In this article, we will see how to convert a string into a number in AngularJS, along with understanding its implementation through the illustrations.
Approach:
Example 1: In the first example, the string ’90’ is converted to an integer.
HTML
<!DOCTYPE HTML>
<html>
<head>
<script src=
</script>
<script>
var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.a = '90';
$scope.isNumberA = angular.isNumber($scope.a);
$scope.convertToInt = function () {
$scope.a = parseInt($scope.a);
$scope.isNumberA = angular.isNumber($scope.a);
};
});
</script>
</head>
<body style="text-align:center;">
<h1 style="color:green;">

var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.a = "10";
$scope.b = "20";
$scope.strToInt = function () {
$scope.a = parseInt($scope.a);
$scope.b = parseInt($scope.b);
};
