Here a basic example
这是一个基本的例子
(function(seconds) {
var refresh,
intvrefresh = function() {
clearInterval(refresh);
refresh = setTimeout(function() {
location.href = location.href;
}, seconds * 1000);
};
$(document).on('keypress click', function() { intvrefresh() });
intvrefresh();
}(15)); // define here seconds
This will refresh the page every 15 seconds without a keypress or a click event (but if you have same events defined elsewhere making a stopPropagation()this won't properly work because the event won't be able to reach the element)
这将在没有按键或点击事件的情况下每 15 秒刷新一次页面（但如果您在其他地方定义了相同的事件，stopPropagation()这将无法正常工作，因为该事件将无法到达该元素）
回答by Alnitak
Create a timer (setTimeout) that will refresh the page, and every time there's a key press or mouse press, just restart the timer.
创建一个setTimeout将刷新页面的计时器 ( )，每次有按键或鼠标按下时，只需重新启动计时器。
See this questionfor code that does most of what you want.
请参阅此问题以了解执行您想要的大部分内容的代码。
FWIW, here's F.Calderan's answer rewritten to:
FWIW，这是 F.Calderan 的答案改写为：
- eliminate unnecessary closures
- separate the actionfrom the repetition, by suppling the action as a callback
- 消除不必要的关闭
- 分离作用从所述重复，通过suppling动作作为回调

function setIdle(cb, seconds) {
var timer;
? ? var interval = seconds * 1000;
function refresh() {
? ? ? ? ? ? clearInterval(timer);
? ? ? ? ? timer = setTimeout(cb, interval);

}
setIdle(function() {
location.href = location.href;
}, 15);
