“True website professionals recognize that time is of the essence in website functions."
ProFormPlus uses JavaScript validation as the first method of checking for correct form field completion. We use JavaScript client-side validation because it is fast. This is because it is a programming language that is enabled on a user's own computer.
We display the error messages at the field, not on a second page or a pop-up. This makes form completion a lot more efficient. Not only that, ProFormPlus has instant error message removal the moment the data is corrected (a JavaScript function).
JavaScript is great, but one of the best parts about ProFormPlus is it works the same without JavaScript enabled. This is an important point because many security experts consider client-side validation unstable - it can be turned off on the user's computer.
JavaScript can be disabled on the user's own computer, which means one of two things:
1. If the function is written in JavaScript (client-side) programming alone, it will not work at all if JavaScript is off.
 This is BAD because many site visitors won't be able to use the form.
2. If the form is MADE in server-side programming language, but only VALIDATED in JavaScript, it has no form validation whatsoever.
This is VERY BAD because it leaves your website vulnerable to the insertion of
malicious code.
