用.net 处理xmlHttp发送异步请求_ASP.NET技巧

}

this.req.send(params);

}catch (err){

this.onerror.call(this);

}

}

}

net.xmlHttp.onReadyState=function(){

var req=this.req;

var ready=req.readyState;

if (ready==net.READY_STATE_COMPLETE){

var httpStatus=req.status;

if (httpStatus==200 || httpStatus==0){

this.onload.call(this);

}else{

this.onerror.call(this);

}

}

}

net.xmlHttp.prototype.defaultError=function(){

alert("error fetching data!"

+"\n\nreadyState:"+this.req.readyState

+"\nstatus: "+this.req.status

+"\nheaders: "+this.req.getAllResponseHeaders());

}

下面开始写发送xmlHttp请求的代码：

default.js

//全局xmlHttp对象

var cobj;

/**//* Post begin*/

//绑定Post发送xmlHttp事件到btnTestPost

function loadTestPost()

{

var iobj = document.getElementById("btnTestPost");

//btnTestPost按钮监听的绑定

var clickRouter=new jsEvent.EventRouter(iobj,"onclick");

clickRouter.addListener(btnTestPostClick);

}

function btnTestPostClick()

{ // open参数 url, onload, params, method, contentType, onerror

cobj = new net.xmlHttp("DefaultHandler.ashx",dealResult, "<T/>", "POST");

}

/**//* Post end*/

/**//* Get begin*/

//绑定Get发送xmlHttp事件到btnTestGet

function loadTestGet()

{

var iobj = document.getElementById("btnTestGet");

//btnTestGet按钮监听的绑定
