如何更新从JavaScript元刷新使用异步调用的时候？ [英] How can I update meta refresh from javascript when using asynchronous calls?

问题描述

我有一个使用元刷新到注销页面，空闲用户后清理系统。 （别担心，服务器也超时会话）

I have a system that uses a meta refresh to a logout page, which cleans up after idle users. (Don't worry, the server also times out the session)

我开始通过AJAX做一些操作（不是真正的XML，但那是题外话）。我可以运行的异步请求返回的JavaScript，所以我不知道是否有可能重新设置元刷新的页面上，这样它有更长的超时。通常的setTimeout调用只需添加一个新的超时，但不会取代元超时？

I started doing some operations via ajax (not really xml, but that's beside the point). I can run javascript returned from the async request, so I'm wondering if it's possible to reset the meta refresh on the page so that it has a longer timeout. The usual setTimeout calls just add a new timeout, but do they replace the meta timeout?

推荐答案

没有。 meta标签是PTED加载页面时，就好像是一个实际的HTTP头，和负荷的变化上不会产生任何影响跨$ P $。

No. The meta tag is interpreted when the page loads as though it were an actual HTTP header, and post-load changes have no affect on it.

你最好开沟元刷新，并完全依赖于JavaScript在适当的时候重新加载页面。如果你必须支持的客户端没有脚本，然后默认为使用元刷新结合JS无脚本页面重定向到启用脚本（元刷新免费）页面谁可以利用它的用户。

You're better off ditching the meta refresh, and relying entirely on JavaScript to reload the page when appropriate. If you must support clients without scripting, then default to a no-script page utilizing meta refresh combined with a JS redirect to script-enabled (meta refresh free) page for users who can take advantage of it.
