I'm trying to fire an ajax event, and passing the value of select list options as arguments in the ajax call. Unfortunately, I'm firing the call on the .change event, and it is passing the values of the select option before the new option has been selected (i.e passing the previously selected options values). Is there an event which will get the current values of the option selected? Much thanks in advance,
<select id='theList'>
<option> Option 1</option>
<option> Option 2</option>
</select>
In the JS:
$('#theList').change( function() {
$.getJSON('Home/MethodName', { var1: Option1Value, var2: MiscValue}, function(data) {
//Execute instructions here
}
)});
I wanted to use .trigger, but I think that fires beforehand as well.

A word of warning, .change
is now defunct, you should use...
.on('change', function()
Like that.

You must be doing something wrong when getting the current select value. The following works correctly for me.
<select id="demo">
<option value=""></option>
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
</select>
$("#demo").change(function() {
alert("current select value " + $(this).val());
});

I think .change() is what you want, but you're misusing it. The change event fires after the value has changed. In your handler, you need to read the new value:
$('#theList').change( function() {
var value = $('#theList').val();
$.getJSON('Home/MethodName', { your_key: value }, function(data) {
// ...
}
)});
You also might want to set values on your <option>
tags:
<option value="something"> Option 2</option>
