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
...
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 ...
$scope.tomorrow = 7;
})将控制器应用于视图
Angular App
Today is {{ day || "unknow" }}
Tomorrow is {{ tomorrow || "unknow" }}
第五步：定义指令
var directiveModule = angular.module("exampleApp.Directives", []);
// function : define a directive named highlight
// it accepts two param
// param one : the name of directive
// param two : a factory method
directiveModule.directive("highlight", function ($filter) {
// get the filter function
var dayFilter = $filter("dayName");
// param detail:
// scope : view scope of action
// element : the element which uses the custom directive
// attrs : the attrs of the element
return function (scope, element, attrs) {
// console.log(dayFilter(scope.day));
if (dayFilter(scope.day) == attrs['highlight']) {
element.css("color", 'red');
}
}
})
将指令应用于视图
...Today is {{ day || "unknow" | dayName }}
...
第六步：定义过滤器
var filterModule = angular.module("exampleApp.Filters", []);
// function : define a fitler named dayName
filterModule.filter('dayName', function () {
var dayNames = ['Sunday', "Monday", 'Tuesday', 'Wednesday', 'Thurday', 'Friday', 'Saturday'];
return function (input) {
// input is the value of data binding
return angular.isNumber(input % 7) ? dayNames[input % 7] : input % 7;
};
})
将过滤器应用于视图
Today is {{ day || "unknow" | dayName }}
Tomorrow is {{ tomorrow || "unknow" | dayName }}
最后，下面是完整的代码：
文件一：example.html
Angluar test Angular App
Today is {{ day || "unknow" | dayName }}
Tomorrow is {{ tomorrow || "unknow" | dayName }}
文件二：services/exampleService.js
var serviceModule = angular.module("exampleApp.Service", [])
// function : define a service named days
serviceModule.service("days", function (nowValue) {
this.today = nowValue.getDay();
this.tomorrow = this.today + 1;
})文件三：values/exampleValue.js
var valueModule = angular.module("exampleApp.Values", [])
// defind value
var now = new Date();
valueModule.value("nowValue", now);
文件四：directives/exampleDirective.js
var directiveModule = angular.module("exampleApp.Directives", []);
// function : define a directive named highlight
// it accepts two param
// param one : the name of directive
// param two : a factory method
directiveModule.directive("highlight", function ($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;
};
})
