ScriptManager控件内的 <services>标记包含页面所调用的webservice的文件名称。如下
<services>
<atlas:servicereference path="~/HelloWorldService.asmx" />
</services>
然后通过javascript脚本调用这个web服务，
function DoSearch()
{
var SrchElem = document.getElementById("SearchKey");//得到id名位SearchKey的html元素
Samples.AspNet.HelloWorldService.HelloWorld(SrchElem.value, OnRequestComplete);
//DoSearch方法调用远程的web服务的HelloWorld方法，将SerchElem.Value指HelloWorld的参数，OnRequestComplete指本地的回调函数。首先调用HelloWorld方法，挥发后将返回值作为参数传递给OnRequestComplete方法...
HelloWorld的函数定义为
[WebMethod]
string HelloWorld(string str)
{
/////.....code herer
return "sfsdfsdfdsf";
}
}
function OnRequestComplete(result)
{
var RsltElem = document.getElementById("Results");
RsltElem.innerHTML = result;
}
