function AjaxGet(URL) {
var xmlhttp = createXMLHttps();
xmlhttp.open("Get",URL,true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status==404) {$("Loading").innerHTML=&#39;读取页面失败,文件&#39;+URL+&#39;不存在!&#39;;return}
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
