本篇内容介绍了“Angular项目构建的方法是什么”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
(1) 不用requirejs直接构建Angular
之所以不使用requirejs就直接构建angular,因为angular对于依赖的管理以及angular的使用场景完全可以做到这一点.首先在以来上,angular的依赖注入是个好东西,不了解的同学可以去搜一下资料.我这里简单的说,就是当我需要一个module的时候,我不用管它在哪,它是什么.我只要知道它的名字然后告诉angular就可以了,至于怎么将它的对象传递过来,怎么找到的,angular自己会去处理.
angular.module('myApp', [ 'ngRoute', ]);例如这里的ngRoute,我需要知道ngRoute怎么来的,在哪里.只要有一个模块定义为ngRoute我就可以直接拿来用。
鉴于Angular如此的给力,剩下的事情就好办了.我们只需要从功能和业务两方面将文件划分成module就可以了,然后将所有的库文件在页面上通过script标签引用,再将所有的业务文件也即是我们自己写的js合并为一个all.js加载到页面上即可。
这里文件的划分遵循angular官方的推荐方式：
|--js
|--app.js // app启动文件,用于app配置
|--controllers.js // controllers也就是存放我们自己的业务文件
|--directives.js // 指令文件(指令可共用)
|--fliters.js // 过滤器文件(过滤器可共用)
|--services.js // 服务文件(可共用,一般是与服务器交互的服务)
|--partials
|--html1.html
|--html2.html
|--index.htmlapp.js
'use strict'; // Declare app level module which depends on filters, and services angular.module('myApp', [ 'ngRoute', 'myApp.filters', 'myApp.services', 'myApp.directives', 'myApp.controllers' ]). config(['$routeProvider', function($routeProvider) { $routeProvider.when('/view1', {templateUrl: 'partials/partial1.html', controller: 'MyCtrl1'}); $routeProvider.when('/view2', {templateUrl: 'partials/partial2.html', controller: 'MyCtrl2'}); $routeProvider.otherwise({redirectTo: '/view1'}); }]);controllers.js
'use strict'; angular.module('myApp.controllers', []) .controller('MyCtrl1', ['$scope', function($scope) { }]) .controller('MyCtrl2', ['$scope', function($scope) { }]);directives.js
'use strict'; angular.module('myApp.directives', []). directive('appVersion', ['version', function(version) { return function(scope, elm, attrs) { elm.text(version); }; }]);filters.js
'use strict'; angular.module('myApp.filters', []). filter('interpolate', ['version', function(version) { return function(text) { return String(text).replace(/\%VERSION\%/mg, version); }; }]);services.js
'use strict'; // Demonstrate how to register services // In this case it is a simple value service. angular.module('myApp.services', []). value('version', '0.1');index.html
<!DOCTYPE html> <!--[if lt IE 7]> <html ng-app="myApp" class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]--> <!--[if IE 7]> <html ng-app="myApp" class="no-js lt-ie9 lt-ie8"> <![endif]--> <!--[if IE 8]> <html ng-app="myApp" class="no-js lt-ie9"> <![endif]--> <!--[if gt IE 8]><!--> <html ng-app="myApp"> <!--<![endif]--> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title>My AngularJS App</title> <meta name="description" content=""> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="bower_components/html5-boilerplate/css/normalize.css"> <link rel="stylesheet" href="bower_components/html5-boilerplate/css/main.css"> <link rel="stylesheet" href="css/app.css"/> <script src="bower_components/html5-boilerplate/js/vendor/modernizr-2.6.2.min.js"></script> </head> <body> <ul> <li><a href="#/view1">view1</a></li> <li><a href="#/view2">view2</a></li> </ul> <!--[if lt IE 7]> <p>You are using an <strong>outdated</strong> browser. Please <a href="http://browsehappy.com/">upgrade your browser</a> to improve your experience.</p> <![endif]--> <div ng-view></div> <div>Angular seed app: v<span app-version></span></div> <!-- In production use: <script src="//ajax.googleapis.com/ajax/libs/angularjs/x.x.x/angular.min.js"></script> --> <script src="bower_components/angular/angular.js"></script> <script src="bower_components/angular-route/angular-route.js"></script> <script src="js/app.js"></script> <script src="js/services.js"></script> <script src="js/controllers.js"></script> <script src="js/filters.js"></script> <script src="js/directives.js"></script> </body> </html>如此在不使用requirejs的情景下,项目就构建完成了.还有几个补充点就是其一你可以将controllers继续拆分为多个controller模块,这里可以完全按照你的业务进行划分.比如user目录下userController等等.然后将所有这些我们自己写的文件通过grunt或者gulp进行合并为一个单独的总的文件all.js这样在页面中除了库文件只要这一个文件就行了.angular的module所带来的好处就是这样合并的文件,不用在乎js合并的顺序,因为它是通过angular依赖注入的。
(2) 通过requirejs构建
这种方式的构建可能对于某些人来讲更加清晰,结构和上面的基本一样,多了一个man.js用来配置requirejs,单独拆分出routes.js以及一个controller文件夹通过requirejs将controller一个个拆分出来,按需的异步加载。

define([], function() { return ['$scope', '$http', function($scope, $http) { // You can access the scope of the controller from here $scope.welcomeMessage = 'hey this is myctrl2.js!'; // because this has happened asynchroneusly we've missed // Angular's initial call to $apply after the controller has been loaded // hence we need to explicityly call it at the end of our Controller constructor $scope.$apply(); }]; });“Angular项目构建的方法是什么”的内容就介绍到这里了，感谢大家的阅读。如果想了解更多行业相关的知识可以关注编程网网站，小编将为大家输出更多高质量的实用文章！
