Confirmation Box in JavaSript Example

Updated on August 13, 2015     Kisan Patel

If we want to confirm an action from user, we need to use javascript confirm() method.

The javascript confirm() method displays a confirm dialog box with a message with an OK and Cancel button.

The confirm method() returns true if the user clicked “OK”, otherwise return false.

<!-- HTML -->
<input type="button" onclick="ConfirmMe()" value="Click me to confirm!" />

<!-- Javascript -->
<script type="text/javascript">
function ConfirmMe() {
   var c = confirm('Are you sure to proceed?');
   if (c) {
     // OK pressed; user confirmed to proceed further
     alert("You pressed OK!");
   }
   else {
     // Cancel pressed; user do not want to proceed
     alert("You pressed Cancel!");
   }
}
</script>
