用Jquery訪問WebService并返回Json的代碼第2/3頁
更新時(shí)間：2008年09月15日 22:37:34 作者：
經(jīng)常會(huì)用JavaScript訪問asp.net的Webservice的需求，通常的方法是用asp.net ajax來解決，但asp.net ajax框架在不國內(nèi)并不經(jīng)常被使用。

復(fù)制代碼 代碼如下:

function WebService(url,callback,pars){

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")
}
});
}
