iOS 6 safari, setInterval doesn't get fired
提问by Johnny
It seems if I'm scrolling the window, the window.setIntervaldoesn't get attached / fired while the scrolling is happening or after. Has anyone else seen the same issue?
似乎如果我正在滚动window，window.setInterval在滚动发生时或之后不会被附加/触发。有没有其他人看到同样的问题？

iOS halts almost everything in response to user touch to guarantee it feels responsive. The setInterval issue is known, and there doesn't appear to be a workaround.
iOS 会停止几乎所有响应用户触摸的操作，以确保其响应灵敏。setInterval 问题是已知的，并且似乎没有解决方法。

During the "freeze" the timer will not catch up once the user releases the screen. The missed events are not deferred, but lost entirely (a bug).
在“冻结”期间，一旦用户释放屏幕，计时器将不会赶上。错过的事件不会被推迟，而是完全丢失（一个错误）。

I'm not completely sure, but you could use a setTimeoutinstead of setInterval? It's generally bad practice to use setInterval anyway.
我不完全确定，但您可以使用 asetTimeout代替setInterval? 无论如何，使用 setInterval 通常是不好的做法。
var delay = 100;
(function callee() {
setTimeout(callee, delay);
})();
