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 the follow clears the text box value:
$("#txtName").val('');
T开发者_C百科he 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?
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.
});
