Interacting with ASP.NET properties in Javascript

Question

I am try in to get the ClientID of one of my server controls to appear in a Javascript in my aspx page.

Obviously I am going about it the wrong way, but my intent should be made clear in the following:

doSomethingFirst();
var hid = "<% Response.Write(HidingField.ClientID) %>";
doSomethingElse(hid);

Any advice?

Thanks.

are you saying that this didn't work? If you put in a Javascript alert and pass it hid after you set it what comes up? — jaltiere

I'm doing a bit of guessing about your intent, so forgive me if I've guessed wrong, but I think this is what you're looking for:

doSomethingFirst();
var hid = document.getElementById('<%= HidingField.ClientID %>');
doSomethingElse(hid);

I assuming your intent is to get a reference to the DOM element represented by the client id so that you can then do some sort of javascript operation on that element.

Have you tried:

var hid = "<%= HidingField.ClientID %>";

making sure that "HidingField" is the ID of the server control?

<% Response.Write(HidingField.ClientID) %>'s kinda equivalent so I guess the OP has already tried this.

It was the stupid missing semicolon.

I apologized for wasting everyone's time.
