學習要點：
第一步：創建一個模塊
// function : define module named exampleApp// param detail :// param one : module name// param two : relay on modules collection// parms three : config informationvar myApp = angular.module("exampleApp", ["exampleApp.Controllers", ["exampleApp.Controllers", "exampleApp.Filters", "exampleApp.Directives", "exampleApp.Service", "exampleApp.Values"])在視圖中應用模塊
<!-- use module --><html ng-app="exampleApp"> ...</html>
第二步：定義值
var valueModule = angular.module("exampleApp.Values", [])// defind valuevar now = new Date();valueModule.value("nowValue", now);第三步：定義服務
var serviceModule = angular.module("exampleApp.Service", [])// function : define a service named daysserviceModule.service("days", function (nowValue) { this.today = nowValue.getDay(); this.tomorrow = this.today + 1; })第四步：定義控制器
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 $scope of factory function show information to viewcontrollerModule.controller("dayCtrl", function ($scope, days) { // days : use custom service // today is ... $scope.day = days.today; // tomorrow is ... $scope.tomorrow = 7;})將控制器應用于視圖
<!-- use controller --> <div class="panel" ng-controller="dayCtrl"> <div class="panel-header"> <h3>Angular App</h3> </div> <!-- if the day is undefined, show unknow --> <!-- use filter and data binding --> <h4>Today is {{ day || "unknow" }}</h4> <h4>Tomorrow is {{ tomorrow || "unknow" }}</h4> </div>第五步：定義指令
var directiveModule = angular.module("exampleApp.Directives", []);// function : define a directive named highlight// it accepts two param// param one : the name of directive // param two : a factory methoddirectiveModule.directive("highlight", function ($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'); } } })將指令應用于視圖
...<h4 highlight="Saturday">Today is {{ day || "unknow" | dayName }}</h4>...第六步：定義過濾器
var filterModule = angular.module("exampleApp.Filters", []);// function : define a fitler named dayNamefilterModule.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; };})將過濾器應用于視圖
<!-- 用 | 分開 --><h4 highlight="Saturday">Today is {{ day || "unknow" | dayName }}</h4><h4>Tomorrow is {{ tomorrow || "unknow" | dayName }}</h4>最后，下面是完整的代碼：
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 informationvar 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 daysserviceModule.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 valuevar 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 methoddirectiveModule.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 $scope of factory function show information to viewcontrollerModule.controller("dayCtrl", function ($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 dayNamefilterModule.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; };})以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
