Angular date picker
npm install angular4-datepickerts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MyTestApp } from './my-test-app';
import { MyDatePickerModule } from 'mydatepicker';
@NgModule({
imports: [ BrowserModule, MyDatePickerModule ],
declarations: [ MyTestApp ],
bootstrap: [ MyTestApp ]
})
export class MyTestAppModule {}
`
3. If you are using __systemjs__ package loader add the following mydatepicker properties to the __System.config__:
`js
(function (global) {
System.config({
paths: {
'npm:': 'node_modules/'
},
map: {
// Other components are here...
'mydatepicker': 'npm:mydatepicker/bundles/mydatepicker.umd.min.js'
},
packages: {
}
});
})(this);
`
Usage
Use one of the following three options.
$3
In this option the ngModel binding is used. Here
is an example application. It shows how to use the __ngModel__.
To use ngModel define the application class as follows:
`ts
import {IMyDpOptions} from 'mydatepicker';
// other imports here...
export class MyTestApp {
public myDatePickerOptions: IMyDpOptions = {
// other options...
dateFormat: 'dd.mm.yyyy',
};
// Initialized to specific date (09.10.2018).
public model: any = { date: { year: 2018, month: 10, day: 9 } };
constructor() { }
}
`
Add the following snippet inside your template:
`html
`
$3
In this option the value accessor of reactive forms is used. Here
is an example application. It shows how to use the __formControlName__.
To use reactive forms define the application class as follows:
`ts
import {IMyDpOptions} from 'mydatepicker';
// other imports here...
export class MyTestApp implements OnInit {
public myDatePickerOptions: IMyDpOptions = {
// other options...
dateFormat: 'dd.mm.yyyy',
};
public myForm: FormGroup;
constructor(private formBuilder: FormBuilder) { }
ngOnInit() {
this.myForm = this.formBuilder.group({
// Empty string or null means no initial value. Can be also specific date for
// example: {date: {year: 2018, month: 10, day: 9}} which sets this date to initial
// value.
myDate: [null, Validators.required]
// other controls are here...
});
}
setDate(): void {
// Set today date using the patchValue function
let date = new Date();
this.myForm.patchValue({myDate: {
date: {
year: date.getFullYear(),
month: date.getMonth() + 1,
day: date.getDate()}
}});
}
clearDate(): void {
// Clear the date using the patchValue function
this.myForm.patchValue({myDate: null});
}
}
`
Add the following snippet inside your template:
`html
`
$3
In this option the mydatepicker sends data back to host application using callbacks. Here
is an example application. It shows how to use callbacks.
To use callbacks define the application class as follows:
`js
import {IMyDpOptions, IMyDateModel} from 'mydatepicker';
// other imports here...
export class MyTestApp {
myDatePickerOptions: IMyDpOptions = {
// other options...
dateFormat: 'dd.mm.yyyy',
};
constructor() { }
// dateChanged callback function called when the user select the date. This is mandatory callback
// in this option. There are also optional inputFieldChanged and calendarViewChanged callbacks.
onDateChanged(event: IMyDateModel) {
// event properties are: event.date, event.jsdate, event.formatted and event.epoc
}
}
`
Add the following snippet inside your template:
`html
(dateChanged)="onDateChanged($event)">
`

An ISO 639-1 language code can be provided as shorthand for the following options (dayLabels, monthLabels, dateFormat, todayBtnTxt, firstDayOfWeek and sunHighlight).
Currently supported languages: __en__, __fr__, __ja__, __fi__, __es__, __hu__, __sv__, __nl__, __ru__, __uk__, __no__, __tr__,
__pt-br__, __de__, __it__, __it-ch__, __pl__, __my__, __sk__, __sl__, __zh-cn__, __he__, __ro__, __ca__, __id__, __en-au__, __am-et__, __cs__, __el__, __kk__,
__th__, __ko-kr__, __da__, __lt__, __vi__, __bn__, __bg__, __hr__, __ar__ and __is__.
The __locale__ options can be override by __options__ attribute.
* new locale data can be added to this
file. If you want to add a new locale create a pull request.
* locales can be tested here
$3
Provide the initially chosen date that will display both in the text input field
and provide the default for the popped-up selector.
Type of the __selDate__ attribute can be a string or an IMyDate object.
* the string must be in the same format as the __dateFormat__ option is. For example '2016-06-26'
* the object must be in the IMyDate format. For example: {year: 2016, month: 6, day: 26}
Here is an example on how to use this attribute.
$3
If __selDate__ is not specified, when the calendar is opened, it will
ordinarily default to selecting the current date. If you would prefer
a different year and month to be the default for a freshly chosen date
picking operation, specify a __defaultMonth__ attribute.
Value of the defaultMonth attribute can be:
* IMyDefaultMonth object. The value of __defMonth__ property can be a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: __08-2016__ or __08/2016__.
* a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: __08-2016__ or __08/2016__.
Here is an example on how to use this attribute.
$3
Placeholder text in the input field. Here is an example on how to use this attribute.
$3
Boolean value indicating is the component disabled or not. Here is an example on how to use this attribute.
$3
Selector can be opened or closed using this attribute. Value of the selector attribute can be:
* IMySelector object. The value of __open__ property is a boolean value indicating the state of the selector.
Here is an example on how to use this attribute. Another way is to call a function of mydatepicker. Here is an example.
