Currency Filter In AngularJS

Introduction

 

In this article you will learn about Currency Filter in AngularJS.

 

 

AngularJs :

AngularJS is a JavaScript framework. It was originally developed by Hevery and Adam Abrons. Now it’s maintained by Google. AngularJS is lightweight and easy to learn. It is perfect in Single Page Application projects. AngularJS is open source, free of cost, and easy to handle. 

 

Currency Filter

 

One of the filters in AngularJS is the Currency Filter. This “currency” filter includes the “$” Dollar Symbol as the default. So we can use the following code as the html template format of Currency Filter. 

{{ currency_expression | currency : symbol : fractionSize}}

Code

 

Html :

 

The following html code contains the root directory “ng-app” & Controller “ng-controller”. So you can create any name for it. The AngularJS currency filter contains the “$” Dollar symbol as default. 

<div ng-app="CurrencyApp" ng-controller="CurrencyController">
   <input type="number" ng-model="amount">
   <h2>{{ amount | currency }}</h2>
</div>

AngularJS

 

When we run the following code you will get the result as “$1000”. So you can change this “$” Dollar symbol based on the html template format of Currency Filter.

var myApp = angular.module('CurrencyApp', []);
myApp.controller('CurrencyController', function($scope) {
  $scope.amount = 1000;
});

<div ng-app="CurrencyApp" ng-controller="CurrencyController">

   <input type="number" ng-model="amount">
   <h2>{{ amount | currency : value="" }}</h2>
   <!-- or-->
   <h2>{{ amount | currency : "" }}</h2>
