Javascript变量间隔

Question

我需要电传一条消息，但我想要字母之间的随机间隔。这是我的固定间隔代码:

$( document ).ready(function()
{
  var message = 'Is it possible to create a random interval in javascript?';
  var intervalId = window.setInterval( function ()
  {
    if(message.length>0) 
    {
      setTimeout(function () 
      {
        $("#message_area").append(message[0]);
        message = message.substring(1);
      }, 0);
    }
  }, 150);
});

您可以为每一轮使用setTimeout 并设置下一个计时器。 https://jsfiddle.net/baz7gjed/

$( document ).ready(function()
{

  function writeWord(){
    if(message.length>0){
      $("#message_area").append(message[0]);
        message = message.substring(1);
        window.setTimeout( writeWord, Math.random()*500); //edit your random boundary here
      }
    }

  var message = 'Is it possible to create a random interval in javascript?';
  window.setTimeout( writeWord, 150);
});
