If you are using Ms Ajax:

function Blablabla(){

  var ctrl = $get('<%= TextBox1.ClientID %>');

}

If you are using jQuery:

function Blablabla(){

  var ctrl = $('#<%= TextBox1.ClientID %>');

}

but basically it is:

function Blablabla(){

  var ctrl = document.getElementById('<%= TextBox1.ClientID %>');

}

you may modify the html that is output by accessing the Response.Body or similar. I'm not remembering the exact name.

you can then put a piece of script to it:

Response.Body += "<script type=\"text/javascript\">";
Response.Body += "    PassVal(" + myControl + "," + myE + ");"
Response.Body += "</script>"

hope this helped you a bit. you have to look up the name of the property, don't got any VS here currently.
