I want to display the alert box but for a certain interval. Is it possible in JavaScript?
This question is related to
javascript
tooltips can be used as alerts. These can be timed to appear and disappear.
CSS can be used to create tooltips and menus. More info on this can be found in 'Javascript for Dummies'. Sorry about the label of this book... Not infuring anything.
Reading other peoples answers here, I realized the answer to my own thoughts/questions. SetTimeOut could be applied to tooltips. Javascript could trigger them.
In short, the answer is no. Once you show an alert, confirm, or prompt the script no longer has control until the user returns control by clicking one of the buttons.
To do what you want, you will want to use DOM elements like a div and show, then hide it after a specified time. If you need to be modal (takes over the page, allowing no further action) you will have to do additional work.
You could of course use one of the many "dialog" libraries out there. One that comes to mind right away is the jQuery UI Dialog widget
I finished my time alert with a unwanted effect.... Browsers add stuff to windows. My script is an aptated one and I will show after the following text.
I found a CSS script for popups, which doesn't have unwanted browser stuff. This was written by Prakash:- https://codepen.io/imprakash/pen/GgNMXO. This script I will show after the following text.
This CSS script above looks professional and is alot more tidy. This button could be a clickable company logo image. By suppressing this button/image from running a function, this means you can run this function from inside javascript or call it with CSS, without it being run by clicking it.
This popup alert stays inside the window that popped it up. So if you are a multi-tasker you won't have trouble knowing what alert goes with what window.
The statements above are valid ones.... (Please allow). How these are achieved will be down to experimentation, as my knowledge of CSS is limited at the moment, but I learn fast.
CSS menus/DHTML use mouseover(valid statement).
I have a CSS menu script of my own which is adapted from 'Javascript for dummies' that pops up a menu alert. This works, but text size is limited. This hides under the top window banner. This could be set to be timed alert. This isn't great, but I will show this after the following text.
The Prakash script above I feel could be the answer if you can adapt it.
Scripts that follow:- My adapted timed window alert, Prakash's CSS popup script, my timed menu alert.

If you are looking for an alert that dissapears after an interval you could try the jQuery UI Dialog widget.
May be it's too late but the following code works fine
document.getElementById('alrt').innerHTML='<b>Please wait, Your download will start soon!!!</b>';
setTimeout(function() {document.getElementById('alrt').innerHTML='';},5000);
<div id='alrt' style="fontWeight = 'bold'"></div>
setTimeout( function ( ) { alert( "moo" ); }, 10000 ); //displays msg in 10 seconds
