后台如何循环前台动态添加的div里的元素

     $(".menutd").click(function () {
                // alert("asasas");
                //alert(receiveNames.val());
                var phone = $(this).children("input").eq(0).val(); //号码
                var addressInfoId = $(this).children("input").eq(1).val(); //id
                var name = $(this).children("span").html(); //姓名
                //alert("id为：" + addressInfoId + ",姓名：" + name + ",号码：" + phone);

                //var oldphones = "";
                if ($.trim(divReceiveUsers.html()).length != 0) {
                    for (var i = 0; i < $(".moblie").length; i++) {
                        if (phone == $(".moblie").eq(i).attr("id")) {
                            return;
                        }
                    }
                    //alert(oldphones);
                }
                var item = "<div class=\"item\"><span id='" + phone + "' class=\"moblie\" name=\"moblie\" runat=\"server\">" + name + "</span><img class=\"imgDel\" src=\"images/12-em-cross.png\" alt=\"删除\"/></div>"; // onclick=\"deleteName(this)\" 
                //alert(item);
                divReceiveUsers.append(item);
            });
