来自 Ajax 的 Jquery 动态列表：选择选项不起作用

Question

我正在使用 ajax/jquery 加载商店列表，但是当用户选择商店时，它不会在页面刷新时保持选中该选项。它一直回到默认值（查看全部），我尝试用选项做 cfif 语句，但它似乎不起作用

HTML：

        <label for="LocationTypeID">Market:</label>
        <select id="LocationTypeID" name="LocationTypeID" class="ddRefreshFilters">
            <option value="-999">[ All Markets ]</option>
            <cfloop query="qUserLocationTypes">
                <option value="#qUserLocationTypes.LocationTypeID#" <cfif qUserLocationTypes.LocationTypeID IS Request.Attributes.LocationTypeID>selected</cfif>>#qUserLocationTypes.Name#</option>
            </cfloop>
        </select>
        
        <label for="Store_LocationID">Store:</label>
        <select id="Store_LocationID" name="Store_LocationID" class="ddRefreshFilters">
        </select>  

j查询：

<script>
    $(document).ready(function()
    {
      $('#LocationTypeID').change(function() 
        {
            var LocationTypeID = $(this).val();
            var Store_LocationID = $('#Store_LocationID').val();
          
            $.ajax({
             url: '/_scripts/ajax/listStores.cfm',
             type: 'post',
             data: {LocationTypeID:LocationTypeID},
             dataType: 'json',
                   
                    success: function(data)
                    {
                       var len = data.length;
                       $('#Store_LocationID').empty();
                       $('#Store_LocationID').append('<option value="-999">View All</option>');
                    
                       for( var i = 0; i<len; i++) {

                        var id = data[i]['locationid'];
                        var name = data[i]['name'];
                        
                        $('#Store_LocationID').append("<option value='"+id+"' <cfif Request.Attributes.Store_LocationID IS '"+id+"'>selected</cfif>>"+name+"</option>");
                       
                       }
                       
                    }
                }
            );
        });

        if ($('#LocationTypeID').val().length > 0)
        {
            $('#LocationTypeID').change();
        }

        $('.ddRefreshFilters').change(function()
        {
            var Store_LocationID = $('#Store_LocationID').val();
            var LocationTypeID = $('#LocationTypeID').val();
            var Url = '/dashboard/ss/StepTypeSummary.cfm?'&LocationTypeID=' + LocationTypeID + '&Store_LocationID=' + Store_LocationID;

            location.href = Url;
        });


    });
</script>
