Changing Content Dynamically using JS/AJaX/JQuery

Hi there,

I am writing an application using JQuery that involves the user selecting an item from a dropdown. Once selected the content for that item is pulled from a DB using AJaX and other fields on the page are populated using the returned XML. The user then edits the content and clicks save.

I am having problems populating the FCKEditor fields dynamically. When using a simple textarea that is simple:

<script type="text/javascript">
   document.getElementById("myTextArea").value = "blah ... "
</script>

or

<script type="text/javascript">
   $("#myTextArea").val("blah ... ");
</script>

How do I do the same with an FCKEditor textarea?

Thanks in advance.
