  XMLHttpReq.onreadystatechange = processResponse;//指定響應函數
  XMLHttpReq.send(null);  // 發送請求
}
// 處理返回資訊函數
    function processResponse() {

         if (XMLHttpReq.status == 200) { // 資訊已經成功返回，開始處理資訊
    DisplayHot();
    setTimeout("sendRequest()", 1000);
            } else { //頁面不正常
                window.alert("您所請求的頁面有異常。");
            }
