    MVC模式的清单列表效果


    使用WebStorm新建todo.html并链入bootstrap.css、bootstrap-theme.css、angular.js。要链入的相关css和js文件预先准备好,文件目录如下: 
    文件目录

    使用MVC模式前的代码:

    <!DOCTYPE html>
    <html ng-app>
    <head>
        <meta charset="UTF-8">
        <title>TO DO List</title>
        <link href="./bootstrap/css/bootstrap.css" rel="stylesheet"/>
        <link href="./bootstrap/css/bootstrap-theme.css" rel="stylesheet"/>
    </head>
    <body>
        <div class="page-header">
            <h1>Yimi's TO DO List</h1>
        </div>
        <div class="panel">
            <div class="input-group">
                <input class="form-control"/>
                <span class="input-group-btn">
                    <button class="btn btn-default">Add</button>
                </span>
            </div>
            <table class="table table-striped">
                <thead>
                    <tr>
                        <th>Description</th>
                        <th>Done</th>
                    </tr>
                </thead>
                <tbody>
                    <tr><td>练车</td><td>Yes</td></tr>
                    <tr><td>看课外书</td><td>No</td></tr>
                </tbody>
        </table>
        </div>
    </body>
    </html>

    使用MVC模式后代码如下:

    <!DOCTYPE html>
    <html ng-app="todoApp">
    <head>
        <meta charset="UTF-8">
        <title>TO DO List</title>
        <link href="./bootstrap/css/bootstrap.css" rel="stylesheet"/>
        <link href="./bootstrap/css/bootstrap-theme.css" rel="stylesheet"/>
        <script src="./angularJs/angular.js"></script>
        <script>
    
            var model = {
                user:"Yimi",
                items:[{action:"练车",done:true},
                    {action:"看课外书",done:false}]
            };
    
            var todoApp = angular.module("todoApp",[]);
    
            todoApp.controller("ToDoCtrl",function($scope){ //以$开头的变量名表示AngularJS的内置特性
                $scope.todo = model;
            });
    
        </script>
    </head>
    <body ng-controller="ToDoCtrl">
        <div class="page-header">
            <h1>{{todo.user}}'s TO DO List</h1>
            <span class="label label-default">{{todo.items.length}}</span>
        </div>
        <div class="panel">
            <div class="input-group">
                <input class="form-control"/>
                <span class="input-group-btn">
                    <button class="btn btn-default">Add</button>
                </span>
            </div>
            <table class="table table-striped">
                <thead>
                    <tr>
                        <th>Description</th>
                        <th>Done</th>
                    </tr>
                </thead>
                <tbody>
                    <tr ng-repeat="item in todo.items">
                        <td>{{item.action}}</td>
                        <td>{{item.done}}</td>
                    </tr>
                </tbody>
        </table>
        </div>
    </body>
    </html>

    效果图如下:

    模型-视图-控制器(MVC)

    M:模型。程序中的数据

    ......
    var model = {
                user:"Yimi",
                items:[{action:"练车",done:true},
                    {action:"看课外书",done:false}]
            };
    ......

    V:视图。显示数据的逻辑 
    比如在间通过{{和}}调用之前定义的模型的值

    ......
    <h1>{{todo.user}}'s TO DO List</h1>
            <span class="label label-default">{{todo.items.length}}</span>
    ......
    <tr ng-repeat="item in todo.items">
             <td>{{item.action}}</td>
             <td>{{item.done}}</td>
    </tr>
    ......

    C:控制器。对数据进行操作的逻辑

    var todoApp = angular.module("todoApp",[]);
    
            todoApp.controller("ToDoCtrl",function($scope){ //以$开头的变量名表示AngularJS的内置特性
                $scope.todo = model;
            });
    <body ng-controller="ToDoCtrl">
