In this article, we will see how to set checkboxes checked with the click of a button in AngularJS.
Approach: The approach is to use the ng-checked directive to check the checkbox in the DOM. In the first example, a single checkbox is checked by the button and In the second example, multiple checkboxes are checked by the button. The ng-model directive is used to bind the checkboxes.
Example 1: This example describes the implementation of the ng-checked directive to check the checkbox in AngularJS.

</script>
<script>
var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.checkIt = function () {

$scope.check = true;
} else {
