JSP page yes/no dialog box

Question

I have three fields on JSP Update page userid, name and ssn.. I would like to have simple dialog box saying "You already have ssn, are you sure you want to modify it?" depending on the user's yes or no response than it performs the task? Is there a way I can add something on my java code to make this happen.. any help would be great.. thank you..

Answer 1

You should use java script for this.

<script type="text/javascript">
    var response = confirm ("You already have ssn, are you sure you want to modify it?")
    if (response){
      //do yes task
    }else{
     //do no task
    }
</script>
