Question

I’m have a problem with this code not working when it probably should be:

<script language = "javascript">
$(document).ready(function() {

$('#dept').change(
        function() {

            var datas = $(this).val();
            $.cookie("deptdata", datas);
            var urlDept = 'catch.cfm?dept=' + datas;
            $.ajax({
            type: 'post',
            url: urlDept,
            success: function(){
                 window.location.replace('');
                 var datasR = $.cookie("deptdata");
                 $("select#dept").val(datasR);
            }
             });
}); 

});

</script>

I have these included:

<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.8.2.custom.min.js"></script>
<script type="text/javascript" src="js/cookie.js"></script>
<script type="text/javascript" src="a_scripts.js"></script>

Form:

<form>
    <select name="DeptCode" id = "dept">
    <option value="NONE">Choose a Department
    <cfoutput query="getDepartments">
    <option value="#DeptCode#">#DeptName#</option>
    </cfoutput>
    </select>
    </form>
<cfoutput>#session.deptcode#</cfoutput>

What should be happening is: when a department is selected the page changes the session value via ajax (this works) to the one selected. However, I have to refresh the page for the query to work for another part of the page. So I wanted to cache the value of the select and reassign it to be selected after the page refreshes. (So it keeps the item selected).

You need to put the code to read the cookie outside the function

$(document).ready(function() { 

  var datasS = $.cookie("deptdata"); 
  $("select#dept").val(datasS);
