本篇內容介紹了“Angular項目構建的方法是什么”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
(1) 不用requirejs直接構建Angular
之所以不使用requirejs就直接構建angular,因為angular對于依賴的管理以及angular的使用場景完全可以做到這一點.首先在以來上,angular的依賴注入是個好東西,不了解的同學可以去搜一下資料.我這里簡單的說,就是當我需要一個module的時候,我不用管它在哪,它是什么.我只要知道它的名字然后告訴angular就可以了,至于怎么將它的對象傳遞過來,怎么找到的,angular自己會去處理.
angular.module('myApp', [ 'ngRoute', ]);例如這里的ngRoute,我需要知道ngRoute怎么來的,在哪里.只要有一個模塊定義為ngRoute我就可以直接拿來用。
鑒于Angular如此的給力,剩下的事情就好辦了.我們只需要從功能和業務兩方面將文件劃分成module就可以了,然后將所有的庫文件在頁面上通過script標簽引用,再將所有的業務文件也即是我們自己寫的js合并為一個all.js加載到頁面上即可。
這里文件的劃分遵循angular官方的推薦方式：
|--js |--app.js // app啟動文件,用于app配置 |--controllers.js // controllers也就是存放我們自己的業務文件 |--directives.js // 指令文件(指令可共用) |--fliters.js // 過濾器文件(過濾器可共用) |--services.js // 服務文件(可共用,一般是與服務器交互的服務) |--partials |--html1.html |--html2.html |--index.html
app.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'}); $routeProvider.otherwise({redirectTo: '/view1'}); }]);controllers.js
'use strict'; /* Controllers */ angular.module('myApp.controllers', []) .controller('MyCtrl1', ['$scope', function($scope) { }]) .controller('MyCtrl2', ['$scope', function($scope) { }]);directives.js
'use strict'; /* Directives */ angular.module('myApp.directives', []). directive('appVersion', ['version', function(version) { return function(scope, elm, attrs) { elm.text(version); }; }]);filters.js
'use strict'; /* Filters */ angular.module('myApp.filters', []). filter('interpolate', ['version', function(version) { return function(text) { return String(text).replace(/\%VERSION\%/mg, version); }; }]);services.js
'use strict'; /* Services */ // 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,項目就構建完成了.還有幾個補充點就是其一你可以將controllers繼續拆分為多個controller模塊,這里可以完全按照你的業務進行劃分.比如user目錄下userController等等.然后將所有這些我們自己寫的文件通過grunt或者gulp進行合并為一個單獨的總的文件all.js這樣在頁面中除了庫文件只要這一個文件就行了.angular的module所帶來的好處就是這樣合并的文件,不用在乎js合并的順序,因為它是通過angular依賴注入的。
(2) 通過requirejs構建
這種方式的構建可能對于某些人來講更加清晰,結構和上面的基本一樣,多了一個man.js用來配置requirejs,單獨拆分出routes.js以及一個controller文件夾通過requirejs將controller一個個拆分出來,按需的異步加載。
