*Chilled Buttons for AngularJS*



For Angular 2+ version [go here](https://github.com/johannesjo/angular2-promise-buttons).



There are cool loading buttons out there for angular. Only thing which annoys me, is that you (most of the times) have to manually trigger their loading state via a boolean which leads to a bit of repetition, declaring those again and again. ```angular-promise-buttons``` exists to take away some of that, by handling the loading state directly by passing the promise. Saves you at least two lines of code every time. Check out the [DEMO](http://johannesjo.github.io/angular-promise-buttons/#demo)!



Also you can play with the code on [Plnkr](http://plnkr.co/edit/yKrlohXVL15fRjTjZHBJ?p=preview).



[Bug-reports or feature request](https://github.com/johannesjo/angular-promise-buttons/issues) as well as any other kind of **feedback is highly welcome!**



## getting started



Install it via bower or npm

```

bower install angular-promise-buttons -S

# or via npm

npm install angular-promise-buttons -S

```

and add `angularPromiseButtons` as dependency in your main module:

```

angular.module('yourApp',[

  'angularPromiseButtons'

]);

```



Using the buttons is easy. Just return the promise in question in your service caller and you're good to go:

You can also directly return the promise via the function passed to `ng-click`:

```html

Click me to spin!

```



```javascript

// inside some controller

$scope.yourServiceCaller = function ()

{

  return fakeFactory.method().then(...);

};

```

### using it for forms

For using the promise buttons with `ng-submit` you need to apply them to the form directive and add `type="submit" to the buttons you want to show a loader for:

```html



  MyBtn



```



```javascript

// inside some controller

$scope.yourServiceCaller = function ()

{

  return fakeFactory.method().then(...);

};

```



### alternative syntax and using $event

There is also an alternative syntax, which allows you to share promises between buttons (and possibly other directives) and is especially useful, if you want to use the `$event` somehow:

```html

MyBtn

```

Now you just have to assign a promise to ```yourPromise```:

```javascript

// inside some controller

$scope.yourServiceCaller = function ()

{

  $scope.yourPromise = fakeFactory.method().then(...);

  // this is now also possible

  $event.preventDefault();

};

```



## styling the button

The base-styles might not be overwhelmingly sexy, but it is easy to fix that! There are lots of free css-spinners out there. Just find one of your liking and add the css.

## configuration

There are also some defaults for you to set, if you like. You can do this by using the ```angularPromiseButtonsProvider```:

```javascript

angular.module('exampleApp', [

  'angularPromiseButtons'

])

.config(function (angularPromiseButtonsProvider)

{

  angularPromiseButtonsProvider.extendConfig({

    spinnerTpl: '',

    disableBtn: true,

    btnLoadingClass: 'is-loading',

    addClassToCurrentBtnOnly: false,

    disableCurrentBtnOnly: false,

    minDuration: false,

    CLICK_EVENT: 'click',

    CLICK_ATTR: 'ngClick',

    SUBMIT_EVENT: 'submit',

    SUBMIT_ATTR: 'ngSubmit',

    BTN_SELECTOR: 'button'

  });

});

```



## change options via `promise-btn-options`

You can also change all the options (**but not the spinner template**) by specifying the options via `promise-btn-options`:

```html

MyBtn Look I'm nested content



```

Now you just have to assign a promise to ```yourPromise```:

```javascript

// inside some controller

$scope.options = {

  disableBtn: false,

  btnLoadingClass: 'is-spinning'

};

$scope.yourServiceCaller = function ()

{

  $scope.yourPromise = fakeFactory.method().then(...);

};

```



Thats all the logic there is (for now). Adjusting the look and feel of the spinner can be done using your own styles.



## ❤ contribute ❤

I'm happy for any [issue or feature request](https://github.com/johannesjo/angular-promise-buttons/issues), you might encounter or want to have. Even a one liner is better, than no feedback at all. Pull requests are also highly welcome. Just fork the repository, clone it and run `grunt serve` for development. Another important factor is the number of developers using and thus testing `angular-promise-buttons`. Tell your fellow programmers, [say that you use it on ng-modules](http://ngmodules.org/modules/angular-promise-buttons), tweet or even blog about it.
