缓存在我的小工具中，如何将其删除? [英] Cache in my gadget, how delete it?

问题描述

大家好！
我的名字叫KỳNguyễn，我来自越南，我有一个问题想问您我的申请.能帮我吗?
我在做一个小工具，当系统在屏幕上启动时，它将显示我公司的新员工.
但我不知道为什么我的小工具具有缓存，因此xmlhttp对象返回失败值，它在系统中返回旧值，您可以看到以下内容:

hello everybody!
My name is Kỳ Nguyễn, I come from VietNam, and I having a problem want to ask you for my application.Can you help me, please?
I doing a gadget, it will display new job of staff in my company when system start on screen.
but I don''t know why my gadget have cache, so xmlhttp Object return fail value, it return old value in system, You can see following:

this.xmlHttp = CreateXmlHttpRequestObject();
                 searchTags  = System.Gadget.Settings.read("Tags");
                     if (searchTags=='') {
                     searchTags="admin";
                           }
this.xmlHttp.open("GET", "http:localhost/gadget/GetData?value=" + searchTags,false);
this.xmlHttp.setRequestHeader("Cache-Control","no-cache"); //(*)
               this.xmlHttp.send();
           var temp = eval("(" + this.xmlHttp.responseText + ")");
                   job.innerHTML = temp.d;

我已经调试，看到它运行到(*)，但是this.xmlHttp.send()返回了旧值.

I have debugged, see it run true to (*), but this.xmlHttp.send() return old value.
Can you help me this error, Please?

推荐答案

我不确定您的问题，是否因为相同的搜索标签得到的结果相同?
无论如何，在AJAX中，我通常通过在我的http请求中添加时间戳作为伪查询参数来解决缓存问题，也可以尝试如下操作:

I am not sure about your problem, is it that you getting same result for same search tag?
Anyways, in AJAX i generally fix the caching problem by adding a timestamp as a fake query parameter in my http request, you can also try something like below:

<br />
var currentTime = new Date();<br />
this.xmlHttp.open("GET", "http:localhost/gadget/GetData?time="+currentTime.getTime()+"&value=" + searchTags,false);<br />

这会有所不同.每次都要求.

看看是否适合您.

this will diff. request every time.

see if that works for you.
