Use the code below and add &nbsp;to your HTML source. This is for copy to clipboard. 
 
To open a popup somthing like: 
 
TextArea1 = document.getElementById(&quot;TextAreaID&quot;).value 
Newwin=window.open(TextArea1,'NewWin','toolbar=no,status=no,width=600,height=530') 
 
 

<pre><code class="code-10 nolinks" id="code-122614">function copyToClipboard(s)
{
	if( window.clipboardData &amp;&amp; clipboardData.setData )
	{
		clipboardData.setData(&quot;Text&quot;, s);
	}
	else
	{
		// You have to sign the code to enable this or allow the action in about:config by changing
		user_pref(&quot;signed.applets.codebase_principal_support&quot;, true);
		netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
 
		var clip Components.classes['@mozilla.org/widget/clipboard;[[[[1]]]]'].createInstance(Components.interfaces.nsIClipboard);
		if (!clip) return;
 
		// create a transferable
		var trans = Components.classes['@mozilla.org/widget/transferable;[[[[1]]]]'].createInstance(Components.interfaces.nsITransferable);
		if (!trans) return;
 
		// specify the data we wish to handle. Plaintext in this case.
		trans.addDataFlavor('text/unicode');
 
		// To get the data from the transferable we need two new objects
		var str = new Object();
		var len = new Object();
 
		var str = Components.classes[&quot;@mozilla.org/supports-string;[[[[1]]]]&quot;].createInstance(Components.interfaces.nsISupportsString);
 
		var copytext=meintext;
 
		str.data=copytext;
 
		trans.setTransferData(&quot;text/unicode&quot;,str,copytext.length*[[[[2]]]]);
 
		var clipid=Components.interfaces.nsIClipboard;
 
		if (!clip) return false;
 
		clip.setData(trans,null,clipid.kGlobalClipboard);	 
	}

Apparently, the only reliable way to do this is with flash.

<div class="content wysiwyg-content">
I thought it would be no problem finding a script to do this on the internet, but no luck so far. I have a textarea (called htmlcopy) and I want to put two links or buttons underneath it. One that says copy to clipboard (which copies it to the clipboard) and one that says preview (which open up a new window and displays the contents of the textarea). If anyone has either one of these, or can provide any assistance it is much appreciated. 
 
Thanks!
