Adding a JavaScript 'Copy to Clipboard'

a way simpler way to access the clipboard...
copied=toCopy.createTextRange();
copied.execCommand("Copy");

This is all you need to do to copy text (from a text area, named toCopy in my example) to the clipboard

and how about the text from a java'edit zone ???????
Hi everybody. I'm new member here. I have the same trouble. I want to creat a "copy contents to clipboard" button. I saw all ur solution, but my problem is that the text I want to copy was created by a java's function (it's the script using for composing mails in Yahoo!Mail, you can format and add hyperlink to the text ). I knew how to get the text from the text area, but from that edit zone...... I have no idea. Can you help me??
And I want to check the text'length, too. Thank you!!!!
