学习要点:
- 控制器模块化
- 指令模块化
- 过滤器模块化
- 服务模块化
- 定义值模块化
- 使用模块工作
第一步:创建一个模块
// function : define module named exampleApp // param detail : // param one : module name // param two : relay on modules collection // parms three : config information var myApp = angular.module("exampleApp", ["exampleApp.Controllers", ["exampleApp.Controllers", "exampleApp.Filters", "exampleApp.Directives", "exampleApp.Service", "exampleApp.Values"])
在视图中应用模块
<!-- use module --> <html ng-app="exampleApp"> ... </html>
第二步:定义值
var valueModule = angular.module("exampleApp.Values", []) // defind value var now = new Date(); valueModule.value("nowValue", now);
第三步:定义服务
var serviceModule = angular.module("exampleApp.Service", []) // function : define a service named days serviceModule.service("days", function (nowValue) { this.today = nowValue.getDay(); this.tomorrow = this.today + 1; })
第四步:定义控制器
var controllerModule = angular.module("exampleApp.Controllers", []); // function : define a controller named dayCtrl // the controller include two param: // param detail: // param one : name of controller // param two : a factory function // the param $scope of factory function show information to view controllerModule.controller("dayCtrl", function ($scope, days) { // days : use custom service // today is ... $scope.day = days.today; // tomorrow is ... $scope.tomorrow = 7; })
将控制器应用于视图
<!-- use controller --> <div class="panel" ng-controller="dayCtrl"> <div class="panel-header"> <h3>Angular App</h3> </div> <!-- if the day is undefined, show unknow --> <!-- use filter and data binding --> <h4>Today is {{ day || "unknow" }}</h4> <h4>Tomorrow is {{ tomorrow || "unknow" }}</h4> </div>
第五步:定义指令
var directiveModule = angular.module("exampleApp.Directives", []); // function : define a directive named highlight // it accepts two param // param one : the name of directive // param two : a factory method directiveModule.directive("highlight", function ($filter) { // get the filter function var dayFilter = $filter("dayName"); // param detail: // scope : view scope of action // element : the element which uses the custom directive // attrs : the attrs of the element return function (scope, element, attrs) { // console.log(dayFilter(scope.day)); if (dayFilter(scope.day) == attrs['highlight']) { element.css("color", 'red'); } } })
将指令应用于视图
... <h4 highlight="Saturday">Today is {{ day || "unknow" | dayName }}</h4> ...
第六步:定义过滤器
var filterModule = angular.module("exampleApp.Filters", []); // function : define a fitler named dayName filterModule.filter('dayName', function () { var dayNames = ['Sunday', "Monday", 'Tuesday', 'Wednesday', 'Thurday', 'Friday', 'Saturday']; return function (input) { // input is the value of data binding return angular.isNumber(input % 7) ? dayNames[input % 7] : input % 7; }; })
将过滤器应用于视图
<!-- 用 | 分开 --> <h4 highlight="Saturday">Today is {{ day || "unknow" | dayName }}</h4> <h4>Tomorrow is {{ tomorrow || "unknow" | dayName }}</h4>
最后,下面是完整的代码:
文件一:example.html
<!DOCTYPE> <!-- use module --> <html ng-app="exampleApp"> <head> <title>Angluar test</title> <meta charset="utf-8"/> <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" rel="external nofollow" > <link rel="stylesheet" type="text/css" href="css/bootstrap-theme.min.css" rel="external nofollow" > </head> <body> <!-- use controller --> <div class="panel" ng-controller="dayCtrl"> <div class="panel-header"> <h3>Angular App</h3> </div> <!-- if the day is undefined, show unknow --> <!-- use defined directive "highlight" --> <!-- use filter and data binding --> <h4 highlight="Saturday">Today is {{ day || "unknow" | dayName }}</h4> <h4>Tomorrow is {{ tomorrow || "unknow" | dayName }}</h4> </div> <script type="text/javascript" src="js/angular.min.js"></script> <script type="text/javascript" src="values/exampleValue.js"></script> <script type="text/javascript" src="controllers/exampleController.js"></script> <script type="text/javascript" src="filters/exampleFilter.js"></script> <script type="text/javascript" src="directives/exampleDirective.js"></script> <script type="text/javascript" src="services/exampleService.js"></script> <script type="text/javascript"> // function : define module named exampleApp // param detail : // param one : module name // param two : relay on modules collection // parms three : config information var myApp = angular.module("exampleApp", ["exampleApp.Controllers", "exampleApp.Filters", "exampleApp.Directives", "exampleApp.Service", "exampleApp.Values"]) </script> </body> </html>
文件二:services/exampleService.js
var serviceModule = angular.module("exampleApp.Service", []) // function : define a service named days serviceModule.service("days", function (nowValue) { this.today = nowValue.getDay(); this.tomorrow = this.today + 1; })
文件三:values/exampleValue.js
var valueModule = angular.module("exampleApp.Values", []) // defind value var now = new Date(); valueModule.value("nowValue", now);
文件四:directives/exampleDirective.js
var directiveModule = angular.module("exampleApp.Directives", []); // function : define a directive named highlight // it accepts two param // param one : the name of directive // param two : a factory method directiveModule.directive("highlight", function ($filter) { // get the filter function var dayFilter = $filter("dayName"); // param detail: // scope : view scope of action // element : the element which uses the custom directive // attrs : the attrs of the element return function (scope, element, attrs) { // console.log(dayFilter(scope.day)); if (dayFilter(scope.day) == attrs['highlight']) { element.css("color", 'red'); } } })
文件五:controllers/exampleController.js
var controllerModule = angular.module("exampleApp.Controllers", []); // function : define a controller named dayCtrl // the controller include two param: // param detail: // param one : name of controller // param two : a factory function // the param $scope of factory function show information to view controllerModule.controller("dayCtrl", function ($scope, days) { // days : use custom service // today is ... $scope.day = days.today; // tomorrow is ... $scope.tomorrow = days.tomorrow; })
文件六:filters/exampleFilter.js
var filterModule = angular.module("exampleApp.Filters", []); // function : define a fitler named dayName filterModule.filter('dayName', function () { var dayNames = ['Sunday', "Monday", 'Tuesday', 'Wednesday', 'Thurday', 'Friday', 'Saturday']; return function (input) { // input is the value of data binding return angular.isNumber(input % 7) ? dayNames[input % 7] : input % 7; }; })
