JS setTimeout()替代

Question

就像我在这里解释的那样,我不能再使用window.setTimeout()和任何窗口经典函数,如clearInterval等...); 但我需要调用JS块代码作为异步.

这就是我使用XHR请求的原因.

使用XHR实现window.setTimeout()的智能替代方法的最佳方法是什么？

// Not working :(
setTimeout(function(){ 
  document.getElementById("messageTimer").innerHTML = "Happy New Year ! (old version)";
}, 10);

// with or without jQuery - but XHR
jQuery.ajax({
    url: "/local/url/easy",
    success: function(html, textStatus, jqXHR) {
            // a loop ?
            // timeout done ?
            document.getElementById("messageTimer").innerHTML = "Happy New Year ! (working version)"
 }});

尝试使用jQuery 版本 3.0 .animate()，它现在使用requestAnimationFrame

  // Creates a jQ object where elem set to index of [0]
  // a plain object with value of 0 `{to:0}`
  // call .animate() chained to the jQ object
  // Animates `{to:0}` value from 0 - 1
  // $({to:0}).animate({to:1}

var duration = 5000;
$({to:0}).animate({to:1}, duration, function() {
  // do stuff after `duration` elapsed
  $("#messageTimer").html("Happy New Year ! (working version)")
})

<div id="messageTimer"></div>
