1、預期實現效果:html

(項目地址:https://github.com/liyuan-meng/uiRouter-app)github
2、分析題目要求,給出依賴關係,構建項目json
1. service:數組
(1)根據條件查詢people數據checkPeople.service,不給出條件則查詢全部。promise
(2)獲得路由信息getStateParams.service。app
2. components:異步
(1)hello模塊:點擊button按鈕更改內容。ide
(2)peolpleList模塊:顯示people列表,點擊people顯示people詳情。依賴於checkPeople.service模塊。函數
(3)peopleDetail模塊:顯示people詳情,依賴於checkPeople.service模塊和getStateParams.service模塊。
3. 構建項目:
如圖所示:component目錄用來保存全部服務模塊和業務模塊,lib目錄保存外部引用(我是用的是angular.js1.5.8和ui-route0.2.18),app.config.js文件用來配置路由,index.html則做爲入口文件。
3、實現這個例子
1. 首頁index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <script src="./lib/angular.js"></script> <script src="./lib/angular-ui-route.js"></script> <script src="./app.config.js"></script> <script src="./components/core/people/checkPeople.service.js"></script> <script src="./components/core/people/getStateParams.service.js"></script> <script src="./components/hello/hello.component.js"></script> <script src="./components/people-list/people-list.component.js"></script> <script src="./components/people-detail/people-detail.component.js"></script> </head> <body ng-app="helloSolarSystem"> <div> <a ui-sref="helloState">Hello</a> <a ui-sref="aboutState">About</a> <a ui-sref="peopleState">People</a> </div> <ui-view></ui-view> </body> </html>
(1)導入lib中的文件以及全部用到的service和component服務的文件。
(2)ng-app="helloSolarSystem"指明瞭從helloSolarSystem模塊開始解析。
(3)定義視圖<ui-view></ui-view>
2. 配置路由app.config.js
'use strict'; angular.module("helloSolarSystem", ['peopleList', 'peopleDetail', 'hello','ui.router']). config(['$stateProvider', function ($stateProvider) { $stateProvider.state('helloState', { url: '/helloState', template:'<hello></hello>' }).state('aboutState', { url: '/about', template: '<h4>Its the UI-Router Hello Solar System app!</h4>' }).state('peopleState', { url: '/peopleList', template:'<people-list></people-list>' }).state('peopleState.details', { url:'/detail/:id', template: '<people-detail></people-detail>' }) } ]);
(1)模塊名字:helloSolarSystem;
(2)注入'peopleList', 'peopleDetail', 'hello','ui.router'模塊。
(3)配置stateProvider服務的視圖控制,例如第一個名爲helloState的視圖控制器:當ui-sref == "helloState"的時候,路由更新爲url的值#/helloState,而且<ui-view></ui-view>中顯示的內容爲<hello></hello>組件解析出的內容。
(4)嵌套路由的實現:名爲peopleState的視圖控制器是父路由。名爲peopleState.details的視圖控制器是子路由。這是一種相對路由方式,父路由將匹配.../index.html#/peopleState/,子路由將匹配.../index.html#/peopleState/detail/x(x是/detail/:id中的id的值)。若是改爲絕對路由的形式,只須要寫成url:'^/detail/:id',這時子路由將匹配.../index.html#/detail/x(x是/detail/:id中的id的值)。
4. 實現checkPeople.service(根據條件查找people)
checkPeople.sercice.js
'use strict'; //根據條件(參數)查找信息。 angular.module('people.checkPeople', ['ui.router']). factory('CheckPeople', ['$http', function ($http) { return { getData: getData }; function getData(filed) { var people; var promise = $http({ method: 'GET', url: './data/people.json' }).then(function (response) { if (filed) { people = response.data.filter(function (value) { if (Number(value.id) === Number(filed)) { return value; } }) } else { people = response.data; } return people; }); return promise; } }]);
(1)在getData這個函數中,咱們想要返回一個保存people信息的數組,可是因爲使用$http().then()服務的時候,這是一個異步請求,咱們並不知道請求何時結束,因此世界返回people數組是有問題的。咱們注意到,$http().then()是一個Promise對象,因此咱們能夠想到直接將這個對象返回,這樣在就能夠使用"函數的結果.then(function(data))"來獲得異步請求拿來的數據data。
3. 實現getStateParams.service(獲取路由信息)
getStatePatams.service.js
"use strict"; angular.module("getStateParams", ['ui.router']). factory("GetStateParams", ["$location", function ($location) { return { getParams: getParams }; function getParams() { var partUrlArr = $location.url().split("/"); return partUrlArr[partUrlArr.length-1]; } }]);
(1)這裏的getParams函數返回的是路由信息的最後一個數據,也就是people的id,這個service有些特殊,不夠通用,可能還須要優化一下會更加合理。不過並不影響咱們的需求。
4. 實現hello模塊
hello.template.html
<div> <div ng-hide="hideFirstContent">hello solar sytem!</div> <div ng-hide="!hideFirstContent">whats up solar sytem!</div> <button ng-click="ctlButton()">click</button> </div>
hello.component.js
'use strict'; angular.module("hello", []) .component('hello', { templateUrl: './components/hello/hello.template.html', controller: ["$scope", function HelloController($scope) { $scope.hideFirstContent = false; $scope.ctlButton = function () { this.hideFirstContent = !this.hideFirstContent; }; } ] });
5. 實現peolpeList模塊:
peopleList.template.html
<div> <ul> <a ng-repeat="item in people" ui-sref="peopleState.details({id:item.id})"> <li>{{item.name}}</li> </a> </ul> <ui-view></ui-view> </div>
(1)這裏的<ui-view></ui-view>用來顯示peopleList的子組件pepleDetail
peopleList.component.js
'use strict'; angular.module("peopleList", ['people.checkPeople']) .component('peopleList', { templateUrl: './components/people-list/people-list.template.html', controller: ['CheckPeople','$scope', function PeopleListController(CheckPeople, $scope) { $scope.people = []; CheckPeople.getData().then(function(data){ $scope.people = data; }); } ] });
6. 實現peopleDetail模塊
peopleDetail.template.html
<ul ng-repeat="item in peopleDetails track by $index"> <li>名字: {{item.name}}</li> <li>介紹: {{item.intro}}</li> </ul>
peopleDetail.component.js
'use strict'; angular.module("peopleDetail", ['people.checkPeople', 'getStateParams']) .component('peopleDetail', { templateUrl: './components/people-detail/people-detail.template.html', controller: ['CheckPeople', 'GetStateParams', '$scope', function peopleDetailController(CheckPeople, GetStateParams, $scope) { $scope.peopleDetails = []; CheckPeople.getData(GetStateParams.getParams()).then(function(data){ $scope.peopleDetails = data; }); } ] });
