A tested datepicker component for Ember CLI projects including test helpers for your own acceptance tests.
npm install ember-pikaday
ember-pikaday provides a datepicker modifier & components for Ember using the Pikaday library.
This addon is fully integration tested, and it provides test helpers to interact with the datepicker in your own tests.
Prerequisites:
- Ember.js v3.28 or above
- Embroider or ember-auto-import v2
Optional prerequisites:
- If you use the backward-compatible moment or moment-timezone and you should remember to configure your locale and timezone requirements. See Using Moment.js in Ember Apps & Addons.
- But if you only use the new modifier, moment or moment-timezone are optional. Pikaday itself uses them if they present, but doesn't require them.
Anti-prerequisites:
- Remove ember-cli-moment-shim from your app. Earlier versions of this addon required it, but now it will only give you a redundant copy with the one provided by ember-auto-import.
In order to give apps control over styling, the default CSS does not load unless you tell it to. The recommended way to load the CSS is to create this file:
``js
// app/modifiers/pikaday.js
/ Opt-in to using pikaday's default CSS /
import 'ember-pikaday/pikaday.css';
export { default } from 'ember-pikaday/modifiers/pikaday';
`
This guarantees that the CSS will load whenever your app uses the {{pikaday}} modifier (and the {{pikaday}} modifier is used internally by all the other provided components, so this covers them too).
The {{pikaday}} modifier invokes new Pikaday() with your element as Pikaday's field option:
`hbs`
format='DD.MM.YYYY'
value=this.startDate
onSelect=this.setStartDate
}}
/>
The optional value argument can be used to synchronize external changes into Pikaday. Internally, we do this using Pikaday's setDate.
All other named arguments are passed directly to Pikaday, so see Pikaday's configuration docs.
The only behaviors this modifier adds to the stock Pikaday are:
- if you set your element's disabled attribute we will close Pikaday if it had been open.
While the input shows a formatted date to the user, the value attribute can be any valid JavaScript date including Date object. If the application sets the attribute without a user interaction the datepicker updates accordingly.
`handlebars`
You can also pass in other closure actions to handle onOpen, onClose and onDraw events.
`handlebars`
You can also change the default format from DD.MM.YYYY to any format string supported by Moment.js.
`handlebars`
You can define a theme which will be a CSS class that can be used as a hook for styling different themes.
`handlebars`
You can change the yearRange. It defaults to 10. the yearRange can be a
single number or two comma separated years.
`handlebars`
`handlebars`
If the second year of the comma separated years is set to currentYear, it sets
the maximum selectable year to the current year.
`handlebars`
The readonly attribute is supported as binding so you can make the input readonly for mobile or other use cases.
`handlebars`
The placeholder attribute is supported as binding so you can improve the user experience of your interface.
`handlebars`
The disabled attribute is supported as binding so you can disabled the datepicker entirely.
If the datepicker is shown to the user and it gets disabled it will close the datepicker itself.
`handlebars`
The firstDay attribute is supported as a binding so you can set the first day of the calendar week.
Defaults to Monday.
- 0 = Sunday
- 1 = Monday
- etc...
`handlebars`
The minDate attribute is supported as a binding so you can set the earliest date that can be selected.
`handlebars`
The maxDate attribute is supported as a binding so you can set the latest date that can be selected.
`handlebars`
#### Return dates in UTC time zone
The date returned by ember-pikaday is in your local time zone due to the JavaScript default behavior of new Date(). This can lead to problems when your application converts the date to UTC. In additive time zones (e.g. +0010) the resulting converted date could be yesterdays date. You can force the component to return a date with the UTC time zone by passing useUTC=true to it.
`handlebars`
ember-pikaday will not automatically convert the date to UTC if your application is setting the datepicker value directly!
#### Using pikaday specific options
You can pass any custom pikaday option through the component like this
`handlebars`
Please refer to pikaday configuration
If you don't want to show an input field, you can use the component instead of . It has the same API, but doesn't support onOpen and onClose. When disabled=true on a pikaday-inputless, the datepicker gets hidden.
Localizing the datepicker is possible in two steps. To localize the output of the datepicker, this is the formatted string visible in the input field, you simply include all the locales by following the ember-cli-moment-shim instructions and include the following in your ember-cli-build.js
`js`
app.import('node_modules/moment/locale/de.js');
To localize the datepicker itself, this is the popup you see after clicking the input, a little more work is necessary. The preferred way to do this is to implement a custom component that extends the PikadayInput component and customizes the i18n attribute. The following example uses the translations provided by Moment.js - naturally you can use your own localized strings instead.
`js
// app/components/pikaday-input.js
import PikadayInput from "ember-pikaday/components/pikaday-input";
import moment from "moment";
export default PikadayInput.extend({
init(...args) {
this._super(args);
this.i18n = {
previousMonth: 'Vorheriger Monat',
nextMonth: 'Nächster Monat',
months: moment.localeData()._months,
weekdays: moment.localeData()._weekdays,
weekdaysShort: moment.localeData()._weekdaysShort,
};
},
});
`
`handlebars`
{{#if showPika}}
{{/if}}
`js`
// app/controller/index.js
import Ember from 'ember';
export default Ember.Controller.extend({
actions: {
togglePika() {
this.toggleProperty('showPika');
},
},
});
`handlebars
{{action 'hidePika' on='mouseLeave'}}
>
Hover me to pika
{{#if showPika}}
{{/if}}
js
// app/controller/index.jsimport Controller from '@ember/controller';
export default Controller.extend({
actions: {
showPika() {
this.set('showPika', true);
},
hidePika() {
this.set('showPika', false);
},
},
});
`Test Helpers
The test helpers provided by
allow you to interact with the datepicker in your integration and acceptance tests.$3
To open the datepicker use
click from the @ember/test-helpers package:`js
import { click } from '@ember/test-helpers';await click('.my-pikaday-input');
`$3
Pikaday can be closed with the provided
helper:`js
import { close as closePikaday } from 'ember-pikaday/test-support';await closePikaday('.my-pikaday-input');
`$3
An
, like a page object, provides helpers for getting and setting dates in a date picker:`js
import { click } from '@ember/test-helpers';
import { Interactor as Pikaday } from 'ember-pikaday/test-support';await click('#my-datepicker');
await Pikaday.selectDate(new Date(1989, 3, 28));
`There are also methods available to check if a specific day, month or year is selected:
js
await Interactor.selectDate(new Date(1989, 3, 28));assert.equal(Interactor.selectedYear(), 1989);
assert.equal(Interactor.selectedMonth(), 3);
assert.equal(Interactor.selectedDay(), 28);
`Usage in Template Tag Format
For usage in
or gjs files, modifier and components are exported from the index:`gts
import { pikaday, PikadayInput, PikadayInputless } from 'ember-pikaday';function doSomethingWithSelectedValue(selectedDate) {
alert(selectedDate);
}
{{pikaday
format='DD.MM.YYYY'
value=this.startDate
onSelect=this.setStartDate
}}
/>
