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:



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:

使用Chrome浏览器查看



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">
