如何在函数运行后等待一段时间 [英] How to wait for a period of time after a function run

问题描述

如果我有一个函数，我希望我的js代码立即运行，但运行后，等待2秒。如何实现这个逻辑？

If I have a function which I would like my js code to run it immediately but after the run, wait for 2 seconds. How to achieve this logic?

（注意：这只是与 setTimeout（）的逆逻辑比较，因为 setTimeout（）首先等待一段时间然后执行该函数。）

(Note: It is just the inverse logic compare with setTimeout(), since setTimeout() first wait a certain amount of time then execute the function.)

推荐答案

只需将您的代码放入传递给setTimeout的匿名函数中。

Just put your code inside an anonymous function passed to setTimeout.

例如

functionToRunFirst();
setTimeout(function() {
    // rest of code here
}, 2000);
