Implement AJAX encapsulation Sample sharing yourself

  This article mainly introduces its own implementation of AJAX encapsulation examples, need friends can refer to the following

The code is as follows:  //javascript object:ajax Object//created by Rexlee function Ajax (url,data) {    this.url=url; &nb Sp   This.data=data;     this.browser= (function () {         -if (Navigator.userAgent.indexOf ("MSIE") >0 {              return "MSIE";//ie browser      }else{  &NBSP ;         return "others";/Other    }} (); }; ajax.prototype={    Get:function () {        var result;         VAR xml http         if (this.browser== ' Msie ') {            try{                xmlhttp=new activexobject (' microsoft.xmlhttp ');                }catch (e) {                    xmlhttp=new ActiveXObject (' msxml2.xmlhttp ');       &nbsp                        }else{        & nbsp       xmlhttp=new XMLHttpRequest ();            };         xmlhttp.onreadystatechange=function () {            result = XMLH ttp.responsetext;//closures, cannot use this. Attribute        };         Xmlhttp.open (' Get ', this.url+ '? ') +this.data,false);//true cannot crawl data, why?         xmlhttp.send (null);         return result;    },     post:function () {        var result;         var xm Lhttp;         if (this.browser== ' Msie ') {            xmlhttp=new ActiveXObject ( ' Microsoft.XMLHTTP ');            }else{                Xmlhttp=new XMLHT TpRequest ();            };         xmlhttp.onreadystatechange=function () {            result = XMLH ttp.responsetext;//closures, cannot use this. Attribute        };         Xmlhttp.open (' POST ', this.url,false);//Must be set to false, otherwise unable to crawl responsetext         Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");//post, this must be         Xmlhttp.send (this.data);         return result;    }};  //var a=new Ajax (' Opp2.js ', '); Alert (' by Getn ' +a.get ())//alert (' by Postn ' +a.post ());       Window.onload=function () {document.getElementById ("btn"). Onclick=function () {    var P=document.getelementbyid ("T"). Value     var a=new Ajax ("phpoop/ Getpage.php "," page= "+p);     document.getElementById ("box"). Innerhtml=a.get ();    }; }
