setInterval pauses in iphone/ipad (mobile Safari) during scrolling
提问by user1478076
I use the setInterval function in a website, and it works fine in IE, Chrome, Firefox and Safari. When i try it on ipad/iphone (safari mobile) i get problem: if i scroll the screen, the setInterval function pauses and it resumes only when i stop scrolling!
我在网站中使用 setInterval 函数，它在 IE、Chrome、Firefox 和 Safari 中运行良好。当我在 ipad/iphone（safari mobile）上尝试时，我遇到问题：如果我滚动屏幕，setInterval 函数会暂停，只有当我停止滚动时它才会恢复！
is there a way to prevent the function from pausing? Thanks

I'm afraid no, there's no way to prevent such behaviour. There's a plenty of topics here in SO about this problem (more-o-less related), here's a particularly interesting one. Its summary is simple:
恐怕不，没有办法阻止这种行为。这里有很多关于这个问题的主题（更多相关），这里有一个特别有趣的主题。它的总结很简单：
iOS elastic scroll can't be tracked. There's no event listener for it + both timeout / interval doesn't execute during scroll. And because there's no requestAnimationFrame in iOS5, this seems impossible to solve.
无法跟踪 iOS 弹性滚动。它没有事件侦听器 + 滚动期间不执行超时/间隔。而且由于iOS5中没有requestAnimationFrame，这似乎无法解决。
