Form validation using jQuery Poppa Plugin

In this article, we will learn how to implement form validation using jQuery Poppa plugin. It is a very easy to use, reliable, cross-browser friendly, and lightweight plugin that makes client-side validation very simple.

Output:

Before Validation:

After Validation:

Enter some invalid input to check the validation done by the plugin.
 

Example 2: The following example demonstrates the above example with active live validation with some minor custom changes. When live validation is enabled, it allows each input to be validated immediately. This happens when the user types into the input or when it loses focus.
