anElement.nuke(); |


#### Node manipulation

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| node | Return the DOM element reference of the autoNumeric-managed element | anElement.node(); |
| parent | Return the DOM element reference of the parent node of the autoNumeric-managed element | anElement.parent(); |
| detach | Detach the current AutoNumeric element from the shared local 'init' list (which means any changes made on that local shared list will not be transmitted to that element anymore) | anElement.detach(); |
| detach | Idem above, but detach the given AutoNumeric element, not the current one | anElement.detach(otherAnElement); |
| attach | Attach the given AutoNumeric element to the shared local 'init' list. When doing that, by default the DOM content is left untouched. The user can force a reformat with the new shared list options by passing a second argument valued true. | anElement.attach(otherAnElement, reFormat = true); |


#### Format and unformat other numbers or DOM elements with an existing AutoNumeric element

You can use any AutoNumeric element to format or unformat other numbers or DOM elements.

This allows to format or unformat numbers, strings or directly other DOM elements without having to specify the options each time, since the current AutoNumeric object already has those settings set.

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| formatOther | This use the same function signature that when using the static AutoNumeric method directly (cf. below: AutoNumeric.format), but without having to pass the options | anElement.formatOther(12345, { options }); |
| formatOther | Idem above, but apply the formatting to the given DOM element by modifying its content directly | anElement.formatOther(domElement, { options }); |
| unformatOther | This use the same function signature that when using the static AutoNumeric method directly (cf. below: AutoNumeric.unformat), but without having to pass the options | anElement.unformatOther('1.234,56 €', { options }); |
| unformatOther | Idem above, but apply the unformatting to the given DOM element by modifying its content directly | anElement.unformatOther(domElement, { options }); |


#### Initialize other DOM Elements

Once you have an AutoNumeric element already setup correctly with the right options, you can use it as many times you want to initialize as many other DOM elements as needed (this works only on elements that can be managed by autoNumeric).

Whenever init is used to initialize other DOM elements, a shared local 'init' list of those elements is stored in the AutoNumeric objects.
This allows for neat things like modifying all those linked AutoNumeric elements globally, with only one call.

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| init | Use an existing AutoNumeric element to initialize another single DOM element with the same options | const anElement2 = anElement.init(domElement2); |
| init | If true is set as the second argument, then the newly generated AutoNumeric element will not share the same local element list as anElement | const anElement2 = anElement.init(domElement2, true); |
| init | Use an existing AutoNumeric element to initialize multiple other DOM elements from an Array, with the same options | const anElementsArray = anElement.init([domElement2, domElement3, domElement4]); |
| init | Use an existing AutoNumeric element to initialize multiple other DOM elements from a CSS selector, with the same options | const anElementsArray = anElement.init('.currency'); |


#### Perform actions globally on a shared 'init' list of AutoNumeric elements

This local 'init' list can be used to perform global operations on all those AutoNumeric elements, with one function call.

To do so, you must call the wanted function by prefixing .global before the method name (ie. anElement.global.set(42)).

Below are listed all the supported methods than can be called globally:

`js
anElement.global.set(2000); // Set the value 2000 in all the autoNumeric-managed elements that are shared on this element
anElement.global.setUnformatted(69);
[result1, result2, result3] = anElement.global.get(); // Return an array of results
[result1, result2, result3] = anElement.global.getNumericString(); // Return an array of results
[result1, result2, result3] = anElement.global.getFormatted(); // Return an array of results
[result1, result2, result3] = anElement.global.getNumber(); // Return an array of results
[result1, result2, result3] = anElement.global.getLocalized(); // Return an array of results
anElement.global.reformat();
anElement.global.unformat();
anElement.global.unformatLocalized();
anElement.global.unformatLocalized(forcedOutputFormat);
anElement.global.update({ options }); // Update the settings of each autoNumeric-managed elements
anElement.global.update({ options1 }, { options2 }, { options3 }); // Idem above, but accepts as many option objects as needed
anElement.global.isPristine(); // Return true is all the autoNumeric-managed elements are pristine, if their raw value hasn't changed
anElement.global.isPristine(false); // Idem as above, but also checks that the formatted value hasn't changed
anElement.global.clear(); // Clear the value in all the autoNumeric-managed elements that are shared on this element
anElement.global.remove();
anElement.global.wipe();
anElement.global.nuke();
`

