AngularJS(17)-Angular小程序

现在可以开始创建您的第一个 AngularJS 应用程序，一个 AngularJS 单页 Web 应用。

<!DOCTYPE html>
<html lang="en" ng-app="myNoteApp">
<head>
    <meta charset="UTF-8">
    <title>笔记</title>
    <script src="angular-1.4.1/angular.min.js"></script>
    <script src="myNoteApp.js"></script>
    <script src="myNoteCtrl.js"></script>
</head>
<body>
   <div ng-controller="myNoteCtrl">
       <h2>我的笔记</h2>
       <p><textarea ng-model="message" cols="40" rows="10"></textarea></p>
       <p>
           <button ng-click="save()">保存</button>
           <button ng-click="clear()">清除</button>
       </p>
       <p>剩余字数:<span ng-bind="left()"></span></p>
   </div>
</body>
</html>

myNoteApp.js:

var app = angular.module('myNoteApp',[]);

myNoteCtrl.js:

app.controller('myNoteCtrl', function ($scope) {
   $scope.message = "";
    $scope.left = function () {
      return 100-$scope.message.length;
    };
    $scope.clear = function(){
        $scope.message = "";
    };
    $scope.save = function () {
       alert('保存成功!');
    };
});

　　运行结果：
