Form E-Mail Validation Help..

[sal007]

Hi people,

Just struggling a little with some scripting..

I've got this form with 3 fields(Name, Email, Idea) and i've currently got some javascript validating it, to make sure that each field has text entered within it.


<script language="JavaScript" type="text/javascript" >
function validate_form ( )

{



valid = true;
if ( document.comp.name.value == "" )
{
alert ( "please provide your name!" );
valid = false;
}
else
if ( document.comp.email.value == "" )
{
alert ( "please provide your email address!" );
valid = false;
}
else
if ( document.comp.idea.value == "" )
{
alert ( "please provide an idea for our student accommodation site" );
valid = false;
}
return valid;





}
</script>


I call this in my form, and it works fine..


<form name="comp" action="sendmail.php" method="post" onsubmit="return validate_form ( );" >


However, I wish to add some extra validation to the "email" field. I've seen plenty of email validation scripts around, but i'm not sure how to incorporate it, as it will be two different functions altogether. I guess I sound like a noob, i'm just not very skilled up when it comes to javascript!

Any help appreciated!

Cheers,

Sal

Cheers for that matey, if i'm right that's the OR operator in an IF statement? I have tried this, but maybe i've been botching it up somewhere..

I'd be really grateful if you could show me how to incorporate the IF statement with OR, with the E-Mail validation script provided by Dynamic Drive.

Cheers for that mate, unfortunately it didn't work though. I think a "}" was missed to close the 1st IF statement for the email condition. However, I corrected that, but it doesn't work.

All the fields are blank, and when I press the button, the popup appears "please provide your name" and the form just submits.

Any additional help really appreciated!

Regards,
