其实有个问题你注意一下就是，改成POST 方式传就解决了
this.xmlHttp.open("POST", this.url, true);
//alert('end');
this.xmlHttp.setrequestheader("content-length",this._data.length);
this.xmlHttp.setrequestheader("content-type","application/x-www-form-urlencoded");
this.xmlHttp.onreadystatechange = Page;
this.xmlHttp.send(this._data);
