jQuery: detect pasting into a WYSIWYG editor

I'm using htmlarea for my little CMS, and I was wondering if it's possible to d开发者_如何学Goetect if something gets pasted into it with jQuery?

Try adding an Event Listener to your textarea for "keydown," and then looking out for keyCode == 86, that's the paste event. Now you can do whatever you want to happen when a user tries to paste.

Like this:

document.getElementById('YOURhtmlArea').addEventListener('keydown', 
function (foo)
{
     if (foo.keyCode == 86)
     {
          alert('SOMEONE IS PASTING');
          foo.preventDefault();
     }
});

I hope that helps.
