Angular Input Modified

angular-input-modified

Bower

This Angular.js 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 with 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 an entire form or just a single field to it's initial state (cancel all user edits) with just a single call to the reset() method or lock new values (preserve new state) just by calling overloaded $setPristine() method.

Demos and examples

Please see the demos hosted on our GitHub Pages or open them locally.

Also, feel free to play with our Plunk!

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 end user will see what elements were actually changed.

This module also supports animations if ngAnimate module is available.

Installation

Install library with bower

bower install --save angular-input-modified

Add library to your page

<script src="/bower_components/angular-input-modified/dist/angular-input-modified.js"></script>

You should use minified version (angular-input-modified.min.js) in production.

Add dependency in your application's module definition

var application = angular.module('application', [
  // ...
  'ngInputModified'
]);

Usage

Please see our demos and examples as well as API documentation.

Form initialization

Starting from version 2.0.0 form must be synchronously initialized during controller execution. If you need some data to be fetched prior to form initialization — the best approach is to resolve this data using your router.

However, if you really need to re-initialize form after controller execution — please use the approach shown in this demo: Delayed Initialization.

Excluding some fields

Input modified module provides you with the ability to control which input elements will exhibit modifiable behavior and which will not.

By default all form fields in your application will support modifiable behavior, after input modified module is added to the application. You can control this via enableGlobally() and disableGlobally() methods of the inputModifiedConfigProvider. This gives you the overall top-level switch to control modifiable behavior.

Also, we provide you with special directive called bsModifiable that allows you to control which fields will support the behavior. It gives you are more granular control over your forms. This directive works in a recursive manner and can be applied to any HTML element. For example, you can apply it to an entire form: <form name="myForm" bs-modifiable="true"> in order to enable modifiable behavior on all it's fields.

bs-modifiable attribute can be set to true or to false, depending on what you are trying to achieve.

You can exercise the exclusion policy by excluding only specific fields or you can exercise the inclusion policy by disabling the behavior globally and then adding modifiable behavior only to the required forms or form fields. It's all up to you!

Please see the special demo.

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')
    ;
  })
;
Method Description
enableGlobally() Enables modifiable behavior globally for all form elements (this is default)
disableGlobally() Disables modifiable behavior globally for all form elements
setModifiedClassName({string} className) Provides CSS class name that will be added to modified elements. ng-modified is the default one
setNotModifiedClassName({string} className) Provides CSS class name that will be added to unmodified elements. ng-not-modified is the default one

ngModel

Property Type Description
masterValue mixed Initial value of the form field
modified boolean Flag that indicates whether the form field was modified
Method Description
reset() Resets input value to it's initial state
$setPristine() Makes form field pristine by preserving current value as a new master value

ngForm

Property Type Description
modified boolean Flag that indicates whether the form is modified
modifiedCount integer The number of modified form fields
modifiedModels array The list of modified model controllers
modifiedChildFormsCount integer The number of modified child forms
modifiedChildForms array The list of modified child form controllers
Method Description
reset() Resets all input fields of the form to their initial states
$setPristine() Makes form pristine by making all child forms and form fields pristine

bsModifiable

This directive can be applied to any element on the page. All descendant form fields (recursively) will respect it.

Attribute Type Description
bs-modifiable string Either "true" or "false", see "excluding some fields" chapter

FAQ

How do I access demos locally?

Node.js must be installed in your OS.

  • Install Gulp by running npm install -g gulp
  • clone the repo
  • run gulp demo in the repo's root directory
  • open http://localhost:8888/

Developer guide

Fork, clone, create a feature branch, commit, create a PR.

Run:

  • npm install && bower install to initialize the project
  • gulp build to re-build the dist files
  • gulp demo to run local webserver with demos
  • gulp demo-deploy to deploy GitHub Pages

Do not add dist files to the PR itself. We will re-compile the module manually each time before releasing.
