but it will not work as needed . I attach my working code along with this .. pls open index.html in browser
and try it . Do any one can pls give a javascript solution to copy textarea content to clipboard...

Thanks,
Anes

There isn't one so you can't.

Or rather you can, but ONLY in Internet Explorer, browsers and javascript simply are not allowed that level of access to the machine they run on, for obvious reasons.

I've seen a few scripts that purport to work using a Flash function as a proxy, but they don't work reliably either.

I'm sure that the vast majority of users are familiar with Ctrl+A, Ctrl+C, Ctrl+V these days.

If you only need to worry about IE or have control over the browser people will be using (intranet site) you can use the following as an example:

Code:

<html>
<head>



</head>
<body>

Copy the text below and paste into textbox:
<br />
<br />
<br />

This is some text with 16 digit credit card number
<br />
1111-2222-3333-4444 this is one format
<br />
and this is another format 1111 2222 3333 4444
<br />
and this one 1111222233334444 is yet another format
<br />

<textarea id="txtPaste" style="width: 400px; height: 400px;"></textarea>

<script type="text/javascript">



	var txtPaste = document.getElementById('txtPaste');

	txtPaste.onbeforepaste = function(){
		return false;
	};

	txtPaste.onpaste = function(){
			var clipboard = window.clipboardData.getData('Text');

			window.clipboardData.setData('Text', clipboard.replace(/\b(\d{4})([ -]*?)(\d{4})([ -]*?)(\d{4})([ -]*?)(\d{4})\b/gi, '\$1xxxxxxxx\$7'));
	};
</script>

</body>
</html>
