angularjs中响应回车事件

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>
