The confirm( ) Method
This method is used to obtain confirmation from the user about an action. For example, if a user wants to delete
something or cancel a purchase on an online website, a dialog box will display asking the user to acknowledge the
deletion or order cancellation.
Ð ÐConfirm method brings up a dialog box with a question mark icon, a question, and two buttons: OK and Cancel.
Ð ÐIt gives the value of the clicked button.
Ð ÐIt only needs one argument, which is the question to ask the user.
ÐIf the user clicks the OK button, a true value is returned.
Ð
Ð ÐIf the user presses the Cancel button, the returned value is set to false.
Example:
<HTML>
<HEAD>
<TITLE> Using confirm box </TITLE> </HEAD>
<BODY>
<script type="text/javascript">
var answer=confirm("Do you want to cancel your Aadhaar Application?");
