formValidator

formValidator works by analyzing a field's content as soon as the user moves to the next field.

If the entered data is not compliant to the field's type or validation rules, an error is shown.

Data is processed and analyzed in real-time using jQuery, and the errors can be shown in various ways.

The plugin can be used with normal forms or with ones submitted via AJAX.

formValidator also comes very well documented, with lots of ready-made validation rules, and with a few demos.

Custom rules can also be added, just in case the default package does not cover what developers have expected.
