我相信有一百万种方法可以做得更好，但我想我可以通过创建一个对象来尝试一下：

// execute code consecutively with delays (blocking/non-blocking internally)
function timed_functions()
{
    this.myfuncs = [];
    this.myfuncs_delays = []; // mirrors keys of myfuncs -- values stored are custom delays, or -1 for use default
    this.myfuncs_count = 0; // increment by 1 whenever we add a function
    this.myfuncs_prev    = -1; // previous index in array
    this.myfuncs_cur    = 0; // current index in array
    this.myfuncs_next  = 0; // next index in array
    this.delay_cur     = 0; // current delay in ms
    this.delay_default = 0; // default delay in ms
    this.loop = false;      // will this object continue to execute when at end of myfuncs array?
    this.finished = false;  // are we there yet?
    this.blocking = true;   // wait till code completes before firing timer?
    this.destroy = false;   // <advanced> destroy self when finished


    this.next_cycle = function() {
        var that  = this;
        var mytimer = this.delay_default;

        if(this.myfuncs_cur > -1)
            if(this.myfuncs_delays[this.myfuncs_cur] > -1)
                mytimer = this.myfuncs_delays[this.myfuncs_cur];

        console.log("fnc:" + this.myfuncs_cur);
        console.log("timer:" + mytimer);
        console.log("custom delay:" + this.myfuncs_delays[this.myfuncs_cur]);
        setTimeout(function() {
        // Time is up! Next cycle...
        that.cycle();

    }, mytimer);
}

this.cycle = function() {

    // Now check how far we are along our queue.. is this the last function?
    if(this.myfuncs_next + 1 > this.myfuncs_count)
    {
        if(this.loop)
        {
            console.log('looping..');
            this.myfuncs_next = 0;
        }
        else
            this.finished = true;
    }

    // First check if object isn't finished
    if(this.finished)
        return false;

    // HANDLE NON BLOCKING //
    if(this.blocking != true) // Blocking disabled
    {
        console.log("NOT BLOCKING");
        this.next_cycle();
    }

    // Set prev = current, and current to next, and next to new next
    this.myfuncs_prev = this.myfuncs_cur;
    this.myfuncs_cur  = this.myfuncs_next;
    this.myfuncs_next++;

    // Execute current slot
    this.myfuncs[this.myfuncs_cur]();

    // HANDLE BLOCKING
    if(this.blocking == true)  // Blocking enabled
    {
        console.log("BLOCKING");
        this.next_cycle();
    }

    return true;
};

// Adders
this.add = {
    that:this,

    fnc: function(aFunction) {
        // Add to the function array
        var cur_key = this.that.myfuncs_count++;
        this.that.myfuncs[cur_key] = aFunction;
        // Add to the delay reference array
        this.that.myfuncs_delays[cur_key] = -1;
    }
}; // end::this.add

// setters
this.set = {
    that:this,

    delay: function(ms) {
        var cur_key = this.that.myfuncs_count - 1;
        // This will handle the custom delay array this.that.myfunc_delays
        // Add a custom delay to your function container

        console.log("setting custom delay. key: "+ cur_key + " msecs: " + ms);
        if(cur_key > -1)
        {
            this.that.myfuncs_delays[cur_key] = ms;
        }
        // So now we create an entry on the delay variable
    },

    delay_cur:      function(ms) { this.that.delay_cur = ms; },
    delay_default:  function(ms) { this.that.delay_default = ms; },
    loop_on:        function()   { this.that.loop = true; },
    loop_off:       function()   { this.that.loop = false; },
    blocking_on:    function()   { this.that.blocking = true; },
    blocking_off:   function()   { this.that.blocking = false; },

    finished:            function(aBool) { this.that.finished = true; }
}; // end::this.set


// Setters
this.get = {
    that:this,

    delay_default: function() { return this.that.delay_default; },
    delay_cur:     function() { return this.that.delay_cur; }
    }; // end::this.get

