A simple ember wrapper around clipboard.js (no flash)

Demo Page

http://jkusa.github.io/ember-cli-clipboard

Usage

$3

``hbs

@text='text to be copied'
@onSuccess={{this.onSuccess}}
@onError={{this.onError}}
>
Click To Copy



@text={{this.getText}}
@onSuccess={{this.onSuccess}}
@onError={{this.onError}}
>
Click To Copy



id='url'
type='text'
value='https://github.com/jkusa/ember-cli-clipboard'
/>
@target='#url'
@onSuccess={{this.onSuccess}}
@onError={{this.onError}}
>
Click To Copy

`

#### Arguments

- text - string value or action that returns a string to be copied
- target - selector string of element or action that returns an element from which to copy text
- action - string value of operation: copy or cut (default is copy)
- container - selector string or element object of containing element. "For use in Bootstrap Modals or with any other library that changes the focus you'll want to set the focused element as the container value".
- delegateClickEvent - clipboard.js defaults event listeners to the body in order to reduce memory footprint if there are hundreds of event listeners on a page. If you want to scope the event listener to the copy button, set this property to false
- buttonType - string value of the button's type attribute (for Ember < 3.25.x, see below)

Any HTML button attribute passed to the component will be "splatted" on the button element. The one exception to this is the type attribute due to this issue < Ember 3.25.x.

#### Actions

The following clipboard.js custom events are sent as actions

- onSuccess sent on successful copy
- onError sent on failed copy

More information about the clipboard.js events can be found here

$3

Under the hood the component is powered by a {{clipboard}} element modifier. This can be used directly as an alternative to the component. It has the same argument contract as the component except for the exclusion of the buttonType argument.

`hbs
class='button is-outline'
type='button'
{{clipboard text='text to be copied' onSuccess=this.onSuccess}}
>
Click To Copy

`

$3

The helper is-clipboard-supported can be used to check if clipboard.js is supported or not.

`hbs
{{#if (is-clipboard-supported)}}

Click To Copy

{{/if}}
`

Test Helpers

Some browsers do not allow simulated clicks to fire execCommand('copy'). This makes testing difficult. To assist with integration testing, the following test helpers are available to test the wiring of the success and error action handlers.

$3

- triggerCopySuccess(selector='.copy-btn')
- triggerCopyError(selector='.copy-btn')

`js
// tests/acceptance/my-test.js

import {
triggerCopyError,
triggerCopySuccess,
} from 'ember-cli-clipboard/test-support';
`

Example:

`js
// tests/acceptance/my-test.js

test('copy button message', async function (assert) {
assert.expect(3);

await visit('/');
assert.dom('.alert').doesNotExist('no alert message is initially present');

triggerCopySuccess();

assert
.dom('.alert.alert-success')
.exists('a success message is displayed when a copy is successful');

triggerCopyError();

assert
.dom('.alert.alert-info')
.exists('an error message is displayed when a copy is unsuccessful');
});
`

$3

- triggerCopySuccess(selector='.copy-btn')
- triggerCopyError(selector='.copy-btn')

Example:

`js
// tests/integration/components/my-test.js

// if using NEW ember testing api
import {
triggerCopyError,
triggerCopySuccess,
} from 'ember-cli-clipboard/test-support';

test('copy-button integration', async function (assert) {
assert.expect(2);

this.set('onSuccess', () => {
assert.ok(true, 'success action handler correctly fired');
});

this.set('onError', () => {
assert.ok(true, 'error action handler correctly fired');
});

await render(hbs
class="my-copy-btn"
@text="text to be copied"
@onSuccess={{this.onSuccess}}
@onError={{this.onError}}
>
Click To Copy

);

//If using NEW ember testing api
triggerCopyError('.my-copy-btn');
triggerCopySuccess('.my-copy-btn');
});
