简单的单页面应用及路由配置的优化

## 未优化的基础单页面应用

<body ng-app="myApp">
    <ul>
        <li><a href="#/find">发现音乐</a></li>
        <li><a href="#/mine">我的音乐</a></li>
        <li><a href="#/friend">我的朋友</a></li>
    </ul>
    <div ng-view>
        
    </div>
    <script src="./libs/angular.js"></script>
    <script src="./libs/angular-route.js"></script>
    <script>
        //一个页面、一个链接对应一个路由
        //module model
        var myApp = angular.module('myApp',['ngRoute']);
        //配置路由
        myApp.config(['$routeProvider',function($routeProvider){
            $routeProvider
                        .when('/find',{
                            templateUrl:'./find.html',
                            controller:'findController'
                        })
                        .when('/mine',{
                            templateUrl:'./mine.html',
                            controller:'mineController'
                        })
                        .when('/friend',{
                            templateUrl:'./friend.html',
                            controller:'friendController'
                        })
        }])


        myApp.controller('findController',['$scope',function($scope){
            $scope.title = '发现音乐';
        }])
        myApp.controller('mineController',['$scope',function($scope){
            $scope.title = '我的音乐';
        }])
        myApp.controller('friendController',['$scope',function($scope){
            $scope.title = '我的朋友';
        }])
    </script>
</body>

## 项目比较大时，把所有的代码全部放在myAPP这个模块上，就可能有点多
## 创建多模块优化

        var friendModule = angular.module('friendModule',[]);
        friendModule.controller('friendController',['$scope',function($scope){
            $scope.title = '我的朋友';
        }])
        var mineModule = angular.module('mineModule',[]);
        mineModule.controller('mineController',['$scope',function($scope){
            $scope.title = '我的音乐';
        }])
        var findModule = angular.module('findModule',[]);
        findModule.controller('findController',['$scope',function($scope){
            $scope.title = '发现音乐';
        }])

## 并添加至myApp中

var myApp = angular.module('myApp',['ngRoute','friendModule','mineModule','findModule']);

## 继续优化

## 创建多个js文件分别存储各模块，例其一

var mineModule = angular.module('mineModule',[]);
mineModule.config(['$routeProvider',function($routeProvider){
            $routeProvider
                        .when('/mine',{
                            templateUrl:'./mine.html',
                            controller:'mineController'
                        })
        }])
        mineModule.controller('mineController',['$scope',function($scope){
            $scope.title = '我的音乐';
        }])

## 引入各模块实现最终优化

<script src="./libs/angular.js"></script>
    <script src="./libs/angular-route.js"></script>
    <script src="./friendModule.js"></script>
    <script src="./mineModule.js"></script>
    <script src="./findModule.js"></script>
    <script>
        var myApp = angular.module('myApp',['ngRoute','friendModule','mineModule','findModule']);
    </script>
