JS File:
[code]function generate()
{
window.alert(‘Oh, hai. Script and **** be working.’);
}
function checkValid()
{
var errors = new Array(‘Please fill in all fields.’,’Both entries must be ONLY numbers.’,’Please use only WHOLE numbers.’);
var err_flag = false;
var form = document.numbers;
if(form.num1 == null || form.num1 == ” || form.num2 == null || form.num2 == ”)
{
err_flag = true;
window.alert(errors[0]);
return false;
}
}
I really cannot find anything wrong with it. What I’m trying to do is check if the fields are empty and then stopping the script if they are; however, it doesn’t! Chome user here.
Please help… I’m a really decent webguy, but I was just reminded why I stick to the server side.
