jquery asp.net combo box question

Question

Good Day,

I have a small form with a combo box (ASP.NET Drop Down List control) and a text box (with a DIV id txtName). When the selected index of the combo box changes, I want to clear out the text box.

I understand that:

$("#txtName").val(''); clears the text box value

The thing is the combo box. It contains a list of integers representing the months of the year. The drop down control is called ddlMonths.

$("#ddlMonths").change(function() {
    $("#txtName").val('');
});

I thought by using change, an onSelectedIndexChange event handler would be associated with this control.

I also tried (because I've ran into the client id being mangled in ASP.NET w/ jQuery) this:

$("#<%=ddlMonths.ClientID%>").change(function() {
    $("#<%=txtName.ClientID%>").val('');
});

and neither approach seems to be working. Am I missing something?

TIA,

coson

Answer 1

I just realized what my problem was!

The aforementioned code was in a javascript client block, but, I didn't have:

$(document).ready( function() {

// I put my code in here and then it worked.  My problem was more than likely that 
// my code executed *before* the controls were rendered, and I need to have the code 
// ready to execute *after* the document completely rendered.

});
