Changing button text (toggle text) on click in AngularJS

We can make a button behave like a toggling button by making a directive in AngularJS. It is very simple. You just need to bind the attribute and then check the condition.

First create a simple HTML :-

<html>

  <head>

      <link rel="stylesheet" type="text/css" href="css/index.css">

      <link rel="stylesheet" type="text/css" href="css/myApp.css">

      <title>Hello World</title>

  </head>

Promises in Angular.JS

By using Promises we can execute a function asynchronously. we can use promises to specify what to do when a operation is success or failed. We have $q built in keyword in angular js for promises. let's create a example :

.service('drawHomeCardService', function(apiCallFactory, $q) {

  this.getTheLogo = function() {

      var deferred = $q.defer();

      apiCallFactory.getData().success(function(response) {

          var logo         = response[2].businessInfo.logoFilePath;

          var logoFilePath = 'https://oyokeydev.s3.amazonaws.com/' + logo;

          deferred.resolve(logoFilePath);

      }).error(function(response) {

          console.log('Something went wrong');

          deferred.reject('Something went wrong');
