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 called the Currency Filter. This “currency” filter includes the “$” Dollar Symbol as default. So, we can use the following code for the HTML template format of Currency Filter.

{{ currency_expression | currency : symbol : fractionSize}}

Code 

HTML

The following HTML code contains the root directory “ng-app” and 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 we 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;
});

Removing Default Symbol of Currency Filter

HTML

In the following code value = “ ” , so the default Symbol “$” Dollar will be removed.

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

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

</div>
