人气:0

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>
