下面这个示例在输入框键入回车键或者点击按钮时，将输入框的值置为"Hello World!"：（黄色背景内容为响应回车事件涉及到的代码）
<html ng-app="myApp"> <head> <meta charset="utf-8"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"> <title>angularjs-demo</title> <script type="text/javascript" src="lib/angularjs/angular.min.js" charset="utf-8"></script> </head> <body ng-controller="ctrl"> <input type="text" ng-model="text1" ng-keyup="enterEvent($event)" /> <button ng-click="clickEvent()">test</button> </body> <script type="text/javascript"> var app = angular.module(‘myApp‘, []) .controller(‘ctrl‘, function($scope){ $scope.clickEvent = function() { $scope.text1 = "Hello world!"; } $scope.enterEvent = function(e) { var keycode = window.event?e.keyCode:e.which; if(keycode==13){ $scope.clickEvent(); } } }); </script> </html>
