  Form Field Validation  Archive Import (Jeff Krause) at 08:58 on Wednesday, May 22, 2002
 

I am trying to implement a field validation function:

function validate()
{
var result = true;
var x=document.problem_form.explanation.value;
if ((x==null) || (x.length==0))
{
alert("Please enter an explanation");
result = false;
}
return result;
}


Now if the field is empty, it will display the alert window, but it will also perform the FORM ACTION. I can't figure out why. Is there some special situation that will make it perform the ACTION that I just happen to be in? Any advice would be great.

Thanks,
Jeff Krause

Hi Jeff
You probably need to call the function using return eg.

onsubmit="javascript:return validate()"

that should then pick up the false I think.

Hope that helps
David
