Copy the text selection to Clipboard, using Javascript

by Marco Pracucci Comments

Few days ago, Firefox announced the support to document.execCommand("copy") in the upcoming version 41.0 (currently in Beta). This change makes a step forward towards a Flash-free world (fallbacks are Flash based). Copying text selection to Clipboard is now available on all modern browsers, except Safari.

How it works

The execCommand("copy") API is only available during a user-triggered callback (ie. a click). When triggered, it copies the current selection to the clipboard. Using is is very straightforward and just requires a couple of lines of code.

<textarea id="input">Some text to copy.</textarea>
<button id="copy-button">Copy</button>

    var input  = document.getElementById("input");
    var button = document.getElementById("copy-button");

    button.addEventListener("click", function (event) {

Browsers support

To keep it simple, most modern browers are supported, except Safari. It’s actually an huge lack, we hope will get fixed soon.

Chrome > 43.0.2356
Firefox >= 41.0
Opera >= 30 (release notes)
IE >= 9 (allows it to be called at any time, but prompts a confirmation dialog)
Safari Not supported
