很奇怪 - 我的ajax调用在IE中缓存,而它们在FF中正常运行;任何想法为什么?
function createRequestObject(){
var req;
if(window.XMLHttpRequest){
//For Firefox, Safari, Opera
req = new XMLHttpRequest();
}
else if(window.ActiveXObject){
//For IE 5+
req = new ActiveXObject("Microsoft.XMLHTTP");
}
else{
//Error for an old browser
alert('Your browser is not IE 5 or higher, or Firefox or Safari or Opera');
}
//alert (req);
return req;
}
//Make the XMLHttpRequest Object
var http = createRequestObject();
var head;
function sendRequestTwo(method, url, head1){
head = head1
if(method == "get" || method == "GET"){
http.open(method,url);
http.onreadystatechange = handleResponseTwo;
http.send(null);
}
}
function handleResponseTwo(){
if(http.readyState == 4 && http.status == 200){
var response = http.responseText;
if(response){
document.getElementById(head).innerHTML = response;
//window.scrollBy(0, 200);
}
}
}

我遇到了同样的问题。 IE可以非常缓慢。
尝试为您的网址添加时间戳:
url += '?ts=' + new Date().getTime();

IE积极地缓存ajax - 添加一个具有日期或其他独特之处的查询字符串,以防止它发生。
