# clipboard.js [![Build Status](http://img.shields.io/travis/zenorocha/clipboard.js/master.svg?style=flat)](https://travis-ci.org/zenorocha/clipboard.js) ![Killing Flash](https://img.shields.io/badge/killing-flash-brightgreen.svg?style=flat) > Modern copy to clipboard. No Flash. Just 2kb

## Why Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework. That's why clipboard.js exists. ## Install You can get it on npm. ``` npm install clipboard --save ``` Or bower, too. ``` bower install clipboard --save ``` If you're not into package management, just [download a ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip) file. ## Setup First, include the script located on the `dist` folder. ```html ``` Or load it from a CDN. ```html ``` Now, you need to instantiate it using a DOM selector. This selector corresponds to the trigger element(s), for example ` ``` ### 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.

```html ``` As you may expect, the `cut` action only works on `` or `

` 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.

```html

<button class="btn" 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.

```js
var clipboard = new Clipboard('.btn');

clipboard.on('success', function(e) {
    console.info('Action:', e.action);
    console.info('Text:', e.text);
    console.info('Trigger:', e.trigger);

e.clearSelection();
});

clipboard.on('error', function(e) {
    console.error('Action:', e.action);
    console.error('Trigger:', e.trigger);
});
```

## Advanced Options

If you don't want to modify your HTML, there's a pretty handy imperative API for you to use. All you need to do is declare a function, do your thing, and return a value.

For instance, if you want to dynamically set a `target`, you'll need to return a Node.

```js
new Clipboard('.btn', {
    target: function(trigger) {
        return trigger.nextElementSibling;
    }
});
```

If you want to dynamically set a `text`, you'll return a String.

```js
new Clipboard('.btn', {
    text: function(trigger) {
        return trigger.getAttribute('aria-label');
    }
});
```

Also, with are working with single page apps, you may want to manage the lifecycle of the DOM more precisely. Here's how you clean up the events and objects that we create.

```js
var clipboard = new Clipboard('.btn');
clipboard.destroy();
```

## Browser Support

This library relies on both [Selection](https://developer.mozilla.org/en-US/docs/Web/API/Selection) and [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) APIs. The second one is supported in the following browsers.

| <img src="http://clipboardjs.com/assets/images/chrome.png" width="48px" height="48px" alt="Chrome logo"> | <img src="http://clipboardjs.com/assets/images/firefox.png" width="48px" height="48px" alt="Firefox logo"> | <img src="http://clipboardjs.com/assets/images/ie.png" width="48px" height="48px" alt="Internet Explorer logo"> | <img src="http://clipboardjs.com/assets/images/opera.png" width="48px" height="48px" alt="Opera logo"> | <img src="http://clipboardjs.com/assets/images/safari.png" width="48px" height="48px" alt="Safari logo"> |
|:---:|:---:|:---:|:---:|:---:|
| 42+ ✔ | 41+ ✔ | 9+ ✔ | 29+ ✔ | Nope ✘ |

Although copy/cut operations with [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) aren't supported on Safari yet (including mobile), it gracefully degrades because [Selection](https://developer.mozilla.org/en-US/docs/Web/API/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](http://clipboardjs.com) on Safari.
