I've been using a nice, elegant plugin called DropKick for my webapp http://jamielottering.github.com/DropKick/, and I seem to be having a slight issue with it and am not sure how to go about trying to fix it. I am trying to programmatically change the value of the select drop down menu. Below is a description of my issue, and a link to JSFiddle.
HTML:
<select id="start" class="timePreference">
<option value="Choose">Choose</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
</select>
jQuery:
$('.timePreference').dropkick();
$('#someDiv').click(function() {
$('#start').val("1");
alert($('#start').val());
);
When I show the value in alert, it shows as one, however when I look at the labels on the option it stays at the default or whatever it was prior to the change.
For example, if my default was "Choose" and I click someDiv, then alert will show "1", so it changing, but the select dropdown will still show "Choose". Any suggestions. I may just be missing something small, not sure.

-phew-
So, to start with I tried Change event [of dropkick] with in drop kick but its only for the change event within select and not from external element binding. i.e. in your case change button.
So; this is what I have done:
Explanation (if you interested)
I used firebug to inspect the variable and found that dropkick marshal your existing select with nice styling now when you used $('#timePreference option:selected').val("1");
dropkick actually did changed the selected value with in your element with id=timePreference but the div and ul and li styling
which is created by dropkick is not changed yet.
For the chosen span it has a class .dk_label
and for the current (green color) is given by .dk_option_current
class.
Please Note I pretty much read the plugin and figure out what is happening from here: https://github.com/JamieLottering/DropKick/blob/master/jquery.dropkick-1.0.0.js
If you wish to use firebug and see how elements are se use this link : http://jsfiddle.net/aNS9R/218/show/ and play around with your inspect mode, you will see dropkick styling and how it works.
JQuery code
$(document).ready(function() {
$('#timePreference').dropkick();
$('#go').click(function(){
// Assign slected option value to your select here -
// you can also make it something like this but your existing cdoe works anyways $("select_id option[value='3']").attr('selected','selected');
$('#timePreference').val("1");
//Now assign the select text value to the dropkick added element.
//If you will use firebug you can see the nice <div>, <ul> & <li> structure which morph your dropdown.
$('.dk_label').text(1);
// further if you want green color to be selected. class=dk_option_current does that
// You need to loop through the dropkick hierachy
$(".dk_options_inner li").each(function(){
$(this).removeAttr('class');
if ($(this).text() == "1"){
$(this).attr('class', 'dk_option_current');
}
});
});
});
Hope this helps you mate, cheers!