The shared local list also provide list-specific methods to manipulate it:
`js
anElement.global.has(domElementOrAutoNumericObject); // Return true if the given AutoNumeric object (or DOM element) is in the local AutoNumeric element list
anElement.global.addObject(domElementOrAutoNumericObject); // Add an existing AutoNumeric object (or DOM element) to the local AutoNumeric element list, using the DOM element as the key
anElement.global.removeObject(domElementOrAutoNumericObject); // Remove the given AutoNumeric object (or DOM element) from the local AutoNumeric element list, using the DOM element as the key
anElement.global.removeObject(domElementOrAutoNumericObject, true); // Idem above, but keep the current AutoNumeric object in the local list if it's removed by itself
anElement.global.empty(); // Remove all elements from the shared list, effectively emptying it
anElement.global.empty(true); // Idem above, but instead of completely emptying the local list of each AutoNumeric objects, each one of those keeps itself in its own local list
[anElement0, anElement1, anElement2, anElement3] = anElement.global.elements(); // Return an array containing all the AutoNumeric elements that have been initialized by each other
anElement.global.getList(); // Return the Map object directly
anElement.global.size(); // Return the number of elements in the local AutoNumeric element list
`

##### Using callback functions with global.get* methods

Like for their get methods counterparts, global.get methods accepts a callback function.
However, the callback is executed only once and is passed an array of the get* function results as its first argument, while the AutoNumeric object being passed as its second one.

`js
// Using:
anElement.global.getNumericString(funcCallback);

// Is equivalent to doing:
const [result1, result2, result3] = anElement.global.getNumericString();
funcCallback([result1, result2, result3], anElement);
`

#### Form functions

autoNumeric elements provide special functions to manipulate the form they are a part of.
Those special functions really work on the parent element, instead of the element itself.

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| form | Return a reference to the parent element, null if it does not exist | anElement.form(); |
| form(forcedSearch) | Idem above, but will force a new search for the parent element, discarding any previously found one | anElement.form(true); |
| formNumericString | Return a string in standard URL-encoded notation with the form input values being unformatted | anElement.formNumericString(); |
| formFormatted | Return a string in standard URL-encoded notation with the form input values being formatted | anElement.formFormatted(); |
| formLocalized | Return a string in standard URL-encoded notation with the form input values, with localized values | anElement.formLocalized(); |
| formLocalized(forcedOutputFormat) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formLocalized(forcedOutputFormat); |
| formArrayNumericString | Return an array containing an object for each form element, with the values as numeric strings | anElement.formArrayNumericString(); |
| formArrayFormatted | Return an array containing an object for each form element, with the values as formatted strings | anElement.formArrayFormatted(); |
| formArrayLocalized | Return an array containing an object for each form element, with the values as localized numeric strings | anElement.formArrayLocalized(); |
| formArrayLocalized(forcedOutputFormat) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formArrayLocalized(forcedOutputFormat); |
| formJsonNumericString | Return a JSON string containing an object representing the form input values. This is based on the result of the formArrayNumericString() function. | anElement.formJsonNumericString(); |
| formJsonFormatted | Return a JSON string containing an object representing the form input values. This is based on the result of the formArrayFormatted() function. | anElement.formJsonFormatted(); |
| formJsonLocalized | Return a JSON string containing an object representing the form input values. This is based on the result of the formArrayLocalized() function. | anElement.formJsonLocalized(); |
| formJsonLocalized(forcedOutputFormat) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formJsonLocalized(forcedOutputFormat); |
| formUnformat | Unformat all the autoNumeric-managed elements that are a child to the parent element of this anElement input, to numeric strings | anElement.formUnformat(); |
| formUnformatLocalized | Unformat all the autoNumeric-managed elements that are a child to the parent element of this anElement input, to localized strings | anElement.formUnformatLocalized(); |
| formReformat | Reformat all the autoNumeric-managed elements that are a child to the parent element of this anElement input | anElement.formReformat(); |

The following functions can either take a callback, or not. If they don't, the default form.submit() function will be called.

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| formSubmitNumericString(callback) | Run the callback(value) with value being equal to the result of formNumericString() | anElement.formSubmitNumericString(callback); |
| formSubmitFormatted(callback) | Run the callback(value) with value being equal to the result of formFormatted() | anElement.formSubmitFormatted(callback); |
| formSubmitLocalized(callback) | Run the callback(value) with value being equal to the result of formLocalized() | anElement.formSubmitLocalized(callback); |
| formSubmitLocalized(forcedOutputFormat, callback) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formSubmitLocalized(forcedOutputFormat, callback); |

For the following methods, the callback is mandatory:

| Method | Description | Call example |
| :----------------: | :-----------: | :-----------: |
| formSubmitArrayNumericString(callback) | Run the callback(value) with value being equal to the result of formArrayNumericString() | anElement.formSubmitArrayNumericString(callback); |
| formSubmitArrayFormatted(callback) | Run the callback(value) with value being equal to the result of formArrayFormatted() | anElement.formSubmitArrayFormatted(callback); |
| formSubmitArrayLocalized(callback, forcedOutputFormat) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formSubmitArrayLocalized(callback, forcedOutputFormat); |
| formSubmitJsonNumericString(callback) | Run the callback(value) with value being equal to the result of formJsonNumericString() | anElement.formSubmitJsonNumericString(callback); |
| formSubmitJsonFormatted(callback) | Run the callback(value) with value being equal to the result of formJsonFormatted() | anElement.formSubmitJsonFormatted(callback); |
| formSubmitJsonLocalized(callback, forcedOutputFormat) | Idem above, but with the possibility of overriding the outputFormat option | anElement.formSubmitJsonLocalized(callback, forcedOutputFormat); |


#### Function chaining

Most of those instantiated functions can be chained which allow to be less verbose and more concise.

