如果使用ES6，你可以使用for循环来实现:

For(令I = 1;I < 10;我+ +){ setTimeout(函数定时器(){ console.log(“hello world”); }， I * 3000); ｝

它为每次迭代声明i，这意味着超时是+ 1000之前的超时。这样，传递给setTimeout的就是我们想要的。

在我看来，在循环中添加延迟的最简单和最优雅的方法是这样的:

names = ['John', 'Ana', 'Mary'];

names.forEach((name, i) => {
 setTimeout(() => {
  console.log(name);
 }, i * 1000);  // one sec interval
});

我用蓝鸟的承诺。延时和递归。

函数 myLoop（i） { 返回承诺延迟（1000） .then（function（） { 如果 （i > 0） { 警报（“你好”）; 返回 myLoop（i -= 1）; } }); } 我的循环（3）; <script src=“//cdnjs.cloudflare.com/ajax/libs/bluebird/2.9.4/bluebird.min.js”></script>

Hey, I know this post is very old, but this code "loops" and adds a delay to it using a recursive method. I don't think you can 'actually' delay a loop itself from iterating based on reading various comments from other people. Maybe this can help someone out! Basically the function accepts an array (in this example). On each iteration the setTimeout Javascript method is called. The function calls itself again indefinitely when the timer of the setTimeout function expires, but on each call the array becomes smaller until it reaches the base-case. I hope this can help anyone else out.

你这样做:

console.log(“嗨”) Let start = 1 setTimeout(函数(){ let interval = setInterval(函数(){ if(start == 10) clearInterval(interval) 开始+ + console.log(“你好”) }, 3000) }, 3000) < script src = " https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js " > < /脚本>
