js中
<script type="text/javascript">
            $(document).ready(function (e) {
                $("#Button2").click(function () {
                    if (confirm("确认要删除么！")) {
                        var all = $(".xuanzhong");
                        var code = "";
                        for (var i = ; i < all.length; i++) {
                            if (all.eq(i)[].checked) {

                                code += all.eq(i).val()+"|";
                            }
                        }
                        code = code.substring(, code.length - );
                        $.ajax({
                            url: "quanxuanshanchu.aspx",
                            type:"POST",
                            data: { ids:code },
                            datatype: "TEXT",
                            success: function (data) {
                                alert(data);
                                window.location.href = "gongyingshang.aspx";
                            }
                        });
                    }
                })

后台操作

  LXMallDBDataContext context = new LXMallDBDataContext();

        //取出Ajax传过来的值
        string uid = Request["ids"].ToString();
        string[] codes;
        codes = uid.Split('|');
        for (int i = ; i < codes.Length; i++)
        {
            Goods_Supplier data = context.Goods_Supplier.Where(r => r.ids == Convert.ToInt32(codes[i])).First();
            context.Goods_Supplier.DeleteOnSubmit(data);

        }
        context.SubmitChanges();
        Response.Write("删除成功！！！！！！");

        Response.End();
