1. Angularjs MVC
Model:数据模型层
View:视图层,负责展示
Controller:业务逻辑和控制逻辑
优点:代码模块化 代码逻辑比较清晰、可移值性高,后期维护方便、代码复用,
代码规模越来越大的时候,切分职责是大势所趋
缺点:运行效率稍微低一些
2.Angularjs $scope作用域
1.$scope多控制器单独作用域
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script type="text/javascript" src="angular.min.js"></script>
</head>
<body>
<div ng-app="myApp">
<div ng-controller="firstController">{{name}}</div>
<div ng-controller="secondController">{{name}}</div>
</div>
<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller('firstController',function($scope){$scope.name='张三'; });
app.controller('secondController',function($scope){ $scope.name='李四';});
</script>
</body>

2.$rootScope服务
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="../angular.min.js"/>
</head>
<body>
<div ng-app="myApp">
<div ng-controller="firstController">
姓名:{{name}} </br>
年龄:{{age}}</div>
<div ng-controller="secondController">
姓名:{{name}}</br>
年龄:{{age}}
</div>
</div>
<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller('firstController',function($scope,$rootScope){
$scope.name='张三';
$rootScope.age='30';
});
app.controller('secondController',function($scope){
$scope.name='李四';
})
</script>
</body>
</html>
3.Angularjs模块的run方法
run方法初始化全局的数据,只对全局作用域起作用 如$rootScope
<script type="text/javascript">
var test = angular.module('myApp',[]);
test.run(['$rootScope',function($rootScope){
$rootScope.name = 'hello world';
}]);
console.log(test);
</script>
