Javascript 从XMLHttpRequest更改responseText
我使用这段代码跟踪来自我的站点的所有ajax请求Javascript 从XMLHttpRequest更改responseText,javascript,ajax,Javascript,Ajax,我使用这段代码跟踪来自我的站点的所有ajax请求 XMLHttpRequest.prototype.uniqueID = function( ) { if (!this.uniqueIDMemo) { this.uniqueIDMemo = Math.floor(Math.random( ) * 1000); } return this.uniqueIDMemo; } XMLHttpRequest.prototype.oldOpen = XMLHttp

但它只能在火上工作,不能用ie或chrome
任何人都可以帮我解决这个问题,或者知道跟踪任何ajax请求的响应文本的另一种形式?在IE上,您应该使用
obj.attachEvent();
反而
obj.addEventListener();
你能在chrome或IE的调试控制台上发布你能看到什么吗?我不知道答案,但这很酷…Christian在IE和firebug lite中展示了[44]截获打开(post,,true,undefined,undefined)和停止。在FF[894]截获打开(POST,,true,undefined,undefined)[894]捕获发送(valor=Hello+H)POST 200 OK 289ms日志:[894]捕获:200 NOM:esto:Hello Hdyser,您不应该尝试编辑答案;以注释的形式输入您的注释(就像您那样),这是正确的方法。
