在客户端遍历datalist中的行?


//这是gridview的。但是datalist也是这样的。
<script>
function SelectAny(ck)
{
    if(ck.checked)
    {
        var gv = document.getElementById("GridView1");
        var rows = gv.getElementsByTagName("tr");
        for(var i =0;i<rows.length;i++)
        {
            var cid = rows[i].cells[0].getElementsByTagName("input");
            if(cid.length>0)
            {
                if(cid[0].type=="checkbox" && cid[0].id==ck.id)
                {
                    alert("你现在选中的是第"+i+"行!");
                }
            }
        }
    }
}
</script><body>
    <form id="form1" runat="server">
        <div>
            <asp:GridView ID="GridView1" runat="server"  >
                <Columns>
