Greasemonkey script to reload the page every minute
提问by John Smith
How to reload a page every 60 seconds?
如何每 60 秒重新加载一个页面？
My attempt:
我的尝试：
setTimeout (location.reload, 1 * 60 * 60);
I'm not sure what those numbers mean, or how to adapt them to reload after 60 seconds only.
我不确定这些数字是什么意思，或者如何使它们仅在 60 秒后重新加载。

setTimeout(function(){ location.reload(); }, 60*1000);
You have to pass a full function as first argument, and second is the time in millisecond. So in your case, 60 * 1000
你必须传递一个完整的函数作为第一个参数，第二个是以毫秒为单位的时间。所以在你的情况下，60 * 1000

You may give a function name, since it is a callable, however, location.reloadis a method of the locationobject. It is callable, but when it is executed by the timer, the thiscontext will not be the location object. This fact leads to an error.
你可以给一个函数名，因为它是一个可调用的，但是，它是对象的location.reload一个方法location。它是可调用的，但是当它被定时器执行时，this上下文将不是位置对象。这个事实会导致错误。
The solutions are:
Write a simple anonymous function as a wrapper as already described in the accepted answer or
create a bound function of the reload method with locationas its thiscontext:
解决方案是：
编写一个简单的匿名函数作为包装器，如已接受的答案中所述，或者
创建一个 reload 方法的绑定函数location作为其this上下文：
setTimeout(location.reload.bind(location), 60000);

Looking at a documentationmight help you. The parameters to the setTimeout function are the action which is performed and the number of milliseconds until this happens. 1 * 60 * 60is 3600ms or 3.6 seconds. A timespan of 60 seconds would be 60000.
查看文档可能对您有所帮助。setTimeout 函数的参数是执行的操作以及执行此操作之前的毫秒数。1 * 60 * 60是 3600 毫秒或 3.6 秒。60 秒的时间跨度将是 60000。
