导读：一、前台代码 %@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"html xmlns="ht

一、前台代码

        $(function(){
            $.post("Default.aspx?action=getXML",function(xml){
                var trArr=[];
                $(xml).find("MatrixInfo").each(function(){
                    var id = $(this).find("ID").text();
                    var name = $(this).find("Name").text();
                    trArr.push("<tr><td>"+id+"</td><td>"+name+"</td></tr>");
                });
                $("#tbodyList").html(trArr.join(""));
