在AngularJs中设置全局常量

问题描述

我正在尝试为应用程序在angular js中创建常量js文件。我正在使用以下代码为整个应用程序实现常量。

I am trying to create constants js file in angular js for an application. I am using below code to implement constants for entire application. It's working fine.

<code>
// app.js
angular.module('myApp', [
        'ngCookies',
        'ngResource',
        'ngSanitize',
        'ngRoute'
    ])
    .constant('config', {
        mySetting: 42
    })
    .config(function ($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'views/main.html',
                controller: 'MainCtrl'
            })
            .otherwise({
                redirectTo: '/'
            });
    });
</code>

我关心的是app.js文件，我只想写路由，要写的常量单独的文件，我将为应用程序中的所有控制器调用同一文件。

My concern is in app.js file I want to write only routing, for constants I want to write separate file and I will call same file for all the controllers in my application.

对于整个应用程序，我可能要声明200个以上的常量，因此我想使它成为单独的文件或为控制器明智地拆分常量文件。

For entire application might be 200+ constants I want to declare, so I want to make it is separate file or split constants file for controllers wise.

请指导我哪种方法易于维护。

Please guide me which way is easy for maintenance.

预先感谢

推荐答案

您还可以通过使用另一个模块来处理所有常量，工厂，服务或价值来维护单独的文件。为了处理您的常量，下面的代码将给您和提示

You can also maintain a separate file by using another module to handle all your constant, factory, services or value. To handle your constants the below code will give you and idea

例如：

包括您的 app.js 文件，然后是您的 constant.js 脚本文件

include your app.js file after that your constant.js script file

var myApp = angular.module("myApp", ['myConstants']); //constants module injection
myApp.controller("myController", ["$scope", "myValue", function() {
....
}]);

在您的constant.js中

in your constant.js

angular.module("myConstants", []).constant('myValue', 'The value');
