A jQuery plugin that understands HTML5 forms and knows how to validate them based on new input attributes such as "required" and "pattern", even in browsers that don't yet support HTML5.

In browsers that do support HTML5, h5Validate allows you to respond to validation failure, so that you can display helpful error messages to your users.

There are a ton of options you can override by passing key: value pairs when you call .h5Validate():

This plugin allows you to make a form element disabled if specified condition is not satisfy, and enable it as soon as it is.
Currently available conditions are :

• checked
• empty
• disabled
• hasCssClass
• lt (lower than)
• lte (lower than or equal)
• longer (stricly longer)
• shorter (strictly shorter)
• length

All conditions can be negated using ! operator.
Limitations :

• Conditions can only apply to one element. For example, it is not possible to compare two fields values.
• You can only refer to an element by its ID (I know, this is stupid !)

This plugin does not perform any validation of any kind.

Further development will allow user to select an element for condition using jQuery selectors, to check conditions on more than one element, apply a custom style, hide rather than disable, execute a custom callback, ...

Sample uses :

The goal of this plugin is to allow you to count the number of lines in a textarea and get some general statistics about the lines. Mainly, this plugin allows you to detect wrapped lines. Currently, the plugin can generate these statistics for any textarea:

• The number of lines in the textarea.
• The number of lines in the textarea that wrap at least once.
• The total number of times all lines wrap.
• The approximate number of lines that the user actually sees in the textarea.
• The number of blank lines.

The plugin works for textareas of any size (although it is most accurate for the high end of small and medium to large textareas). It adjusts automatically depending on what font, font size, and other font-related attributes are being used.

This plugin has been tested under Firefox 3.6.9 using jQuery 1.4.2.

Formation is a jQuery plugin that allows you to quickly create a form with validation without writing any HTML. You simply specify the container you wish to append the form to. By passing a few parameters into one of the formation function calls you can add different validation such as number, e-mail, url, phone number, or zip code. Each element that you create can be fully customized. You can set the class, id, or any other attribute that is native to that element. Enjoy!
