我写道:内存泄漏在一个包裹的XMLHttpRequest功能
function ao(){
this.count=0;
this.flag=0;
this.tmr=0;
var self = this;
this.make=function(){
//log("before: "+this.url+" "+this.xhr);
self.xhr = (window.XMLHttpRequest)
? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
//log("after: "+this.xhr);
}
this.request = function (method, url, sendStr, delay){
this.delay=delay;
if(delay && self.tmr==0){
self.start();
}
if(self.flag==0){
this.method = method;
this.url = url;
this.sendStr = sendStr;
self.make();
this.xhr.open(method, url, true);
this.xhr.onreadystatechange = this.stateChange;
this.xhr.onabort=this.rrr;
this.xhr.onerror=this.rrr;
this.xhr.setRequestHeader("Cache-Control","no-cache");
this.xhr.send(sendStr);
}
};
this.repeat=function(){
if(this.flag==0){
this.flag=1;
this.count++;
this.xhr.open(self.method, self.url+"?"+this.count, true);
this.xhr.onreadystatechange = this.stateChange;
this.xhr.onabort=this.rrr;
this.xhr.onerror=this.rrr;
this.xhr.setRequestHeader("Cache-Control","no-cache");
this.xhr.send(self.sendStr);
}
return 0;
}
this.stop=function(){
window.clearInterval(this.tmr);
this.tmr=0;
this.flag=0;
}
this.start =function(){
self.tmr=window.setInterval(function(){self.repeat();},self.delay);
}
this.stateChange = function(){
if (self.xhr.readyState <= 1){
return;
self.log("404 errors");
} else {
if (self.xhr.readyState == 4 && self.xhr.status == 200){
self.resp = self.xhr.responseText;
if (self.callback != null)
self.callback(self.xhr.readyState, self.xhr.status);
else {
if (self.getHTML) {
self.getHTML(self.resp);
this.xhr=null;

和窗户FF有内存泄漏。我花了好几天的时间来修复它,但我很难过。
以下工作:
var x=new ao();
ao.request("POST","/cgi-bin/sdf.cgi","text",1000)
,每1000毫秒,如果前一个请求完成后,它使新的要求。
那么是什么问题? –
它在Firefox中有内存泄漏 – request
你是如何确定它泄漏内存的? –
