Javascript页面自动刷新 [英] Javascript page auto refresh

问题描述

喜。可以帮上我这个javascript代码正确

hi. can sme on please help me to make this javascript code correct

<script type="text/javascript">
setTimeout('window.location.href=window.location.href;', 300000);
</script>

此代码将自动刷新页面300000毫秒，即5分钟。



所以我的页面包含如下所示

this code will refresh the page automatically in 300000 milliseconds which is 5 mins.

so my page contains like this below

<script type="text/javascript">
setTimeout('window.location.href=window.location.href;', 1080000);
</script>

<div id="norefresh">page refresh in 5 mins click "HERE" to not refresh</div>

所以我想在剩下1分钟时刷新id norefresh中的文本必须显示为取消页面刷新。谢谢。

so i want to make it when like 1 min left to refresh that text in id norefresh must be showing like that to cancel page refresh. thank you.

推荐答案

请看我对这个问题的评论。请在此处查看使用 setTimeout 的说明：

（只是忽略不活动时期的方面并显示鼠标/键盘绑定代码。）



完整的答案取决于刷新的目的;一般情况下，还有其他方法。通常，自动刷新是为了实现 pull技术，这是一件坏事，是由于缺少服务器推送。



请参阅我过去的答案和下面引用的文章：

Please see my comment to the question. Please see the explanation of the use of setTimeout here:
http://stackoverflow.com/questions/4644027/how-to-automatically-reload-a-page-after-a-given-period-of-inactivity[^].

(Just ignore the aspect of "period of inactivity" and the mouse/keyboard binding code shown.)

The full answer depends on the purpose of your refresh; in general case, there are other methods. Typically, auto refresh is done to implement pull technology, which is a bad thing, a result of the lack of server push.

See my past answer and the article referenced below:
