[![GitHub Latest Release](https://badge.fury.io/gh/zeroclipboard%2Fzeroclipboard.png)](https://github.com/zeroclipboard/zeroclipboard) [![Build Status](https://secure.travis-ci.org/zeroclipboard/zeroclipboard.png?branch=master)](https://travis-ci.org/zeroclipboard/zeroclipboard) [![Coverage Status](https://coveralls.io/repos/zeroclipboard/zeroclipboard/badge.png?branch=master)](https://coveralls.io/r/zeroclipboard/zeroclipboard?branch=master) [![Dependency Status](https://david-dm.org/zeroclipboard/zeroclipboard.png?theme=shields.io)](https://david-dm.org/zeroclipboard/zeroclipboard) [![Dev Dependency Status](https://david-dm.org/zeroclipboard/zeroclipboard/dev-status.png?theme=shields.io)](https://david-dm.org/zeroclipboard/zeroclipboard#info=devDependencies)
The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible [Adobe Flash](http://en.wikipedia.org/wiki/Adobe_Flash) movie and a [JavaScript](http://en.wikipedia.org/wiki/JavaScript) interface. The "Zero" signifies that the library is invisible and the user interface is left entirely up to you.
This is achieved by automatically floating the invisible movie on top of a [DOM](http://en.wikipedia.org/wiki/Document_Object_Model) element of your choice. Standard mouse events are even propagated out to your DOM element, so you can still have rollover and mousedown effects.
## Limitations
### User Interaction Required
Due to browser and Flash security restrictions, this clipboard injection can _**ONLY**_ occur when
the user clicks on the invisible Flash movie. A simulated `click` event from JavaScript will not
suffice as this would enable [clipboard poisoning](http://www.computerworld.com/s/article/9117268/Adobe_patches_Flash_clickjacking_and_clipboard_poisoning_bugs).
### Other Limitations
For a complete list of limitations, see [docs/instructions.md#limitations](docs/instructions.md#limitations).
## Simple Example
```html
<html>
<body>
<button id="copy-button" data-clipboard-text="Copy Me!" title="Click to copy me.">Copy to Clipboard</button>
<script src="ZeroClipboard.js"></script>
<script src="main.js"></script>
</body>
</html>
```
```js
// main.js
var client = new ZeroClipboard( document.getElementById("copy-button") );
client.on( "ready", function( readyEvent ) {
// alert( "ZeroClipboard SWF is ready!" );
client.on( "aftercopy", function( event ) {
// `this` === `client`
// `event.target` === the element that was clicked
event.target.style.display = "none";
alert("Copied text to clipboard: " + event.data["text/plain"] );
} );
} );
```
See [docs/instructions.md](docs/instructions.md) for more advanced options in using the library on your site.
See [docs/api/ZeroClipboard.md](docs/api/ZeroClipboard.md) for the complete API documentation.
Here is a working [test page](http://zeroclipboard.org/#demo) where you can try out ZeroClipboard in your browser.
## Testing ZeroClipboard Locally
To test the page [demo page](http://zeroclipboard.org/#demo) locally, clone the [website repo](https://github.com/zeroclipboard/zeroclipboard.org).
## Support
This library is fully compatible with Flash Player 11.0.0 and above, which requires
that the clipboard copy operation be initiated by a user click event inside the
Flash movie. This is achieved by automatically floating the invisible movie on top
of a [DOM](http://en.wikipedia.org/wiki/Document_Object_Model) element of your
choice. Standard mouse events are even propagated out to your DOM element, so you
can still have rollover and mousedown effects with just a _little_ extra effort.
ZeroClipboard `v2.x` is expected to work in IE9+ and all of the evergreen browsers.
Although support for IE7 & IE8 was officially dropped in `v2.0.0`, it was actually
still _technically_ supported through `v2.0.2`.
