jquery form validation

Here you could find some jquery plugins that could help you validate some forms.

• jQuery Validation.

A single line of jQuery to select the form and apply the validation plugin. And a bit of metadata on each element to specify the validation rules.

Of course that isn’t the only way to specify rules. You also don’t have to rely on those default messages, but they come in handy when starting to setup validation for a form.

• Auto Help.

Sometimes it’s important to tell the user what’s expected of him. Especially when filling out a complicated form. This plugin uses the title attribute to display help in a separate DOM element.

• Simple jQuery form validation.

The form goes nowhere, but shows some form input validators both serverside and browserside.

Incorrect values range from 0-6 characters and 12+ characters. Additional validations can easily be added

The server returns a JSON object which the script eval’s

• jQuery XAV – form validations.

jQuery.yav is a new plugin for to integrate YAV form validation wih jQuery, making the form validation more easy, accessible, usable and W3C standard. Now you can validate forms with a more easy form, and if you like, you can get all the power of the custom and extended setting of this plugin, setting more complex validations. jQuery.YAV add also, a little bug repair for YAV library for multiple values in class attribute and not requires yav-config.js file. Tested in IE 6 and 7, Firefox 2, Netscape 7, Safari 4 for Windows, Konqueror 3.5 in Linux and Opera 9 but must work in jQuery compatible browsers.

• jQuery AlphaNumeric.

jQuery AlphaNumeric is a javascript control plugin that allows you to limit what characters a user can enter on textboxes or textareas. Have fun.

• Masked Input.

This is a masked input plugin for the jQuery javascript library. It allows a user to more easily enter fixed width input where you would like them to enter the data in a certain format (dates,phone numbers, etc). It has been tested on Internet Explorer 6/7, Firefox 1.5/2/3, Safari, Opera, and Chrome.   A mask is defined by a format made up of mask literals and mask definitions.

• TypeWatch Plugin.

Earlier this week I created a jQuery plug-in that allows you to potentially determine when a user has finished typing in a textbox. I created it for a search textbox on one of my websites so that I could return results by firing some AJAX after they’re done typing. It could help with an AJAX auto-complete implementation too.

• Text limiter for form fields.

Counts down the number of chars left on a Textarea/Input fields,
won’t let the user write more than allowed number of characters.
When copy/paste text, it trims it to the set limit, and also
has an option for slow trimming, char by char (define speed).

• Ajax Username Check with jQuery.

The embedded javascript picks up the onblur event of the input field with id username.

It then sends a post request to check.php which checks the csv for the filename and returns the result.

The embedded javascript then updates the span element with id usernameResult.
