Question

I’m very new in .net c#, just a question here to about the following code. I have wrote a code to display a text box on the screen as below:

  <asp:TextBox ID="sUnit" runat="server" MaxLength="12" Width="3em" /> 

But somehow I failed to using jqueryto assign a value into this textbox:

 $('#sUnit').val('test');

Surprisingly when I view the source code, and it show me the ID for the text box is like below:

<input name="ctl00$cplh$sUnit" type="text" maxlength="12" id="ctl00_cplh_sUnit" style="width:3em;" />

Does anyone know how can I get the textbox ID so that I can assigned the value into the textbox?

Hope my question is not sound stupid.

If you are using ASP.NET 4.0, set the ClientIDMode to static.

For older versions, use
$('#<%= sUnit.ClientID %>')