`js
// On one element
anElement.french()
.set(42)
.update({ options })
.formSubmitJsonNumericString(callback)
.clear();

// On multiple elements
anElement.global.set(72)
.global.clear()
.set(25)
.global.getNumericString();
`

$3

Without having to initialize any AutoNumeric object, you can directly use the static AutoNumeric class functions.

Note: Some of those functions can be used in Web Workers.

| Method | Description | Call example |
| :---------------- | :-----------: | :-----------: |
| areSettingsValid | Return true in the settings are valid | AutoNumeric.areSettingsValid({ options }) |
| format | Format the given number with the given options. This returns the formatted value as a string. | AutoNumeric.format(12345.21, { options }); |
| format | Idem above, but using a numeric string as the first parameter | AutoNumeric.format('12345.21', { options }); |
| format | Idem above, but you can pass as many option objects you want to this function, the latter overwriting the previous ones. This allows to correctly format currencies that have a predefined option as its base, but has been slightly modified. | AutoNumeric.format('12345.21', { options1 }, { options2 }); |
| format | Idem above, using multiple option objects in one array. This way allows for using a pre-defined option name. | AutoNumeric.format('12345.21', [{ options1 }, 'euroPos', { options2 }]); |
| format | Format the domElement value (or textContent) with the given options and returns the formatted value as a string. This does not update that element value. | AutoNumeric.format(domElement, { options }); |
| formatAndSet | Format the domElement value with the given options and returns the formatted value as a string. This function does update that element value with the newly formatted value in the process. | AutoNumeric.formatAndSet(domElement, { options }); |
| getAutoNumericElement | Return the AutoNumeric object that manages the given DOM element | AutoNumeric.getAutoNumericElement(domElement)
AutoNumeric.getAutoNumericElement('#theInput') |
| getDefaultConfig | Return the default autoNumeric settings | AutoNumeric.getDefaultConfig() |
| getFormatted | Return the formatted string from the given DOM element or query selector.
This can accept a callback that is passed the result of getFormatted and a reference to the AutoNumeric object. | AutoNumeric.getFormatted(domElement, callback);
AutoNumeric.getFormatted('#theInput') |
| getLocalized | Return the localized unformatted number as a string from the given DOM element or query selector.
This can accept a callback that is passed the result of getLocalized and a reference to the AutoNumeric object. | AutoNumeric.getLocalized(domElement, forcedOutputFormat, callback);
AutoNumeric.getLocalized('#theInput') |
| getNumber | Return the unformatted number as a number from the given DOM element or query selector (The same warnings got the non-static getNumber method applies here too).
This can accept a callback that is passed the result of getNumber and a reference to the AutoNumeric object. | AutoNumeric.getNumber(domElement, callback);
AutoNumeric.getNumber('#theInput') |
| getNumericString | Return the unformatted number as a string from the given DOM element or query selector.
This can accept a callback that is passed the result of getNumericString and a reference to the AutoNumeric object. | AutoNumeric.getNumericString(domElement, callback)
AutoNumeric.getNumericString('#theInput') |
| getPredefinedOptions | Return all the predefined options in one object | AutoNumeric.getPredefinedOptions() |
| getPredefinedOptions | Return a specific pre-defined language option object | AutoNumeric.getPredefinedOptions().French |
| isManagedByAutoNumeric | Return true if the given DOM element (or selector string) has an AutoNumeric object that manages it. | AutoNumeric.isManagedByAutoNumeric(domElement);
AutoNumeric.isManagedByAutoNumeric('#theInput'); |
| localize | Unformat and localize the given formatted string with the given options. This returns a string. | AutoNumeric.localize('1.234,56 €', { options }); |
| localize | Idem as above, but return the localized DOM element value. This does not update that element value. | AutoNumeric.localize(domElement, { options }); |
| localizeAndSet | Unformat and localize the domElement value with the given options and returns the localized value as a string. This function does update that element value with the newly localized value in the process. | AutoNumeric.localizeAndSet(domElement, { options }); |
| mergeOptions | Accepts an array of option objects and / or pre-defined option names, and return a single option object where the latter element overwrite the settings from the previous ones | AutoNumeric.mergeOptions(['euro', { currencySymbol: '#' }]); |
| reformatAndSet | Recursively format all the autoNumeric-managed elements that are a child to the referenceToTheDomElement element given as a parameter (this is usually the parent element), with the settings of each AutoNumeric elements. | AutoNumeric.reformatAndSet(referenceToTheDomElement); |
| set` | Set the given value on the AutoNumeric object
