angular-autodisable - ngAutodisable directive for angular. Automatic disable for buttons rocks!

May 18, 2017

An extension to angular ng-click directive that automatically sets the element to disabled if the handler would return a promise.

Requirements


  1. angular.js version >1.2+
  2. following es6 functions:

Usage


Include ngAutodisable as dependency
 angular.module('MyApp', [ 'ngAutodisable', ... ]);  
If that's done then just follow those simple steps:
  • just attach ng-autodisable directive to the element which happens to have ng-click directive OR a form that has the ng-submit directive.

On an element

 <button ng-click="doSomething()" ng-autodisable>Do something</button>  
  <a ng-click="doSomething()" ng-autodisable>Do something</a>  

On a form

 <form ng-submit="doSomething()" ng-autodisable>   
   ...  
   <button type="submit">Submit</button>   
  </form>  
The button with type submit within the form will be disabled.

Loading class


You can optionally add a list of classes which will be added to the element while this is disabled. This is useful to add a spinner or something similar.
 <button ng-click="doSomething()"   
      ng-autodisable-class="class1 class2"   
      ng-autodisable>  
   Do something  
  </button>  
  <form ng-submit="doSomething()"   
     ng-autodisable-class="class1 class2"  
     ng-autodisable>   
   ...  
   <button type="submit">Submit</button>   
  </form>  
The button with type submit within the form will get the class.

Demo


A quick demo is available at jsfiddle

How it works


When ngClick and ngAutodisable are on the same element then ngAutodisable overwrites the handler for click event. The default ngClick action is recreated (and passes all the angular specs).

If the click handlers result happens to be a promise ($http or $q) then the element attribute disabled will be set as true. If the promise fulfills then the element disabled attribute will be removed. This also works with multiple click handlers, given that click handlers are separated by ; as such:
 <button ng-click="doSomething();doSomethingElse()" ng-autodisable>Do something</button>  
If there are multiple click handlers then the element disabled style will be removed after the last promise resolves.

Note


Throws an exception ngAutodisable requires ngClick attribute in order to work if ngAutodisable is on an element without ngClick.
