How can I auto hide alert box after it showing it? [duplicate]

Question

All I want to do is, how can I auto hide alert box within specific seconds after showing it?

All I know is,

setTimeout(function() {        alert('close');  }, 5000);  // This will appear alert after 5 seconds 

No need for this I want to disappear alert after showing it within seconds.

Needed scenario :

1. Show alert

2. Hide/terminate alert within 2 seconds

tldr; jsFiddle Demo

This functionality is not possible with an alert. However, you could use a div

function tempAlert(msg,duration) {  var el = document.createElement("div");  el.setAttribute("style","position:absolute;top:40%;left:20%;background-color:white;");  el.innerHTML = msg;  setTimeout(function(){   el.parentNode.removeChild(el);  },duration);  document.body.appendChild(el); } 

Use this like this:

tempAlert("close",5000);
