AngularJs 动态加载模块和依赖
我们都学习过AngularJS,本来一直想要深入研究的,但是由于工作等等的原因,总是断断续续的学习,一直掌握不了精髓所在,话不多说,今天爱站技术频道小编给大家带来了AngularJs 动态加载模块和依赖,希望对你学习这方面知识有所帮助。
为了实现这篇学习笔记知识点的效果,我们需要用到:
angular:https://github.com/angular/angular.js
ui-router:https://github.com/angular-ui/ui-router
ocLazyLoad:https://github.com/ocombe/ocLazyLoad
废话不多说,进入正题...
首先我们看下文件结构:
Angular-ocLazyLoad --- demo文件夹 Scripts --- 框架及插件文件夹 angular-1.4.7 --- angular 不解释 angular-ui-router --- uirouter 不解释 oclazyload --- ocLazyload 不解释 bootstrap --- bootstrap 不解释 angular-tree-control-master --- angular-tree-control-master 不解释 ng-table --- ng-table 不解释 angular-bootstrap --- angular-bootstrap 不解释 js --- js文件夹 针对demo写的js文件 controllers --- 页面控制器文件夹 angular-tree-control.js --- angular-tree-control控制器代码 default.js --- default控制器代码 ng-table.js --- ng-table控制器代码 app.config.js --- 模块注册及配置代码 oclazyload.config.js --- 加载模块配置代码 route.config.js --- 路由配置及加载代码 views --- html页面文件夹 angular-tree-control.html --- angular-tree-control插件的效果页面 default.html --- default页面 ng-table.html --- ng-table插件效果页面 ui-bootstrap.html --- uibootstrap插件效果页面 index.html --- 主页面
注意:这个demo没做嵌套路由,只是简单实现单视图的路由以展示效果。
我们来看主页面的代码:
在这个页面,我们只加载了bootstrap的css、angular的js、ui-router的js、ocLazyLoad的js,以及3个配置的js文件。
再看看四个页面的html代码:
angular-tree-control效果页面
{{node.title}}
页面上有个使用该插件对应的指令。
default页面
这里我们只是用来证明加载并正确执行default.js。
ng-table效果页面
ng-table
Sorting: {{ngtable.tableParams.sorting()|json}}
{{user.name}} | {{user.age}} |
这里写了些简单的ng-table效果。
ui-bootstrap效果页面
这里仅写了个下拉框效果,证明正确加载并使用该插件。
好了,看完了html,我们看下加载配置和路由配置:
"use strict" var tempApp = angular.module("templateApp",["ui.router","oc.lazyLoad"]) .config(["$provide","$compileProvider","$controllerProvider","$filterProvider", function($provide,$compileProvider,$controllerProvider,$filterProvider){ tempApp.controller = $controllerProvider.register; tempApp.directive = $compileProvider.directive; tempApp.filter = $filterProvider.register; tempApp.factory = $provide.factory; tempApp.service =$provide.service; tempApp.constant = $provide.constant; }]);
以上代码对模块的注册,仅仅依赖了ui.router和oc.LazyLoad。配置也只是简单配置了模块,以便在后面的js能识别到tempApp上的方法。
然后我们再看看ocLazyLoad加载模块的配置:
"use strict" tempApp .constant("Modules_Config",[ { name:"ngTable", module:true, files:[ "Scripts/ng-table/dist/ng-table.min.css", "Scripts/ng-table/dist/ng-table.min.js" ] }, { name:"ui.bootstrap", module:true, files:[ "Scripts/angular-bootstrap/ui-bootstrap-tpls-0.14.3.min.js" ] }, { name:"treeControl", module:true, files:[ "Scripts/angular-tree-control-master/css/tree-control.css", "Scripts/angular-tree-control-master/css/tree-control-attribute.css", "Scripts/angular-tree-control-master/angular-tree-control.js" ] } ]) .config(["$ocLazyLoadProvider","Modules_Config",routeFn]); function routeFn($ocLazyLoadProvider,Modules_Config){ $ocLazyLoadProvider.config({ debug:false, events:false, modules:Modules_Config }); };
路由的配置:
