---- setTimeout to detect changes in a text field

Now it works properly. But if I remove the if clause, the iframe gets updated every 10ms, no matter if there's a change in the textarea content or not. It is not necessary and CPU-friendly. The question is how can I set it to update the iframe only if there is a change in the textarea content?
