jQuery Validation Plugin

The jQuery Validation Plugin can help webmasters prevent erroneous form submissions by checking the data on the client side before sending it to the server.

The plugin provides developers with a preset list of checks which they can apply on their forms before taking the data and sending it to a desired remote server location for further processing.

These checks and validation procedures can be filtered and only the ones that fit the form's field types can be used.

The plugin's core also features an extensible codebase which can easily be improved with new checks and procedures.

If errors are detected they are shown inline with the respective form field, without pesky alert windows.

The jQuery Validation Plugin comes with a lots of examples to show developers how it can be used.
