ember-cli-clipboard

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

Demo Page

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

Usage

<!-- Set text directly -->
{{#copy-button
  clipboardText="text to be copied"
  success=(action "success")
  error=(action "error")
}}
  Click To Copy
{{/copy-button}}

<!-- Get text from target element -->
<input id="url" type="text" value="https://github.com/jkusa/ember-cli-clipboard">
{{#copy-button
  clipboardTarget="#url"
  success=(action "success")
  error=(action "error")
}}
  Click To Copy
{{/copy-button}}

Properties

• clipboardText - string value to be copied
• clipboardTarget - selector string of element from which to copy text
• clipboardAction - string value of operation: copy or cut (default is copy)
• 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
• title - string value of the button's title attribute
• buttonType - string value of the button's type attribute
• disabled - boolean value of the button's disabled attribute
• aria-label - string value of the button's aria-label attribute

Actions

The following clipboard.js custom events are sent as actions

• success sent on successful copy
• error sent on failed copy

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

Template Helper

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

{{#if (is-clipboard-supported)}}
  {{#copy-button clipboardTarget="#url"}}
    Click To Copy
  {{/copy-button}}
{{/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.

Acceptance Test Helpers

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

If you are using the NEW Ember Testing API, available in ember-cli-qunit >= 4.2 and ember-cli-mocha >= 0.15.0, then you can simply import the test helpers where needed (for both acceptance and integration tests).

// tests/acceptance/my-test.js

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

Otherwise, to use the helpers in acceptance tests you need to register them in the /tests/helpers/start-app.js file.

// tests/helpers/start-app.js

import registerClipboardHelpers from '../helpers/ember-cli-clipboard';

registerClipboardHelpers();

export default function startApp(attrs) {

...

Example:

// tests/acceptance/my-test.js


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

  visit('/');
  andThen(() => {
    assert.notOk(!!find('.alert').length,
      'no alert message is initially present');
  });

  triggerCopySuccess();

  andThen(() => {
    assert.ok(!!find('.alert.alert-success').length,
      'a success message is displayed when a copy is successful');
  });

  triggerCopyError();

  andThen(() => {
    assert.ok(!!find('.alert.alert-info').length,
      'an error message is displayed when a copy is unsuccessful');
  });
});

Integration Test Helpers

• New Testing API (ember-cli-qunit >= 4.2 or ember-cli-mocha >= 0.15.0)

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

• Old Testing API

  • triggerSuccess(context, selector='.copy-btn')
  • triggerError(context, selector='.copy-btn')

Example:

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

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

// if using OLD ember testing api
import {
  triggerError,
  triggerSuccess
} from '../../helpers/ember-cli-clipboard';

...

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

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

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

  this.render(hbs`
    {{#copy-button
      classNames="my-copy-btn"
      clipboardText="text to copy"
      success=(action success)
      error=(action error)
    }}
      Click To Copy
    {{/copy-button}}
  `);

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

  //If using OLD ember testing api
  triggerError(this, '.my-copy-btn');
  triggerSuccess(this, '.my-copy-btn');
});
