I'm not certain I understand what you're asking, but I'll take a guess. You
need the client ID an html element that asp.net generates, correct? There
is a .ClientID property that will expose that. So, you have to pull that
client ID from your code behind and inject it into your client-side code in
someway. You can build strings in your codebehind containing javascript
functions, but I personally find this to be a PITA. So, I use a Literal
that's hidden and put my client-side code in there, alter it as needed, and
then register the text of it. This makes for a better Visual Studio
experience. Here's a sample:
codebehind:
protected void Page_Load(object sender, EventArgs e)
{
litClientScript.Text = litClientScript.Text.Replace("%someTextBox%",
someTextBox.ClientID);
Page.RegisterClientScriptBlock("JS", litClientScript.Text);
}
..aspx:
<asp:textbox id="someTextBox" runat="server" text="here's some text" />
<input type="button" onclick="giveIt();" value="Click me" />
<asp:literal id="litClientScript" runat="server" visible="false">
<script type="text/javascript">
function giveIt() {
alert(document.getElementById('%someTextBox%').val ue);
}
</script>
</asp:literal>
