Do you ever receive multiple copies of a single form submission? Do your visitors click the submit button over and over, hoping it will hurry up the process? This script will solve the problem by preventing the visitor from submitting the form after the first submission. Basic field validation also included

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.

This is a simple JavaScript example for allowing users to select/highlight a textarea content with a click of button.

This is a Web-based wizard that generates a JavaScript form validation code with textfields and a text area. Type the text that will appear next to each textfield, the textfield names, and choose the textfields width and max number of characters. You can also choose which textfields are required, required email, reqiured number, etc. Type in the button label (Enter, Submit, etc.) Then click the "create form" button to generate the code. Use it or add it to your site for free.

jsVal is a JavaScript program used for validating HTML Forms on the client side. This allows HTML forms to be validated in the browser without having to send a request to a sever (PHP, ASP, Perl...). jsVals saves you from having to write complicated validations on server side as well as helping you avoid having to rebuild and repopulate the form when validation fails.

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.

This function allows you to read form variables from static HTML. Combined with the document.write() method, you can actually add dynamic content to regular HTML. Given a choice, server side processing of form variables is preferable.

Client side java script is the efficient way to validate the user input in web forms. It gives the response immediately and reduces the server load. But, when there are many forms in the project and when the forms are long, writing the form validations becomes a daunting, repetitive task. Save yourself from coding long validations for your forms. Here is a simple, powerful form validation code. Using this code, you can do the common form validations in a snap.

Automatically repopulates the state drop down based on the country selected with no page refreshes. Eliminates the need of refreshing or re-posting a page to display a new list of states or provinces when a new country is selected. When a new country is selected the state/province drop down is repopulated with the state/provinces for that country. If there are no states or provinces, a text box is displayed.

Foul is a JavaScript based, form validation language released under GPL so it's free to use and modify as long as the license stays intact. If you're familiar with the huge Netscape FormChek.js file which is sometimes used on forms, then you already know what Foul does. Foul contains a full language parsing engine which compiles advanced conditions and tests for the fields of a form. My goal is to have this script completely mirror the range of tests that FormChek.js does but in a much easier, cleaner and quicker way.
