Try the following in your JavaScript:

if(tinyMCE.get("chatContent_field").getContent()==''){
   alert("Please enter the text.");
   return false;
}

where "chatContent_field" is id of your text area.

The editor should put its content in the textarea it's installed upon, but it might do it after You check. Try using firebug to see what Your editor does to the textarea it covers.

If You want to check directly You have to find the iframe within the editor and access its content.
