Forms

This series of functions provide common form validation for required fields, dates, numbers, and email addresses.

Checking that form fields have input is extremely important - having this performed before the form is submitted, client side, before its handled by anything at the backend such as an SQL or MS Access database, is vital and an additional factor in getting accurate input. This code contains functions to check null input and also to check if an email address follows a valid pattern.

JavaScript-based HTML checker that allows you to check your code without saving it somewhere else.

A cool JavaScript/DHTML and cookies driven address book.

This program illustrates how to actually read and process fields of information from a form (including proper number to number conversion) on a webpage WITHOUT the need of having to actually use the traditional submit button (and writing sometimes long parsing functions that everyone seems to be using) before any processing is done.

Does your form contain an "Accept terms" section users must agree to before submitting the form? If so, this script helps enforce it, by disabling the submit button (in IE4+ and NS6+) or process (all other browsers) until he/she checks a box indicating compliance.

This script "auto tabs" a form field (and jumps to another field) once the length of the field's value has exceeded a certain length. It works in conjunction with the "maxlength" attribute of HTML, triggered whenever the user's input reaches the maxlength's value.

Many forms will require the user to enter an email address twice (to check for typographical errors). This script immediately notifies the user when the two fields match - it's a nice, user-friendly touch, and safe for all browsers.

100% Client Side JavaScript Sortable Grid Control. This control supports form elements within the grid and is capable of sorting on form element changes. Works in NS 6.2 and above and IE 5.0 and above. Easy to customize for your web site.

Check Form is a form validation script that checks if all fields in the form have been filled out. The script can be easily extended.

This script limits the amount of text a user can enter into particular INPUT or TEXTAREA elements, plus displays in real time the number of characters remaining.

Originally written for a website design company that required users to firstly input a domain name choice and then to choose their primary e-mail address, this little script 'echoes' or duplicates the domain name value, copying itself to the end of the E-mail address, which then cannot be changed.

This script validates the date that the user inputs for the following sample format: 23 Feb 1983

Increase the "intuitiveness" of filling out forms on your site with this script. It applies coloring to the form element in focus, better indicating which one the user is currently on.

This is a JavaScript Form validator. When you submit the form, it validates the data you entered in the various fields. You are allowed to enter only alphabetical characters in the "Name" field.
