In a section in the <head> tags of my document I have code that lets me use the Id of my asp.net control from JavaScript like this:
<script language="javascript" type="text/javascript">
var customerId = '<%= Me.CustomerTextbox.ClientID %>';
</script>
However, if I want to modify the page structure in later stages of the page life cycle, it give me an error because I have the ASP tags in there. A work-around is enclosing the ASP tags in a server control like this:
<div id="customerIdContainer" runat="server">
<script language="javascript" type="text/javascript">
var customerId = '<%= Me.CustomerTextbox.ClientID %>';
</script>
</div>
But then I get a warning that a div tag is not allowed in the head tag. So is there a container tag that is valid in the head that I can add runat="server" to to make it a server control so I can workaround this problem without the warnings?
