The onsubmit event is an event that occurs when you try to submit a form. You can put your form validation against this event type. The following example shows how to use onsubmit. Here we are calling a validate() function before submitting a form data to the web server. If validate() function returns true, the form will be submitted, otherwise, it'll not submit the data.

<html>
   <head>
      <script>
         <!--
            function validation() {
               all validation goes here
               .........
               return either true or false
            }
         //-->
      </script>
   </head>
   <body>
      <form method = "POST" action = "t.cgi" onsubmit = "return validate()">
         .......
         <input type = "submit" value = "Submit" />
