js请求webservice服务

多的不说，先贴代码

function RequestWebService() {                try {var time1=new Date().getTime();//进行效能分析                    var domain = document.domain;//获取文档域名                    var URI = "http://" + domain + ":8082/Service1.asmx";//设定请求文档的路径                    var data="";//存储soap协议文档                    data = '<?xml version="1.0" encoding="utf-8"?>';                    data = data + '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">';                    data = data + '<soap12:Body>';                    data = data + '<HelloWorld xmlns="http://tempuri.org/" >';                    data = data + '<value>' + document.getElementById("a").value.trim() + '</value>';                    data = data + '</HelloWorld>';                    data = data + '</soap12:Body>';                    data = data + '</soap12:Envelope>';                    var xmlhttp;//构建ajax异步对象                    if (XMLHttpRequest) {                        xmlhttp = new XMLHttpRequest();                    }                    //xmlhttp.Open("POST", URL, false);                    xmlhttp.open("post", URI, false);//设定为非异步请求，post方法                    //xmlhttp.SetRequestHeader("Content-Type", "application/soap+xml");                    xmlhttp.setRequestHeader("Content-Type", "application/soap+xml");//设定请求头，内容类型为，SOAP+xml格式                    xmlhttp.send(data);//提交请求                    document.getElementById("data").innerHTML = xmlhttp.responseText;                    console.log(xmlhttp.responseText);var time2=new Date().getTime();//<span style="font-family: Arial, Helvetica, sans-serif;">进行效能分析</span><pre name="code" class="javascript"><span style="font-family: Arial, Helvetica, sans-serif;"><span style="white-space:pre"></span>console.log(time2-time1);//向控制台打印出所用时间</span>

} catch (er) { console.log(er.message); } }

实质上js请求webservice服务是一个post请求，使用jquery的post方法更为简单些。
