The following does not work:
var EtxtDOB = $get('<%=FormView1.FindControl("frmEditPerson").FindControl("EtxtDOB").ClientID %>');
How can I find this nested control in javascript?

2doesn't work. I believe $get and getElementById are close to the same. Although I've seen getelementID work and $get not work on occasion. I believe $get allows just server controls. i can totally be wrong though.

It won't work unless you replace 'EtxtDOB' with the *ID* of your control. If it is a dynamically generated ID then you need to use code of the form "David" provided you in the comments to your question.

$get() is part of the ASP.NET AJAX js and defined as a shortcut to document.getElementById() - so you have to reference that .js file to use it, I think the ScriptManager also causes it to be included.

A:
I find it's a lot clearer code-wise to explicitly emit the IDs of the controls you want to access via Javascript in the page's code-behind. Something like:
Page.RegisterClientScriptBlock("clientIDs", "var myControlID = '" + myControl.ClientID + "';");
Then you can access this anywhere in your client-side script and it's a lot cleaner:
var ExtODB = getElementById(myControlID);
If you want to get fancy create a utility function that does this for you... or create a custom attribute that automatically does this.
