如何在javascript中获取所有计时器? [英] How can I get all timers in javascript?

问题描述

我在不同的类中使用 setTimeout() 函数创建了不同的计时器.我想知道是否有办法将所有超时放在一起?

I create different timer with setTimeout() function in different class. I want to know if there is a way to get all timeouts together?

推荐答案

默认情况下没有，没有.您可以制作自己的模块，让您跟踪计时器，并为您提供列表.大致:

Not by default, no. You could make your own module that lets you keep track of the timers, and which gives you the list. Roughly:

// ES2015+ version
const activeTimers = [];
exports.setTimeout = (callback, interval, ...timerArgs) => {
    const handle = setTimeout((...args) => {
        const index = activeTimers.indexOf(handle);
        if (index >= 0) {
            activeTimers.splice(index, 1);
        }
        callback(...args);
    }, interval, ...timerArgs);
    activeTimers.push(handle);
};
exports.getActiveTimers = () => {
    return activeTimers.slice();
};

...然后使用它的 setTimeout 而不是全局的.

...then use its setTimeout instead of the global one.
