angular-form-validation

Description

This advanced module for AngularJS provides you with facilities to automate form validation,
error display and input decorations. No more manual application of ngClass directives
to all the form elements and creating error messages for every possible input.
Just install this module and provide input requirements the standard way by using native HTML5
attributes like maxlength, required and standard AngularJS directives like ngMin, ngMax
and the like. No need to add directives to all the input fields.

You can configure this module to decorate forms as you see fit only once and all the forms of
your application will automatically benefit from it.

$3

- Works out of the box with almost zero configuration
- No need to specify any additional directives besides standard input constraints
- Has built-in supports for Bootstrap 3, see the Using Bootstrap 3 section
- Automatically decorates valid, invalid and non-modified input fields
- Automatically adds error messages to invalid input fields
- Supports translations (i18n) and provides some [built-in languages][built-in-languages]
- Designed with flexibility in mind, almost every aspect of this module
can be configured and overridden (see [the API section][docs-api] of this document)
- You can easily select DOM elements to decorate by providing custom traversing functions
- You can change the way forms are decorated by overriding some aspects of existing decorators or
by providing your own implementation of them
- You can change the way error list is rendered by modifying default error list renderer or
by providing your own implementation
- jQuery is not required since version 1.0.3

Feel free to play with the Demo.

Installation

$3

This library requires [angular-input-modified][github-input-modified] module.
It is used to detect modified input fields.

$3

bower install --save angular-form-validation

$3

`` html

`

Use minified version: angular-form-validation.min.js in production
and uncompressed version: angular-form-validation.js during development/testing.

Also, don't forget to add dependencies, see Dependencies section above.

$3

` javascript
var application = angular.module('application', [
// ...
'ngFormValidation'
]);
`

Usage

This module is working out of the box with default settings and no configuration.
However, in order to unleash it's full potential, you should provide additional
configurations through exposed providers. Please see [the API documentation][docs-api] in order
to understand how to do this. It's written for real humans!

$3

In order for this module to work, you must have semantically correct HTML form, i.e.
all your input elements must be placed inside of a form element.

Also, all your form and input elements must have a name attributes with unique values.

$3

This module provides Bootstrap 3 support out of the box.

Just add the following code to your project:

`JavaScript
module

// ...

.config([
'formValidationDecorationsProvider',
'formValidationErrorsProvider',
function(
formValidationDecorationsProvider,
formValidationErrorsProvider
) {
formValidationDecorationsProvider
.useBuiltInDecorator('bootstrap')
;
formValidationErrorsProvider
.useBuiltInErrorListRenderer('bootstrap')
;
}
])

// ...

;
`

And if you want to use fontawesome icon library instead of glyphicons (default):

`JavaScript
formValidationDecorationsProvider
.useBuiltInDecorator('bootstrap')
.useIconLibrary('fontawesome')
;
`

API

See the detailed [API documentation][docs-api].

Forced validation

Since version 1.0.1 of this module, input elements are not decorated in any way if they are pristine.
To counter this behavior functionality called "forced validation" was introduced.

- Call ngModel.forceValidation(true/false) to enable/disable forced validation for this input element
- Call ngForm.forceValidation(true/false) to set forced validation on all form elements

When forced validation is enabled for an input element it will be decorated even if it's pristine.

---

If you want to force validation on form as soon as controller is loaded, you should use the following trick:

`javascript

.controller('DefaultController', function($scope, $timeout) {
// ...
$timeout(function () {
$scope.form.forceValidation(true);
}, 0);
})

`

Using $timeout with zero interval makes sure, that our code is executed when
compilation is complete and $scope.form` is available.
