在JavaScript中睡眠 - 在动作之间延迟 [英] Sleep in JavaScript - delay between actions

问题描述

在执行其他操作之前，有没有办法让我在JavaScript中睡觉？

Is there a way I can do a sleep in JavaScript before it carries out another action?

示例：

 var a = 1+3;
 // Sleep 3 seconds before the next action here
 var b = a + 4;

推荐答案

您可以使用 setTimeout 实现类似的效果：

You can use setTimeout to achieve a similar effect:

var a = 1 + 3;
var b;
setTimeout(function() {
    b = a + 4;
}, (3 * 1000));

这不是'睡眠'JavaScript - 它只是执行传递给<$ c $的函数c> setTimeout 经过一段时间（以毫秒为单位）。尽管可以为JavaScript编写睡眠函数，但最好使用 setTimeout ，因为它不会在睡眠期间冻结所有内容。

This doesn't really 'sleep' JavaScript—it just executes the function passed to setTimeout after a certain duration (specified in milliseconds). Although it is possible to write a sleep function for JavaScript, it's best to use setTimeout if possible as it doesn't freeze everything during the sleep period.
