这一讲分为三大模块:
- 一.提取公用的服务层BaseService
- 二.生活模块Tab3的实现
- 三.农业模块Tab4的实现
一.提取公用的服务层BaseService
将doRefresh和loadMore函数封装到BaseService,供其他模块使用。
BaseService的实现
.service('BaseService', function ($http) { this.loadMore = function ($this) { console.log("正在加载更多数据..." + $this.page); $http.get($this.url + "?page=" + $this.page + "&rows=" + settings.rows).success(function (response) { console.log(response); if (response.tngou.length > 0) { $this.items = $this.items.concat(response.tngou); $this.page++; } else { console.log("没有数据了...") $this.isload = true; } $this.callback(); }); } this.doRefresh = function ($this) { console.log("正在执行refresh操作..."); $http.get($this.url + "?page=1&rows=" + settings.rows).success(function (response) { console.log(response); $this.page = 2; $this.items = response.tngou; $this.callback(); $this.isload = false; }); } })
二.生活模块的实现
生活模块的controller实现和service的实现.

1.service层Tab3Service的实现
在Tab3Service中通过依赖注入实现对BaseService的doRefresh和loadMore的调用。
.service('Tab3Service', function (BaseService) { this.getTab3Menu = function () { return [ { name: '社会热点', isload: true, url: server.domain + '/top/list', type: 'top', page: 1, rows: 20, items: [], loadMore: function () { BaseService.loadMore(this); }, doRefresh: function () { BaseService.doRefresh(this); }, callback: function () { //回掉函数 } }, { name: '健康菜谱', isload: true, url: server.domain + '/cook/list', type: 'cook', page: 1, rows: 20, items: [], loadMore: function () { BaseService.loadMore(this); }, doRefresh: function () { BaseService.doRefresh(this); }, callback: function () { //回掉函数 } }, { name: '健康食品', isload: true, url: server.domain + '/food/list', type: 'food', page: 1, rows: 20, items: [], loadMore: function () { BaseService.loadMore(this); }, doRefresh: function () { BaseService.doRefresh(this); }, callback: function () { //回掉函数 } } ] } })2.controller层Tab3Ctrl控制器的实现
.controller('Tab3Ctrl', function ($scope, Tab3Service, $controller, $state, $ionicTabsDelegate) { $scope.classify = Tab3Service.getTab3Menu() $scope.currentTabId = "tab3"; $controller('BaseCtrl', { $scope: $scope }); $scope.goDetails = function (item, type) { var title = "", name = ""; if (item.title) { title += item.title; } if (item.name) { title += item.name; } console.log(item); $state.go('tab.tab3-details', { id: item.id, title: title, type: type }) $ionicTabsDelegate.showBar(false); } })3.tab3.html和tab3-details.html的视图实现
tab3.html
<ion-view view-title="生活"> <ion-slide-box show-pager="false" on-slide-changed="slideChanged($index)"> <ion-slide ng-repeat="slide in slides"> <ion-content> <ion-refresher pulling-text="下拉刷新" on-refresh="slide.doRefresh()"></ion-refresher> <div class="list has-header"> <a ng-repeat="item in slide.items" class="item item-thumbnail-right item-text-wrap" ng-click="goDetails(item,'{{slide.type}}')"> <img ng-src="{{imgUrl+item.img}}" width="30" height="30" alt=""> <h3>{{::item.title+item.name}}</h3> <p>{{::item.description | substring:item.description}}</p> </a> </div> <ion-infinite-scroll ng-if="!slide.isload" on-infinite="slide.loadMore()" distance="1%"> </ion-infinite-scroll> </ion-content> </ion-slide> </ion-slide-box> <ion-tabs id="{{currentTabId}}" class="tabs-striped tabs-top"> <ion-tab ng-repeat="item in tabs" on-select="selectedTab($index)" title="{{item.name}}"></ion-tab> </ion-tabs> </ion-view>tab3-details.html
<ion-view title="{{title}}"> <ion-content class="padding"> <div class="message" > <img ng-src="{{imgUrl+item.img}}" /> <div ng-bind-html="item.message"></div> </div> </ion-content> </ion-view>4.配置路由
在app.js中完善tab3的路由配置
.state('tab.tab3', { url: '/tab3', views: { 'tab3': { templateUrl: 'templates/tab3.html', controller: 'Tab3Ctrl' } } }) .state('tab.tab3-details', { url: '/tab/tab3-details/:id/:title/:type', views: { 'tab3': { templateUrl: 'templates/tab3-details.html', controller: 'Tab1DetailsCtrl' } } })
三.农业模块的实现
生活模块的controller实现和service的实现.
