angular-input-modified

This AngularJS module adds additional properties and methods to the ngModel and ngForm controllers as well as CSS classes to the underlying form elements to provide end-user with facilities to detect and indicate changes in form data.

This extra functionality allows you to provide better usability for forms. For example, you can add decorations to the form elements that are actually changed. That way, user will see what values has changed since last edit.

Also, you can reset form to it's initial state (cancel all user edits) with just a single call to form.reset() or lock new values (preserve new state) just by calling augmented form.$setPristine() method. If you want, you can do this for individual input elements the same way.

Demos and examples

Please see /demos directory or visit our GitHub Pages.

Decorations and animation

This module adds ng-modified and ng-not-modified CSS classes (names are customizable) to the input fields to indicate their state. Use them in your CSS to decorate input fields. You can combine multiple classes in the same selector. For example, use this convenient CSS selector to decorate modified elements as valid:

/** Decorating only modified inputs as valid */
input.ng-valid.ng-modified {
    border-color: green;
}

This way target user will see what elements were actually changed.

This module also supports animations if ngAnimate module is available.

API

inputModifiedConfigProvider

Use this provider to configure behavior of this module. Every setter of this provider supports methods chaining. See example:

angular.module('Application', ['ngInputModified'])
    .config(function(inputModifiedConfigProvider) {
        inputModifiedConfigProvider
            .disableGlobally()
            .setModifiedClassName('my-changed')
            .setNotModifiedClassName('my-clear')
        ;
    })
;

enableGlobally

{ConfigProvider} enableGlobally()

Enables modifiable behavior globally for all form elements (this is default).

disableGlobally

{ConfigProvider} disableGlobally()

Disables modifiable behavior globally for all form elements. You will have to add this behavior manually by using bsModifiable directive

setModifiedClassName

{ConfigProvider} setModifiedClassName({string} className)

Provides CSS class name that will be added to modified elements. ng-modified is the default one.

setNotModifiedClassName

{ConfigProvider} setNotModifiedClassName({string} className)

Provides CSS class name that will be added to unmodified elements. ng-not-modified is the default one.
