Bypassing form validation

[Duran Harris]

Hi,

I have a form that has validation on the textfields.The validation methods run with the submit's onclick event...
But now I have noticed that if a user presses enter,the form will be submitted without any validation being performed...
What can I do about this??

The validation should be run in an "onSubmit" handler of the form itself. Then it gets called no matter how the form is submitted.

You probably know this, but make sure to repeat any validations on the server. You can't rely on JavaScript code being run on the client.

Okay here is the problem:

<script>
function validate()
{
      if(textfieldsMeetRequirements)
      {
       document.forms[0].submit;
      }

else
return false;

}
<script>
<form action="something.php" method="POST" onsubmit="validate()"/>
      //Textfields
     //Textfields
     //Textfields
    <input type="submit" value="submit" onclick="validate()"/>
</form>

This works fine when the user clicks submit BUT if the user presses enter:
-the validate function will run and return false but the data is already posted!!

Also we can rely on javascript alone because the system is used by call-centre operators in the company
ie.they all have javascript enabled in their browsers

You need to write " onsubmit="return validate()" " in order for the return value to be used for stopping the form submission.