[效果图]
1.service层Tab4Service的实现
在Tab4Service中通过依赖注入实现对BaseService的doRefresh和loadMore的调用。
.service('Tab4Service', function ($http, BaseService) { this.getTab4Menu = function () { return [ { name: '农业新闻', isload: true, url: server.domain + '/news/list', type: 'news', page: 1, rows: 20, items: [], loadMore: function () { BaseService.loadMore(this); }, doRefresh: function () { BaseService.doRefresh(this); }, callback: function () { //回掉函数 } }, { name: '农业技术', isload: true, url: server.domain + '/tech/list', type: 'tech', page: 1, rows: 20, items: [], loadMore: function () { BaseService.loadMore(this); }, doRefresh: function () { BaseService.doRefresh(this); }, callback: function () { //回掉函数 } } ] } this.getDetails = function (type, id) { var url = server.domain + "/" + type + "/show?id=" + id + "&callback=JSON_CALLBACK"; return $http.jsonp(url); } })2.controller层Tab4Ctrl控制器的实现
.controller('Tab4Ctrl', function ($scope, Tab4Service, $controller, $state, $ionicTabsDelegate) { $scope.classify = Tab4Service.getTab4Menu() $scope.currentTabId = "tab4"; $controller('BaseCtrl', { $scope: $scope }); $scope.goDetails = function (item, type) { var title = "", name = ""; if (item.title) { title += item.title; } if (item.name) { title += item.name; } console.log(item); $state.go('tab.tab4-details', { id: item.id, title: title, type: type }) $ionicTabsDelegate.showBar(false); } })3.tab3.html和tab3-details.html的视图实现
tab3.html
<ion-view view-title="生活"> <ion-slide-box show-pager="false" on-slide-changed="slideChanged($index)"> <ion-slide ng-repeat="slide in slides"> <ion-content> <ion-refresher pulling-text="下拉刷新" on-refresh="slide.doRefresh()"></ion-refresher> <div class="list has-header"> <a ng-repeat="item in slide.items" class="item item-thumbnail-right item-text-wrap" ng-click="goDetails(item,'{{slide.type}}')"> <img ng-src="{{imgUrl+item.img}}" width="30" height="30" alt=""> <h3>{{::item.title+item.name}}</h3> <p>{{::item.description | substring:item.description}}</p> </a> </div> <ion-infinite-scroll ng-if="!slide.isload" on-infinite="slide.loadMore()" distance="1%"> </ion-infinite-scroll> </ion-content> </ion-slide> </ion-slide-box> <ion-tabs id="{{currentTabId}}" class="tabs-striped tabs-top"> <ion-tab ng-repeat="item in tabs" on-select="selectedTab($index)" title="{{item.name}}"></ion-tab> </ion-tabs> </ion-view>tab4-details.html
<ion-view title="{{title}}"> <ion-content class="padding"> <div class="message" ng-bind-html="item.message"></div> </ion-content> </ion-view>4.配置路由
在app.js中完善tab4的路由配置
.state('tab.tab4', { url: '/tab4', views: { 'tab4': { templateUrl: 'templates/tab4.html', controller: 'Tab4Ctrl' } } }) .state('tab.tab4-details', { url: '/tab/tab4-details/:id/:title/:type', views: { 'tab4': { templateUrl: 'templates/tab4-details.html', controller: 'Tab1DetailsCtrl' } } })
难点和注意事项
- 理解为什么要封装BaseService
- 每个tab都有自己的tab-details,这么做的原因是各自用各自的路由管理,不会出现页面逻辑混乱。
