Hey guys!

I need to handle the change event, when the textarea of CE gets an input (keydown).  A flag should be set and triggers a notification which informs the user about unsaved changes.

I found the follwing code snippets, but they dont work for me. I dont know why. Or  do i misuse it?

editor.ID = "rtfDocumentEditor"

function CuteEditor_OnChange(rtfDocumentEditor) {

      checkIsDirty();  

}

var rtfDocumentEditor = document.getElementById("<% = rtfDocumentEditor.ClientID %>"); 

function checkIsDirty() { 

      if (rtfDocumentEditor.IsDirty() == true) {

            alert("Unsaved Changes");

      }

}
