How to preload a div combobox in jquery
<p>I have code as follows:</p>

<pre><code>$("#item_select").change(function() 
{ 
    var params = $("#item_select option:selected").val();
    $.post('/account/ar_form.php', {idata: params},  function(data){
        $("#message_display" ).html(data);
    });
}); 
</code></pre>

<p>This is a dropdown that uses /account/ar_form.php to display html in the div correctly.</p>

<p>But it only displays on the change event.  I'd like it to preload the data.  When I use a load event, it will display the html, but on change, it displays it twice.</p>
