jquery 向下拉单添加选项问题 appendTo （新手问题，添加不上了）

JScript code


function AddOption(BuMen_Id, BuMen_Name) {

    var BuMen_ID = "";
    var BuMen_NAME = ""; 

    $("#BenXiaoZuoZhe_BuMen_0").empty();
    var html = "";
    for (var i = 0; i < BuMen_Id.length; i++) {

        BuMen_ID = BuMen_Id[i].substring(1, (BuMen_Id[i].length - 1));
        BuMen_NAME = BuMen_Name[i].substring(1, (BuMen_Name[i].length - 1));
        html += "<option value=\"" + BuMen_ID + "\">" + BuMen_NAME + "</option>";
    }
    $(html).appendTo("#BenXiaoZuoZhe_BuMen_0");
    
    alert(html);
}

以上是js代码，参数：BuMen_Id，BuMen_Name分别为传过来作为value和text的数组，
用for循环解析后，形成一个这样的字符串：

<option value="SD001T0501">软件工程系</option><option value="SD001T0502">计科系02</option><option value="SD001T0503">计科系03</option>

最后一句alert出的语句。

前台：

HTML code



 <td style="text-align: center">
             <select name="BenXiaoZuoZhe_BuMen_0" runat="server">
             </select>
  </td>

我试了很多次，
方法：document.form1.BenXiaoZuoZhe_BuMen_0.options.add(new Option(BuMen_ID, BuMen_NAME));没用，行不通。前台name改为id不行，前台用

HTML code

<asp:DropDownList ID="BenXiaoZuoZhe_BuMen_0" runat="server">
</asp:DropDownList>

也不行，大家帮我看看是哪个地方出了问题？？搞了一晚上了。。。

------解决方案--------------------
$(html).appendTo("#BenXiaoZuoZhe_BuMen_0");
前台需要的id没有，应该设置id，不是name
