The confirm dialog box is used to confirm a user's answer to a question. A question mark will appear in the box with an OK button and a Cancel button. If the user presses the OK button, true is returned; if he presses the Cancel button, false is returned.

<script language="JavaScript" type="text/javascript">
        if (confirm("Are you sure you want to do this?") == true) {
            alert("You have clicked OK !!!");
