How to get id of the inputTextArea(Rich) in the javascript on visualforce page?

I am trying to get id of the field in javscript like this :

var getRichTextId=document.getElementById('{!$Component.theForm.richTextArea}');  or 

 var getRichTextId= document.getElementById(richTextArea);

and the field on the same  VF page for getting id is :

 <apex:inputtextarea  id="richTextArea" richtext="true" cols="100" rows="15"/> .

But in both cases i am getting value of "getRichTextId" as null.How to get that.I want to copy some data into that field after getting id.
