清除所有setIntervals [英] Clear all setIntervals

问题描述

我正在像这样的each()函数中使用setIntervals

I'm using setIntervals within an each() function like so

$(".elements").each(function() {
    setInterval(function() {

    }, 1000);
});

显然，为每个元素创建了一个setIntervals.

Obviously a setIntervals is created for each element.

我的问题是:当我不再需要所有setIntervals时，该如何清除它们?我试过将setInterval存储在变量中并调用window.clearInterval(int)，但这仅清除了最后一个setInterval，因为每个变量都被覆盖.

My question is: How do I clear all the setIntervals when I no longer need them? I have tried storing the setInterval in a variable and call window.clearInterval(int), but that only clears the last setInterval since each variable is overridden.

推荐答案

设置时间间隔后，您将获得一个指向它的指针:

When you set an interval, you get a pointer to it:

var myInterval = setInterval(function(){}, 4000);

如果要取消间隔，请执行以下操作:

If you want to cancel an interval, you do the following:

clearInterval(myInterval); 

因此，对于您想做的事情，您将执行以下操作:

So, for what you want to do, you would do the following:

var intervals = [];
$(".elements").each(function() {
    var i = setInterval(function() {

    }, 1000);
    intervals.push(i);
});

然后，如果您需要取消它们，则可以执行以下操作:

Then if you need to cancel them all you can do this:

intervals.forEach(clearInterval);

那应该为您做.
