How to get the Instance of TextArea

trying to figure out how to do this in a masterpage also.

i found that when the masterpage is rendered it changes the id of everything inside of the content tag.

Mine is this in code

<textarea runat="server" cols="80" id="editor1" name="editor1" rows="10">

but it renders like this

<textarea name="ctl00$ContentPlaceHolder1$editor1" id="ctl00_ContentPlaceHolder1_editor1" cols="80" rows="10">

Does anyone know how to get around this issue with .net?

okay i found out that by adding the runat="server" tag it changes my id field. Once i removed this and also add the java script to the header and in the contact tag it started working. Now i just need to figure out how to access the content in the text area.
