据我所知，setTimeout函数是异步调用的。你能做的是将整个循环包装在一个异步函数中，并等待一个包含setTimeout的Promise，如下所示:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

然后像这样调用运行它:

looper().then(function(){
  console.log("DONE!")
});

请花些时间好好理解异步编程。

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。

你可以使用RxJS的间隔操作符。Interval每x秒发出一个整数，take指定它发出这些数字的次数。

Rx。可观测的 .interval (1000) (10), .subscribe((x) => console.log(x)) < script src = " https://cdnjs.cloudflare.com/ajax/libs/rxjs/4.1.0/rx.lite.min.js " > < /脚本>

我认为你需要这样的东西:

var TimedQueue = function(defaultDelay){
    this.queue = [];
    this.index = 0;
    this.defaultDelay = defaultDelay || 3000;
};

TimedQueue.prototype = {
    add: function(fn, delay){
        this.queue.push({
            fn: fn,
            delay: delay
        });
    },
    run: function(index){
        (index || index === 0) && (this.index = index);
        this.next();
    },
    next: function(){
        var self = this
        , i = this.index++
        , at = this.queue[i]
        , next = this.queue[this.index]
        if(!at) return;
        at.fn();
        next && setTimeout(function(){
            self.next();
        }, next.delay||this.defaultDelay);
    },
    reset: function(){
        this.index = 0;
    }
}

测试代码:

var now = +new Date();

var x = new TimedQueue(2000);

x.add(function(){
    console.log('hey');
    console.log(+new Date() - now);
});
x.add(function(){
    console.log('ho');
    console.log(+new Date() - now);
}, 3000);
x.add(function(){
    console.log('bye');
    console.log(+new Date() - now);
});

x.run();

注意:使用警报暂停javascript执行，直到你关闭警报。 它的代码可能比您要求的要多，但这是一个健壮的可重用解决方案。

这个脚本适用于大多数情况

function timer(start) {
    setTimeout(function () { //The timer
        alert('hello');
    }, start*3000); //needs the "start*" or else all the timers will run at 3000ms
}

for(var start = 1; start < 10; start++) {
    timer(start);
}
