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


 
{{default.value}}

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


   
     下拉框触发
   
   

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"。
