Smart Forms

Smart Forms has more than 20 validation types and extra features that make using forms a better experience. The best practice of form validation involves two stages: 1) JavaScript validation since it is fast and it takes the load off the server; 2) Server-side validation since it does not depend on user’s software and therefore it can not be bypassed. Smart Forms includes PHP script that performs exactly the same validation as JavaScript, so you can easily implement this scheme. Validation is based on data types (number, word, alphanumeric, date, e-mail, etc) and comparisons (including numeric, text length, and selected items count comparisons). Also, you can add extra features to the form, including character counters for textarea & input tags (this way, when you set length limitation you can let the user know how many character he/she has left), groups of fixed size fields such as year-month-day (when you enter 4-digit year the focus automatically shifts to the month field), etc.

Form Element Virtual Keyboard Interface

Add accessibility to your text field, password field and textarea form elements with this handy javascript virtual keyboard. Simply include the javascript and CSS files in your pages, and apply a special class to the elements you want to be "keyboard enabled". An icon will appear beside all enabled form elements which, when clicked, will make a virtual keyboard appear *within* the page - NOT a popup window. Users can then type characters into your forms using the mouse only. Add your own keyboard layouts to make choosing the appropriate special characters a snap! Comes with US, UK, Norwegian and Dvorak keyboard layouts pre-configured. Users can switch between available keyboard layouts without reloading pages. Useful for letting users type special characters on computers which have unfamiliar keyboard layouts, or to allow text input from computers where keyboard input is impossible or has been disabled.

JS Auto Form Validator

This is a very easy-to-setup form validation script. The main idea is: we heed to write NOTHING of JavaScript to handle whole form validation process. This script allows you to specify certain form elements as "required" or "non-required" and also what specific type they have: text, password, numeric, zip code etc. The script checks automaticly all required elements to make sure that they are NOT only empty before allowing the form submission, but also that the surfer entered a valid type value.

Formchecker

Anyone that has ever developed a web-application will probably have been confronted with the frustrations of it's users, that if they leave the page without saving the data they have entered, it all will be lost.This script will end those frustrations!! When included in any page (with the script-tag) you can activate it once the page is loaded (with the onLoad event) to store the current 'states' of all the forms in the web-page. Then, when the user tries to leave the page, it will perform another check and if it appears the state of the form(s) have been altered (the user has changed some data), it will alert the user of this and give the possibility to cancel leaving the page It also provides a function with which you can submit any form without triggering this alert. And it also provides a possibility to exclude certain elements from the check (so they can be changed without triggering the warning)

nioColorfind

nioColorfind uses a super smooth interface to allow your users to pick HEX colors quickly and easily. It utilizes a overlay Javascript layer which is displayed when the users presses the "pick color" button next to the form and it is almost guaranteed to work perfectly on your site. Unlike some Javascript colorpickers nioColorfind allows access to way more than 1,000,000 colors quickly and without straining your webserver bandwidth. nioColorfind released as 1.0 BETA and any problems or bugs that are reported will be fixed relatively quickly. It is developed by the professional web designers from nioDesign.com. It is coded and tested to work in IE6+, Firefox 1.5+ and Opera 9+. Support for Safari and Konqueror are planned - please report any problems you experience in these browsers.

Prevent Multiple Form Submit

There are many times when users are impatient and submit forms twice or even three times. Here is some javascript that will prevent the user from submitting more than once.

Javascript Get or Set Checked Radio Value

This pair of Javascript function can get or set the checked value of a group of radio buttons. These functions are specially designed for dynamic pages, and work without error with zero, one, or more radio buttons. Also, because the radio length is saved before looping, this function is much faster. Finally, the functions are granted to the public domain.