"use strict" tempApp.config(["$stateProvider","$urlRouterProvider",routeFn]); function routeFn($stateProvider,$urlRouterProvider){ $urlRouterProvider.otherwise("/default"); $stateProvider .state("default",{ url:"/default", templateUrl:"views/default.html", controller:"defaultCtrl", controllerAs:"default", resolve:{ deps:["$ocLazyLoad",function($ocLazyLoad){ return $ocLazyLoad.load("js/controllers/default.js"); }] } }) .state("uibootstrap",{ url:"/uibootstrap", templateUrl:"views/ui-bootstrap.html", resolve:{ deps:["$ocLazyLoad",function($ocLazyLoad){ return $ocLazyLoad.load("ui.bootstrap"); }] } }) .state("ngtable",{ url:"/ngtable", templateUrl:"views/ng-table.html", controller:"ngTableCtrl", controllerAs:"ngtable", resolve:{ deps:["$ocLazyLoad",function($ocLazyLoad){ return $ocLazyLoad.load("ngTable").then( function(){ return $ocLazyLoad.load("js/controllers/ng-table.js"); } ); }] } }) .state("ngtree",{ url:"/ngtree", templateUrl:"views/angular-tree-control.html", controller:"ngTreeCtrl", controllerAs:"ngtree", resolve:{ deps:["$ocLazyLoad",function($ocLazyLoad){ return $ocLazyLoad.load("treeControl").then( function(){ return $ocLazyLoad.load("js/controllers/angular-tree-control.js"); } ); }] } }) };
ui-bootstrap的下拉框简单的实现不需要控制器,那么我们就只看看ng-table和angular-tree-control的控制器js吧:
ng-table.js
(function(){ "use strict" tempApp .controller("ngTableCtrl",["$location","NgTableParams","$filter",ngTableCtrlFn]); function ngTableCtrlFn($location,NgTableParams,$filter){ //数据 var data = [{ name: "Moroni", age: 50 }, { name: "Tiancum ", age: 43 }, { name: "Jacob", age: 27 }, { name: "Nephi", age: 29 }, { name: "Enos", age: 34 }, { name: "Tiancum", age: 43 }, { name: "Jacob", age: 27 }, { name: "Nephi", age: 29 }, { name: "Enos", age: 34 }, { name: "Tiancum", age: 43 }, { name: "Jacob", age: 27 }, { name: "Nephi", age: 29 }, { name: "Enos", age: 34 }, { name: "Tiancum", age: 43 }, { name: "Jacob", age: 27 }, { name: "Nephi", age: 29 }, { name: "Enos", age: 34 }]; this.tableParams = new NgTableParams( // 合并默认的配置和url参数 angular.extend({ page: 1, // 第一页 count: 10, // 每页的数据量 sorting: { name: 'asc' // 默认排序 } }, $location.search()) ,{ total: data.length, // 数据总数 getData: function ($defer, params) { $location.search(params.url()); // 将参数放到url上,实现刷新页面不会跳回第一页和默认配置 var orderedData = params.sorting ? $filter('orderBy')(data, params.orderBy()) :data; $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count())); } } ); }; })();
angular-tree-control.js
(function(){ "use strict" tempApp .controller("ngTreeCtrl",ngTreeCtrlFn); function ngTreeCtrlFn(){ //树数据 this.treeData = [ { id:"1", title:"标签1", childList:[ { id:"1-1", title:"子级1", childList:[ { id:"1-1-1", title:"再子级1", childList:[] } ] }, { id:"1-2", title:"子级2", childList:[ { id:"1-2-1", title:"再子级2", childList:[ { id:"1-2-1-1", title:"再再子级1", childList:[] } ] } ] }, { id:"1-3", title:"子级3", childList:[] } ] }, { id:"2", title:"标签2", childList:[ { id:"2-1", title:"子级1", childList:[] }, { id:"2-2", title:"子级2", childList:[] }, { id:"2-3", title:"子级3", childList:[] } ]} , { id:"3", title:"标签3", childList:[ { id:"3-1", title:"子级1", childList:[] }, { id:"3-2", title:"子级2", childList:[] }, { id:"3-3", title:"子级3", childList:[] } ] } ]; //树配置 this.treeOptions = { nodeChildren:"childList", dirSelectable:false }; }; })();
让我们忽略default.js吧,毕竟里面只有个"Hello Wrold"。
