Help with piece of code
I want the following piece of code to check if a user has submitted a valid number for tickets. It displays the alert if value=0 or "" but it still continues onto the next page. How does continue to the next page till the user inputs a valid number for tickets.
function VerifyForm() {
var strFormName = document.frmselect;
if ( document.frmselect.tickets.value == 0 || document.frmselect.tickets.value =="")
{
alert("Either you have not requested any tickets, or have entered a 0.");
exit();
}
else {
strFormName.submit();
return true;
}
}

I assume you are calling your function using the onSubmit event handler of the form?
If so then if you use onSubmit="return VerifyForm();" and you return false from VerifyForm instead of exit (What does exit do anyway?)If you aren't living life on the edge
- you're taking up too much space
