Internet Explorer刷新后不会更新AJAX处理的内容吗? [英] Internet Explorer won't update AJAX handled content on refresh?

问题描述

我有一个页面，该页面通过Jquery AJAX调用从XML文件中获取内容.

I have a page that grabs content from a XML file through a Jquery AJAX call.

问题在于，它将为除IE之外的所有浏览器刷新XML文件中的内容.

The problem is it will update the content from the XML file on a refresh for every browser except IE.

我试图通过元标记来解决这个问题

I have tried to solve this with meta tags

<meta http-equiv="expires" content="-1"/>
<meta http-equiv="cache-control" content="no-cache,must-revalidate" />
<meta http-equiv="pragma" content="no-cache"/>

这是相关javascript的一小部分

This is a small portion of the relevant javascript

$(document).ready(function(){ 
$.ajax({type: "GET",url: "file1.xml",dataType: "xml", success: parseXml });
}

function parseXml(xml){
document.getElementById(eventMonthName).innerHTML=firstxmlvari.getElementsByTagName('month')[0].childNodes[0].nodeValue;
}

任何建议将不胜感激！

推荐答案

是的，可能您遇到了IE的攻击性缓存...尝试设置HTTP标头，但对我有用的是将当前时间附加到查询字符串中，如下所示:

Yes, probably you run into IE's agressive caching... Try setting the HTTP headers, but something that works for me, is appending the current time to the query string like this:

$(document).ready(function() {
    $.ajax({
        type: "GET",
        url: "/echo/xml/",
        data: {
            _rnd: new Date().getTime()
        },
        dataType: "xml",
        success: parseXml
    });
});

function parseXml(xml) {
    alert(xml);
}

关于JSFIDDLE的示例: http://jsfiddle.net/WVBDc/，检查传出的HTTP请求
