        </div>
        </body>
  </html>

please help me to solve this.....

I don't undertand what

ss[i].checked in function checkname(ss) is supposed to do?
ss.checked in function checkemail(ss) is supposed to do?

can you please help me to find a code for validation of fields in text box???

ie i have a form in which there is two textfields for entering name and email.. when i click ' submit' it is gone to my email..

when anyone clicks 'submit' whenever a field is blank , it should display an alert message..

hope you understood .......

Thanks......

Establish a submit handler on the form in which you can validate the fields. Return false in order to prevent the form from submitting is you find problems.

There is already a submit handler in the code - onsubmit="return validate();" which does return false (agree its in bad shape) when the validation fails. Or does a submit handler mean something else?

Yes certainly they are not related to textbox property.
