test.html

复制代码 代码如下:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>untitled page</title>
<script src="jquery-1.2.2.js" type="text/javascript"></script>
</head>
<body>

<input type="button" onclick="requesthelloworld();" value="请求helloworld" />
<input type="button" onclick="requestcreateuser();" value="请求createuser" />
<script type="text/javascript">


function requesthelloworld(){
webservice('ws1.asmx/helloworld',function(obj){alert(obj);});
}

function requestcreateuser(){
webservice('ws1.asmx/createuser',function(obj){alert(obj.name);},'{name:"林子",age:25}');
}


function webservice(url,callback,pars){
$.ajax({
data:pars,
url: url,
type: "post",
contenttype: "application/json;utf-8",
datatype:'json',
cache: false,
success: function(json){
callback(json.d);
},
error:function(xml,status){
if(status=='error'){
try{
var json = eval('(' + xml.responsetext + ')');
alert(json.message+'\n'+json.stacktrace);
}catch(e){}
}else{
alert(status);
}
},
beforesend:function(xml){
if(!pars) xml.setrequestheader("content-type", "application/json;utf-8")
}
});
}
</script>
</body>
</html>

web.config为vs2008在.net 3.5状态下创建的默认的 也有很重要的作用 这里贴出来
复制代码 代码如下:
