validation 3
Get flash to fully experience Pearltrees
For today’s programming tutorial, I’m going to show how to pass input arrays through an AJAX request using JQuery . This tutorial will assume that you have at least basic knowledge of using JQuery, and also have knowledge of any scripting language of choice (Perl, PHP, Python, Ruby, etc). For those who have been using JQuery, its been quite frustrating to know that the usual method for passing multi-valued parameters like checkboxes is by giving each checkbox a unique name or id. Sure its a little hassle at first when processing your backend if you only have a few selections needed, but what about larger forms with 20 or more inputs?
JQuery Tutorial: Passing Input Arrays
Remember my tutorial on implementing input arrays in jQuery ? It seems that there is much simpler way of doing it without too much hassle coding the individual parameters, and remebering all the field #id’s. That is if you don’t mind loading another 29KB JavaScript library. Introducing the Form Plug-in for JQuery, this library will be of great help for very large forms that needs to be processed via AJAX For this tutorial, we will use the same form as the one before.
jQuery Form: Input Arrays Made Easier
This series of posts on using jQuery with no prior knowledge comes to its fifth iteration. Today, I'm going to look more in depth at the Validation Plug-in. We'll be looking at what rules the Validation Plug-in comes with out of the box followed by an example of how to create your own rules. In addition to the typical project that I typically supply, I am also including a list of custom Validations that I have used to hopefully make everyone's life a little easier. If you would like to review the previous posts in this series, please feel free to review the links below:

JavaScript Form Validation | Front-End Book
This article is an introduction on how to approach and create efficient form validation with javascript. I will briefly describe the interaction pattern of client side validation with javascript. Later I will focus on 10 actions/tips/mindsets that will make your form validation perfect. Table of Contents The Design Pattern of Client Side Form Validation Use a Form validation library or framework Focus on solving the biggest problems Validate form before the form is submitted Use API-based validation for business data input Do extensive testing of client side validation Rewrite input data to valid formats Attach form validation late in the design process Make the validation i18n- and l10n-compatible Add events and callbacks to your validation library Make your library extensible External Resources The Design Pattern of Client Side Form Validation
There’s two types of validation: Simple, server-independent validation, i.e. checking email address are the right format, password and confirm password matches, etc. Server-based validation, with can be delivered with a page refresh, or live (as this tutorial will explain), i.e. for checking whether a username is taken. What can we do?
Using Ajax to Validate Forms | jQuery for Designers - Tutorials
One struggle that still remains today in web design is displaying all of the redundant information on every page. For example, a login form. What if there was a way to easily make the content accessible on every page, but keep it hidden until needed? Well you can, by making a top panel that when clicked, will reveal its self and its content. But we need to make this look nice, so we'll also animate it. In this tutorial, we'll create a sliding panel, that slides in to reveal more content, using JQuery to animate the height of the panel.

webforms2 - Google Code
Update, 7 November 2010: Moving to GitHub: https://github.com/westonruter/webforms2 Update, 3 June 2009: Now that the Web Forms 2.0 has been edited into HTML5, this project will seek to implement as much of the HTML5 Forms section as possible. This will be a complete rewrite of the codebase.File inputs ( <input type="file" /> ) are the bane of beautiful form design . No rendering engine provides the granular control over their presentation designers desire. This simple, three-part progressive enhancement provides the markup, CSS, and JavaScript to address the long-standing irritation. Before we get down to the nitty gritty details, check out the demo or, if you’re a Mint user, check out your settings page in the Mint Account Center (requires login). The Markup <label class="cabinet"><input type="file" class="file" /></label>

The following code controls the HTML form beneath it. It uses ajaxForm to bind the form and demonstrates how to use pre- and post-submit callbacks. AJAX response will replace this content.

File upload forms that don't suck
Most file upload forms suck. It's not just the lack of design, but also the unintuitive and inflexible interface. There is usually a single file upload field, where you need to select and upload files one at a time.Design interactive error handling for Web apps
One of usability guru Jakob Nielsen's top ten usability heuristics is "Error Prevention: Even better than a good error message is a careful design which prevents a problem from occurring in the first place." Sure, in Nielsen's perfect world of blue and purple links, I can agree with that. But in the real world, errors happen and they must be dealt with. By understanding the context in which errors frequently occur, developers can best design an application's resulting error interactions and visual feedback to help the user resolve the errors.Flex Quick Start Basics: Validating Data
Adobe Products Top destinations Education Adobe Creative Cloud Design and photographyHere you will see LiveValidation in action, and the code that makes it all happen, to serve as examples of its capabilities and as tutorials to get you started. IMPORTANT - As you probably already know, relying on client-side validation alone is a very bad idea. Always perform appropriate server-side validation as well. The purpose of this library, and javascript validation in general, is not to replace server-side validation, but make the act of filling in a form less daunting for a user, and to save them time.
