//增加一个POST或GET键值对 this.AddKey = function(skey,svalue){


偶尔一笔

三 xmldom 的使用方法
IE7, Mozilla ,Firefox等浏览器中 javascript是内置有 XMLHttpRequest 这个对象的 但IE5+则没有 需要用如下方法来启动 takko fashion //IE 6 try{ xhttp = new ActiveXObject("Msxml2.XMLHTTP";} catch(e){ ; } //IE5+ if(xhttp takko fashion == null) try { xhttp = new ActiveXObject("Microsoft.XMLHTTP";} catch(e){ ; }
参数三 true 表示异步传输 服务器返回信息完成前 你可以进行其它操作 false 表示阻断方式的传输
[1] 如果用阻断的方式来发送请求 那么直接用 if(xhttp.readyState == 4)就能判断是否完成
xhttp.onreadystatechange = function() {     //这里来进行上面阻断方式的判断     if(myajax.xhttp.readyState == 4){                       takko fashion   takko fashion       if(myajax.xhttp.status == 200){                                   //要进行的后续操作                               }       takko fashion         } }
//初始化xmlhttp if(window.XMLHttpRequest){//IE7, Mozilla ,Firefox 等浏览器内置该对象         this.xhttp = new XMLHttpRequest(); }else if(window.ActiveXObject){//IE6 IE5         try { this.xhttp = new ActiveXObject("Msxml2.XMLHTTP");} catch (e) { }         if (this.xhttp == null) try { this.xhttp = new ActiveXObject("Microsoft.XMLHTTP");} catch (e) { } } this.xhttp.onreadystatechange takko fashion = WiteOKFunc; //rs: responseBody responseStream responseXml responseText
//初始化xmldom this.InitXDom = function(){   var obj = null;   if (typeof(DOMParser) != "undefined") takko fashion { // Gecko Mozilla Firefox       var parser = new DOMParser();       obj = parser.parseFromString(xmlText, "text/xml");   } else { // IE       try { obj = new ActiveXObject("MSXML2.DOMDocument");} catch (e) { }       if (obj == null) try { obj = new ActiveXObject("Microsoft.XMLDOM"); } catch (e) { }   }   this.xdom = obj; };
//增加一个POST或GET键值对 this.AddKey = function(skey,svalue){               this.keyCount++;               this.keys[this.keyCount] = skey;               this.values[this.keyCount] = escape(svalue); };
//增加一个Http请求头键值对 this.AddHead = function(skey,svalue){               this.rkeyCount++;               this.rkeys[this.rkeyCount] = skey;           takko fashion     this.rvalues[this.rkeyCount] = svalue; };
//清除当前对象的哈希表参数 this.ClearSet = function(){               this.keyCount = -1;       takko fashion         takko fashion this.keys = Array();               this.values = Array();               this.rkeyCount = -1;               this.rkeys = Array();               this.rvalues = Array(); };
//发送http请求头 this.SendHead = function(){               if(this.rkeyCount!=-1){ //发送用户自行设定的请求头               takko fashion     for(;i<=this.rkeyCount;i++){                                   this.xhttp.setRequestHeader(this.rkeys[i],this.rvalues[i]);                   }   } if(this.rtype=='binary'){                   this.xhttp.setRequestHeader("Content-Type","multipart/form-data");   }else{                   this.xhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");   } };
//用Post方式发送数据 this.SendPost = function(purl){               var pdata = "";       takko fashion         var i=0;               this.state = 0;               this.xhttp.open("POST", purl, true);               this.SendHead();   if(this.keyCount!=-1){ //post数据                   for(;i<=this.keyCount;i++){ takko fashion                                   if(pdata=="") pdata = this.keys[i]+'='+this.values[i];                               takko fashion     else pdata += "&"+this.keys[i]+'='+this.values[i];                   }   }   this.xhttp.send(pdata); };
//用GET方式发送数据 this.SendGet = function(purl){             takko fashion   var gkey = "";       &n
