To enable or disable button on checkbox selection we need to use ng-disabled property in AngularJS we need to write the code like as shown below.
<!DOCTYPE html>
<html ng-app>
<head>
<script src="http://code.angularjs.org/1.2.0/angular.min.js"></script>
</head>
<body> Check Me: <input type="checkbox" ng-model="checked"><br/> <button ng-model="button" ng-disabled="checked">Button</button> </body>
</html>
