JQuery JCombo Select Per Another Select

Question

请在下面找到我用来输入用户从下拉列表中选择的多个选项的代码。问题是我需要做同样的事情，但使用jCombo下拉。此外，我需要计算驱动的组合名称，如sel1，sel2，sel3等。

请看一下代码，让我知道可以做些什么：（

<script type="text/javascript">    
$(document).ready(function() {
    $("#visitp").jCombo("getEmployees.php", { parent: "", selected_value : "<?php echo $employee_id;?>" } );
    $("#nparticipants").change(function(){

        // The easiest way is of course to delete all selectpar before adding new ones
        //$("#holder").html("");

        var count = $("#selectpar select").size();
        var requested = parseInt($("#nparticipants").val(),10);

        if (requested > count) {
            for(i=count; i<requested; i++) {
            var $ctrl = $('<select/>').attr({ type: 'text', name:'text', value:'text'});      
              //var $ctrl = $("#visitp").jCombo("getEmployees.php", { parent: "", selected_value : "<?php echo $employee_id;?>" } );    
                alert($ctrl);
                $("#selectpar").append($ctrl);
            }
        }
        else if (requested < count) {
            var x = requested - 1;
            $("#selectpar select:gt(" + x + ")").remove();
        }
    });
});
</script>
<form id="" action="" method="post">
<select id="nparticipants" name="nparticipants">
            <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>
</select>
<div id="selectpar"></div>
<select id="visitp" name="visitp"></select>        
<input type="submit" value="Go" />
</form>

伙计们，请让我知道eb可以做些什么：（
