Simple copy paste function in JavaScript

Question

How I can make simple copy and paste for text in JavaScript? I would like to achieve that when I select some text in a textarea, then I can click on a button to copy it, then I can go to another page right click in another textarea and choose paste.

Answer 1

Take a look at this library: https://github.com/zeroclipboard/zeroclipboard

You cannot access the clipboard in JavaScript, meaning flash is more or less your only option.

Answer 2

Try this:

function copy() {
 if(window.clipboardData) {
   window.clipboardData.clearData();
   window.clipboardData.setData("Text", document.getElementById('txToCopy').value);
 } 
}

function paste() {
 if(window.clipboardData) {   
   document.getElementById('txToPaste').value = window.clipboardData.getData("Text");
 } 
}

<a href="javascript:copy();">Copy</a>
<br />
<input type="text" name="txToCopy" id ="txToCopy"/>
<br /><br />
<a href="javascript:paste();">Paste</a>
<br />
<input type="text" name="txToPaste" id="txToPaste"/>

It's a simple copy and paste function. Its working well in IE.

I hope it helps you.
