更改setInterval的间隔 [英] Change interval of setInterval

问题描述

有没有办法在运行时修改setInterval的函数调用间隔，除了删除它（clearInterval）并再次使用不同的值恢复？

Is there a way of modifying the interval of calls of function set with setInterval during runtime, other than removing it (clearInterval) and reinstating again with a different value?

推荐答案

使用setTimeout，另外这是async JS的非阻塞方法：

Use setTimeout instead, additionally this a non-blocking method for async JS:

var interval = 1000;

function callback() {
   console.log( 'callback!' );
   interval -= 100; // actually this will kill your browser when goes to 0, but shows the idea
   setTimeout( callback, interval );
}

setTimeout( callback, interval );

不要使用 setInterval ，如有些情况（很多 setInterval +长回调，通常比超时长），由于队列大小有限，浏览器会删除一些回调，从不执行即可。只有 setTimeout 才能保证执行。

Don't use setInterval, as in some cases (lots of setInterval + long callbacks, which are usually longer than timeout), due to limited queue size, some callbacks will be dropped by the browser and never executed. Only setTimeout guarantees execution.
