Jquery Ajax解析XML数据(同步及异步调用)简单实例

$.ajax({
                async: true,// 默认true(异步请求)
                cache: true,// 默认true,设置为 false 将不会从浏览器缓存中加载请求信息。
                type: "POST",// 默认:GET 请求方式:[POST/GET]
                dataType: "xml",//默认["xml"/"html"] 返回数据类型:["xml" / "html" / "script" / "json" / "jsonp"]
                url: "Test.ashx",// 默认当前地址,发送请求的地址
                data: { key: "value" },// 发送到服务器的数据
                error: function(xml) { alert('Error loading XML document' + xml); },// 请求失败时调用
                timeout: 1000,// 设置请求超时时间
                success: function(xml) { // 请求成功后回调函数 参数：服务器返回数据,数据格式.
                    $("#users").empty();
                    // 用Jquery处理xml数据
                    $(xml).find('Table').each(function() {
                        var loginname = $(this).find("Loginname").text();
                        var Name").text();
                        $("#users").append("<li>" + loginname + " - " + name + "</li>");
                    });
                    /*
                    $(xml).find('user').each(function(i) {
                        var loginname = $(xml).find("user loginname").eq(i).text();
                        var user name").eq(i).text();
                        $("#users").append("<p>" + loginname + "</p>" + "<p>" + name + "</p><Br />");
                    })
                    $(xml).find("student").each(function(i){
                        var id"); //取对象
                        var id_value=$(this).children("id").text(); //取文本
                        alert(id_value);//这里就是ID的值了。
                        alert($(this).attr("email")); //这里能显示student下的email属性。

                        //最后输出了，这个是cssrain的写法，貌似比macnie更JQ一点
                        $('<li></li>').html(id_value).appendTo('ol');
                    });
