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 :

Show alert
Hide/terminate alert within 2 seconds

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);

You can't close an alert box with Javascript.

You could, however, use a window instead:

var w = window.open('','','width=100,height=100')
w.document.write('Message')
w.focus()
setTimeout(function() {w.close();}, 5000)

Answer 3

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl:

You can also try Notification API. Here's an example:

function message(msg){
    if (window.webkitNotifications) {
        if (window.webkitNotifications.checkPermission() == 0) {
        notification = window.webkitNotifications.createNotification(
          'picture.png', 'Title', msg);
                    notification.onshow = function() { // when message shows up
                        setTimeout(function() {
                            notification.close();
                        }, 1000); // close message after one second...
                    };
        notification.show();
      } else {
        window.webkitNotifications.requestPermission(); // ask for permissions
      }
    }
    else {
        alert(msg);// fallback for people who does not have notification API; show alert box instead
    }
    }

To use this, simply write:

message("hello");

Instead of:

alert("hello");

Note: Keep in mind that it's only currently supported in Chrome, Safari, Firefox and some mobile web browsers (jan. 2014)
