Validate a simple form using JQuery
Apr 23rd
This is a way to validate a form using simple JQuery. Why re-invent the wheel when there’s so many type of wheels to choose from? and also, for sometimes, we are just lazy to find the best wheel possible for our project. What I’m trying to do here is not to spoon feed you the code, but to provide a simple and straight forward guide to very simple validation. I love simplicity
Let’s get straight to business! View it in action here.
