JavaScript：一次同时多次发布到页面

Question

我尝试在同一时间循环几次将POST发送到站点。 但是现在发生的是，它等待直到第一个完成，然后为下一个allsounds进行POST，然后创建Delay。

代码：

var allsounds = ["sound.wav","adom.wav","alarm.wav","tiny.wav","calm.wav","tiny4.wav","tiny5.wav","tiny4.wav",""];

  for (var i = 0; i < allsounds.length; i++) {
      $.post("alerts.php", {zone: zone, list: allsounds[i]});

      $.post("alerts1.php", {zone: zone, list: allsounds[i]});

      $.post("alerts2.php", {zone: zone, list: allsounds[i]});

}
