ajax调用是 html方向调用的， 而sqlconnection是 java代码调用的，本质差不多
1 <html>
2 <head>
3 <title>通过ajax调用webservice服务</title>
4 <script>
5 var xhr;
6 function sendAjaxWS(){
7 xhr = new ActiveXObject("Microsoft.XMLHTTP");
8 //指定ws的请求地址
9 var wsUrl = "http://192.168.1.108:5678/hello";
10 //手动构造请求体
11 var requestBody = ‘<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" ‘ +
12 ‘ xmlns:q0="http://service.itcast.cn/" xmlns:xsd="http://www.w3.org/2001/XMLSchema "‘+
13 ‘ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">‘+
14 ‘<soapenv:Body><q0:sayHello><arg0>‘+document.getElementById("msg").value+‘</arg0> <arg1>10</arg1> </q0:sayHello></soapenv:Body></soapenv:Envelope>‘;
15 //打开连接
16 xhr.open("POST",wsUrl,true);
17 //重新设置请求头
18 xhr.setRequestHeader("content-type","text/xml;charset=utf8");
19 //设置回调函数
20 xhr.onreadystatechange = _back;
21 //发送请求
22 xhr.send(requestBody);
23 }
24
25 //定义回调函数
26 function _back(){
27 if(xhr.readyState == 4){
28 if(xhr.status == 200){
29 var ret = xhr.responseXML;
30 //解析xml
31 var eles = ret.getElementsByTagName("return")[0];
32 alert(eles.text);
33 }
34 }
35 }
36 </script>

39 <input type="text" id="msg" />