} // end:::function timed_functions()

使用方式如下：

// // // BEGIN :: TEST // // //

// Initialize
var fncTimer = new timed_functions;

// Set some defaults
fncTimer.set.delay_default(1000);
fncTimer.set.blocking_on();
// fncTimer.set.loop_on();
// fncTimer.set.loop_off();


// BEGIN :: ADD FUNCTIONS (they will fire off in order)
fncTimer.add.fnc(function() {
    console.log('plan a (2 secs)');
});
fncTimer.set.delay(2000); // Set a custom delay for previously added function

fncTimer.add.fnc(function() {
    console.log('hello world (delay 3 seconds)');
});
fncTimer.set.delay(3000);

fncTimer.add.fnc(function() {
    console.log('wait 4 seconds...');
});
fncTimer.set.delay(4000);

fncTimer.add.fnc(function() {
    console.log('wait 2 seconds');
});
fncTimer.set.delay(2000);

fncTimer.add.fnc(function() {
    console.log('finished.');
});
// END :: ADD FUNCTIONS


// NOW RUN
fncTimer.cycle(); // Begin execution


// // // END :: TEST // // //

我建议以前的python开发人员使用此方法

const sleep = (time) => {
   return new Promise((resolve) => setTimeout(resolve, Math.ceil(time * 1000)));
};

用法：

await sleep(10) // for 10 seconds

首先，应该使用setTimeout和setInterval，因为JavaScript具有回调性质。如果您想使用sleep（），则是控制流或代码架构不正确。

尽管如此，我想我仍然可以帮助实现两个睡眠。

1.我头顶上的假同步跑步：

// A module to do that //dual-license: MIT or WTF [you can use it anyhow and leave my nickname in a comment if you want to]
var _ = (function(){
  var queue = [];
  var play = function(){
    var go = queue.shift();
      if(go) {
        if(go.a) {
          go.f();
          play();
        }
        else
        {
          setTimeout(play, go.t);
        }
      }
  }
  return {
    go:function(f){
      queue.push({a:1, f:f});
    },
    sleep:function(t){
      queue.push({a:0, t:t});
    },
    playback:play
  }
})();

[也可以自动播放]

// Usage

_.go(function(){

  // Your code
  console.log('first');

});

_.sleep(5000);

_.go(function(){

  // Your code
  console.log('next');

});

// This triggers the simulation
_.playback();

2.实际同步运行

有一天，我对它进行了很多思考，我在JavaScript中真正睡觉的唯一想法就是技术。

睡眠函数必须是同步Ajax调用，超时设置为睡眠值。这就是真正睡觉的唯一方法。

我会将setTimeOut封装在Promise中，以实现与其他异步任务的代码一致性：Fiddle中的Demo

function sleep(ms)
{
    return(new Promise(function(resolve, reject) {
        setTimeout(function() { resolve(); }, ms);
    }));
}

它的用法如下：

sleep(2000).then(function() {
   // Do something
});

如果您习惯使用Promise，那么很容易记住语法。

如果（像我一样）你在Rhino中使用JavaScript，你可以使用。。。

try
{
  java.lang.Thread.sleep(timeInMilliseconds);
}
catch (e)
{
  /*
   * This will happen if the sleep is woken up - you might want to check
   * if enough time has passed and sleep again if not - depending on how
   * important the sleep time is to you.
   */
}

需要使用“休眠”方法的对象的方法，如下所示：

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function () {
    this.DoSomething1(arg1);
    sleep(500);
    this.DoSomething2(arg1);
}

几乎可以翻译为：

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function (arg1) {
    var self = this;
    self.DoSomething1(arg1);
    setTimeout(function () {
        self.DoSomething2(arg1);
    }, 500);
}

不同之处在于，“SomeMethod”操作在执行操作“DoSomething2”之前返回。“SomeMethod”的调用者不能依赖于此。由于“睡眠”方法不存在，我使用后一种方法并相应地设计代码。
