Angularjs directive for clipboard.js by @zenorocha

Install

You can get it on npm.

npm install ngclipboard --save

Or bower, too.

bower install ngclipboard --save

If you're not into package management, just download a ZIP file.

Setup

First, include angularjs and clipboard.js into your document.

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src="https://cdn.rawgit.com/zenorocha/clipboard.js/master/dist/clipboard.min.js"></script>

Then Include ngclipboard.js.

<script src="dist/ngclipboard.min.js"></script>

Add ngclipboard dependency to your module

var myApp = angular.module('app', ['ngclipboard']);

Finally, add ngclipboard directive to the wanted html element.

<button class="btn" ngclipboard data-clipboard-text="Just because you can doesn't mean you should — clipboard.js">
    Copy to clipboard
</button>

Usage

We're living a declarative renaissance, that's why we decided to take advantage of HTML5 data attributes for better usability.

Copy text from another element

A pretty common use case is to copy content from another element. You can do that by adding a data-clipboard-target attribute in your trigger element.

The value you include on this attribute needs to match another's element selector.

<!-- Target -->
<input id="foo" value="https://github.com/sachinchoolur/ngclipboard.git">

<!-- Trigger -->
<button class="btn" ngclipboard data-clipboard-target="#foo">
    <img src="assets/clippy.svg" alt="Copy to clipboard">
</button>

Cut text from another element

Additionally, you can define a data-clipboard-action attribute to specify if you want to either copy or cut content.

If you omit this attribute, copy will be used by default.

<!-- Target -->
<textarea id="bar">Mussum ipsum cacilds...</textarea>

<!-- Trigger -->
<button class="btn" ngclipboard data-clipboard-action="cut" data-clipboard-target="#bar">
    Cut to clipboard
</button>

As you may expect, the cut action only works on <input> or <textarea> elements.

Copy text from attribute

Truth is, you don't even need another element to copy its content from. You can just include a data-clipboard-text attribute in your trigger element.

<!-- Trigger -->
<button class="btn" ngclipboard data-clipboard-text="Just because you can doesn't mean you should — clipboard.js">
    Copy to clipboard
</button>

Events

There are cases where you'd like to show some user feedback or capture what has been selected after a copy/cut operation.

That's why we fire custom events such as success and error for you to listen and implement your custom logic.

ngclipboard provides you two attributes called ngclipboard-success and ngclipboard-error to listen the clipboard events and implement your custom logic.

<button class="btn" ngclipboard ngclipboard-success="onSuccess(e);" ngclipboard-error="onError(e);" data-clipboard-text="Just because you can doesn't mean you should — clipboard.js">
    Copy to clipboard
</button>

// You can still access the clipboard.js event
$scope.onSuccess = function(e) {
    console.info('Action:', e.action);
    console.info('Text:', e.text);
    console.info('Trigger:', e.trigger);

    e.clearSelection();
};

$scope.onError = function(e) {
    console.error('Action:', e.action);
    console.error('Trigger:', e.trigger);
}

Browser Support

This library relies on both Selection and execCommand APIs. The second one is supported in the following browsers.

42+ ✔	41+ ✔	9+ ✔	29+ ✔	Nope ✘

Although copy/cut operations with execCommand aren't supported on Safari yet (including mobile), it gracefully degrades because Selection is supported.

That means you can show a tooltip saying Copied! when success event is called and Press Ctrl+C to copy when error event is called because the text is already selected.

For a live demonstration, open this site on Safari.
