<p>I have some problems sending an id though jquery. 
I have a form select with some values, i want to "grap" the id when change option selection. </p>

<pre><code>&lt;select name="case_name" id="case_id"&gt;
            &lt;option value="10009" &gt;Case 1&lt;/option&gt;
            &lt;option value="10010" &gt;Case 2&lt;/option&gt;
            &lt;option value="10011" &gt;Case 3&lt;/option&gt;

    var PARAMS = { "case_id": 10009 }; 

$("#case_id").change(function() {  
    var CASE_ID = $(this).val();
    var PARAMS = { "case_id": CASE_ID };
    alert(CASE_ID);
});
