Complexify is a jQuery plugin for accurately telling users how secure is their password.

The developer puts the motivation behind this plugin very succinctly:

If your password is 8 characters long and only formed of lower case characters, you need to make it better, perhaps by adding a number or more characters.

If your password is 25 characters long but happens to not contain a number, you shouldn’t be forced by a password security policy to add one, you clearly have a very secure password.

The minimum criteria for a password’s complexity are quite satisfactory: a minimum-security password should take at least 600 years to crack on a commodity machine.

ALAJAX is a jQuery plugin for turning your forms AJAX with a few lines of code.

ALAJAX works even with dynamic (JS-powered) forms, replacing default functionality and turning regular requests into AJAX requests, then translating them for the server.

The plugin is lightweight, meticulously documented, and easy to modify if that’s your thing.

minjs is a compilation of JS UI widgets with numerous uses.

There are three modules — minform, longtable, and drcal — which can be included independently.

minjs could be called a collection of frameworks, as the three modules are ready for customization, and leave styling up to you.

longtable automatically converts an HTML table to a pretty, paged table; minform holds several important attributes like ‘placeholder’, ‘required’, and ‘autofocus’; but drcal offers easy ways of date calculation and a few other date-related tasks.

Juice UI is a collection of WebForms that brings jQuery’s UI widgets to ASP.NET.

Juice allows creating flexible and interactive web apps with no fuss, by introducing additional functionality through jQuery’s widgets.

This seems like a ‘port’ that should have been rather anticipated, so its less-than-one-would-expect 59 watchers on GitHub can spark some thought at least.

Formalize is a neat set of libraries for making forms consistent over different web browsers.

Formalize is compatible with a number of popular libraries, and requires either Dojo, jQuery, MooTools, Prototype, or YUI to operate.

Forms can be a pain in the ass processor, and Formalize offers a great solution that gives you control over the appearance of forms in different browsers.

mailcheck.js is a nice and compact jQuery library for spell-checking email domain names in input elements.

mailcheck.js supports a virtually unlimited amount of domain names — they are passed to the plugin in an array–, and this makes the library especially useful for local projects.

The markup is rather simple, and the plugin adds much-needed extra security to sign-up forms.
