Hey Experts!!

I have a super simple form that I'm just trying to get to serialize via Jquery.  There's only 2 values in this form: 1 is a select menu and the other is a hidden field with the date.

The date comes through fine, however the select menu always serializes as the first value regardless of what is selected.  Not sure what I'm doing wrong. My code is below:

Thanks in advance!

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

</head>

<body>
	<div id="container">
		<form name="ideaUpdate" method="post" id="ideaUpdate" action="">

			<div id="ideaDisplay">			
				<img src="images/lightbulb-logo.png" class="indicator" height="64px" />
				<h1>Just another test</h1>
								
					
					<div id="ideaText">

		   .fadeIn(500, function() {

		   });
		 }
		}); 
	});
    return false;
	});

move the line inside function


var dataString =  $('form#ideaUpdate').serialize();
	$(".submit").click(function() {

-->

	$(".submit").click(function() {
	var dataString =  $('form#ideaUpdate').serialize();

Thanks HainKurt.  Wow....something so simple.  Do you know why it has to be that way, other than it works?

your code runs when page is loaded, an that time the first one is selected

var dataString =  $('form#ideaUpdate').serialize();

always gets the first item since the selection not made yet... you make your selection but uses the data created when page is loaded...

So much of JavaScript code is event driven. You have to make sure that your code runs at the right time.

By the way, it's better to use a "submit" handler on the form instead of a "click" handler on the submit button.
