Masked Input Plugin is a masked input plugin for the jQuery javascript library. It allows a user to more easily enter fixed width input where you would like them to enter the data in a certain format (dates,phone numbers, etc).

A mask is defined by a format made up of mask and placeholder characters. Any character not in the placeholder character list below is considered a mask character. Mask characters will be automatically entered for the user as they type and will not be able to be removed by the user. The following placeholder characters are predefined:

* a - Represents an alpha character (A-Z,a-z)
* 9 - Represents a numeric character (0-9)
* * - Represents an alphanumeric character (A-Z,a-z,0-9)

It has been tested on Internet Explorer 6/7, Firefox 1.5/2, Safari, and Opera. The file size is very small with only 7.3k and 2.8k for the Packed version.

Creating accessible Web2.0 applications can be a tricky process. Many of the advanced widgets and controls we develop today don’t exist in the current HTML specification — there is no “slider” element. So Filament Group has developed an accessible slider based on the core principle of progressive enhancement with jQuery.

Filament Group designed and developed an accessible slider with a very nice interface which allows users to choose one or a range of values on a continuum. Values on a slider can represent anything from hours on a clock to the volume on a music player to a complex, proprietary data set. In its simplest form, the slider is displayed as an axis of values with a handle to drag and select a value, or two handles for selecting a range.

The code is open source and licensed under GPL. You can view source to grab the code from this working example.

Password Strength Checker is an application that is designed to assess the strength of password strings. The instantaneous visual feedback provides the user a means to improve the strength of their passwords, with a hard focus on breaking the typical bad habits of faulty password formulation. Since no official weighting system exists, Password Strength Checker has created its own formulas to assess the overall strength of a given password.

Password Strength Check is written in Javascript and released under GPL License. You are allowed to download this application and integrate it into your web application. I am sure it will help users choosing a more secure password when filling in registration forms. However, this application is neither perfect nor foolproof, and should only be utilized as a loose guide in determining methods for improving the password creation process.

Flexible WYSIWYG editing in the browser is still an inconsistent affair at best in terms of user experience, integration effort, and generated markup. In the meantime a crop of text formatting languages such as Markdown, Textile, BBCode and wiki markup have emerged as ways for users to enter rich content in a controlled enviornment.

Control.TextArea provides a toolbar for textareas where users are entering text in one of these markup languages. In addition to a toolbar it provides access to a cross browser text selection and manipulation API so that creating new functionality, or integration with your custom application features is vastly easier. The design of Control.TextArea is very clean and clear. It requires Prototype.js to work.

Would you like to include an input that resembles the famous Apple Mail to: textfield? It would be something similar to Facebook List Input. Basically, it’s a group of pieces or bits, that can be either a box or an input. The user is able to move around between the bits by using his keyboard or his mouse. You can remove the bits by click the “x” symbol.

It has a auto complete feature as well. It works by caching all the results from a JSON Request and feeding them to the autocompleter object. When a item is added as a box, it’ removed from the feed array, and when the box is disposed it’s added back, so that it becomes available in the list when the user types. You’ll also be able to let it add boxes from the HTML directly. If you are interested in this amazing textboxlist, you can view the full article.

Nowadays everybody knows that javascript can be used to validate input data in HTML forms before sending off the content to a server. Despite of that, when there are many fields in the form, the JavaScript validation becomes too complex and boring to code. That’s why fValidator exists, with it form validations are many times easier. fValidator is compatible and tested in Internet Explorer, Firefox (and its mozilla friends), Opera and Safari.

*** It works perfect with iMask as it’s complement.

Requirements: Any Modern Browsers
