1. Common attributes:

ng -app: can be used on any element, represents the angular application scope, and is also the program entry point of AngularJS. It initializes the elements within the tag.

ng-controller: Controller.

ng- model: Specifies that the current element is bound to the attribute in the data model ($scope). If there is no such attribute in the data model, it will be created custom

ng-repeat: Loop the attributes in $scope.

ng-bind or {{attribute name}}: Get the attribute value.

2. Two-way binding:

Definition: Updating the view will automatically follow the new model, and updating the model will Automatically update the view.

<!-- Angular编程入口 -->
<body ng-app>
    <p>
        <!-- 模型 -->
        <input type="text" name="name" ng-model="name " />
    </p>
    <p>
        Hello,{{name}}!!! 
    </p>
</body>

3. AngularJS implements MVC based on modularization:

<body>
    <!-- Angular编程入口,定义一个模块 -->
    <p ng-app="myapp" ng-controller="myctrl">
        <p>
            <!-- 模型 -->
            <input type="text" name="name" ng-model="name " />
        </p>
        <p>
            Hello,{{name}}!!! 
        </p>
    </p>
</body>
<script type="text/javascript">
    //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组
    var myapp = angular.module("myapp",[]);
		
    //定义模块的控制器
    /*myapp.controller("myctrl",["$scope",function($scope){
        $scope.name="沃德发";
    }])*/
		
    //$scope页面与控制器的桥梁
    myapp.controller("myctrl",function($scope){
        $scope.name="法克鱿";
    });
</script>

4. AngularJS event binding:

ng-click: AngularJS click event .

<body>
    <!-- Angular编程入口,定义一个模块 -->
    <p ng-app="myapp" ng-controller="myctrl">
        <p>
            <!-- 模型 -->
            <input type="text" name="name" ng-model="name " />
            <input type="button" value="清空" ng-click="clearVal()"/>
        </p>
        <p>
            Hello,{{name}}!!! 
        </p>
    </p>
</body>
<script type="text/javascript">
    //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组
    var myapp = angular.module("myapp",[]);
		
    //$scope页面与控制器的桥梁
    myapp.controller("myctrl",function($scope){
        $scope.name="嗯嗯啊";
        //事件绑定
        $scope.clearVal = function() {
            $scope.name = "";
        }
    });
</script>

5. Traversing collections of AngularJS:

ng-repeat: AngularJS is used for collection traversal and iteration.

<body>
    <!-- Angular编程入口,定义一个模块 -->
    <p ng-app="myapp" ng-controller="myctrl">
        <table border="1" width="90%">
            <tr>
                <td>序号</td>
                <td>商品编号</td>
                <td>商品名称</td>
                <td>商品价格</td>
            </tr>	
            <tr ng-repeat="product in products">
                <td>{{$index+1}}</td>
                <td>{{product.id}}</td>
                <td>{{product.name}}</td>
                <td>{{product.price}}</td>
            </tr>
        </table>
    </p>
</body>
<script type="text/javascript">
    //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组
    var myapp = angular.module("myapp",[]);		
    myapp.controller("myctrl",function($scope){
        $scope.products=[
            {
                id:&#39;A001&#39;,
                name:&#39;狗子&#39;,
                price:3306
            },{
                id:&#39;A002&#39;,
                name:&#39;啥子哟&#39;,
                price:8080
            }			
        ]			
    });

6. Routing of AngularJS:

JS for introducing routing:

<script type="text/javascript" src="../js/angular-route.min.js" ></script>

ng-view: Display the page called by routing

$routeProvider: Routing system

when..when..otherwise : Similar to switch..case..case..default

<!-- Angular编程入口 -->
<body ng-app="myapp">
    <p>
        <h1>HEAD</h1>
        <a href="#/aa">首页</a>
        <a href="#/bb">*</a>
        <a href="#/cc">站长推荐</a>
    </p>
    <!-- ng-view显示路由调用页面 -->
    <p ng-view>			
    </p>
    <p>
        <h1>FOOT</h1>
    </p>
</body>
	
<script type="text/javascript">
    var myapp = angular.module("myapp",["ngRoute"]);
		
    myapp.config(["$routeProvider",function($routeProvider){
        $routeProvider.when("/aa",{
            templateUrl:&#39;aa.html&#39;
        }).when("/bb",{
            templateUrl:&#39;bb.html&#39;
        }).when("/cc",{
            templateUrl:&#39;5_3.html&#39;
        }).otherwise({
            redirectTo:"/"
        });
