Question

我试图获取放置在转发器中的下拉列表的ID，以便进行一些ajax调用，但我不能这样做。我怎样才能使我的实现成为可能：

Ajax功能

function ShowCurrentTime() {
    $.ajax({
        type: "POST",
        url: "WebForm1.aspx/showColor",
        data: '{name: "' + $("#<%=colorList1.ClientID%>").val() + '" }',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: OnSuccess,
        failure: function (response) {
            alert(response.d);
        }
    });
}
function OnSuccess(response) {
    alert(response.d);
}

用户界面实施

<ajaxToolkit:TabPanel ID="TabPanel5" runat="server">
                <HeaderTemplate>Show Shoes</HeaderTemplate>
                <ContentTemplate runat="server">
                    <input id="btnGetTime" type="button" value="Show Current Time" onclick = "al()" />                                        
                    <asp:Repeater ID="shoeRepeater" OnItemCreated="shoeRepeater_ItemCreated" runat="server">
                        <HeaderTemplate></HeaderTemplate>
                        <ItemTemplate>

                            <table border="1" style="border-color:#ff9900; width:400px; font-weight:bold; font-family:'Oswald', Arial, sans-serif;">
                                <tr>
                                    <td rowspan="6" style="width:150px; height:150px;">
                                        <image src="shoeImages/<%#DataBinder.Eval(Container.DataItem,"ImagePath") %>"></image>
                                    </td>
                                </tr>
                                <tr>

在你的JS ajax函数中，

 var oObject= document.getElementById('colorList1');
 var id = oObject.id;

ASP.NET获取放置在转发器内的下拉列表的ID
