這篇文章主要為大家介紹了AngularJs動(dòng)態(tài)加載模塊和依賴注入，感興趣的小伙伴們可以參考一下

廢話不多說(shuō)，進(jìn)入正題...

首先我們看下文件結(jié)構(gòu)：

Angular-ocLazyLoad           --- demo文件夾
  Scripts               --- 框架及插件文件夾
    angular-1.4.7          --- angular 不解釋
    angular-ui-router        --- uirouter 不解釋
    oclazyload           --- ocLazyload 不解釋
    bootstrap            --- bootstrap 不解釋
    angular-tree-control-master   --- angular-tree-control-master 不解釋
    ng-table            --- ng-table 不解釋
    angular-bootstrap        --- angular-bootstrap 不解釋
  js                 --- js文件夾 針對(duì)demo寫的js文件
    controllers           --- 頁(yè)面控制器文件夾
      angular-tree-control.js   --- angular-tree-control控制器代碼
      default.js         --- default控制器代碼
      ng-table.js         --- ng-table控制器代碼
    app.config.js          --- 模塊注冊(cè)及配置代碼
    oclazyload.config.js      --- 加載模塊配置代碼
    route.config.js         --- 路由配置及加載代碼
  views                --- html頁(yè)面文件夾
    angular-tree-control.html    --- angular-tree-control插件的效果頁(yè)面
    default.html          --- default頁(yè)面
    ng-table.html          --- ng-table插件效果頁(yè)面
    ui-bootstrap.html        --- uibootstrap插件效果頁(yè)面
  index.html             --- 主頁(yè)面

注意：這個(gè)demo沒(méi)做嵌套路由，只是簡(jiǎn)單實(shí)現(xiàn)單視圖的路由以展示效果。

我們來(lái)看主頁(yè)面的代碼：

<html>
<head>
  <meta charset="utf-8" />
  <title></title>
  <link rel="stylesheet" href="Scripts/bootstrap/dist/css/bootstrap.min.css" />
  <script src="Scripts/angular-1.4.7/angular.js"></script>
  <script src="Scripts/angular-ui-router/release/angular-ui-router.min.js"></script>
  <script src="Scripts/oclazyload/dist/ocLazyLoad.min.js"></script>
  <script src="js/app.config.js"></script>
  <script src="js/oclazyload.config.js"></script>
  <script src="js/route.config.js"></script>
</head>
<body>
<div ng-app="templateApp">
  <div>
    <a href="#/default">主頁(yè)</a>
    <a href="#/uibootstrap" >ui-bootstrap</a>
    <a href="#/ngtable">ng-table</a>
    <a href="#/ngtree">angular-tree-control</a>
  </div>
  <div ui-view></div>
</div>
</body>
</html>

在這個(gè)頁(yè)面，我們只加載了bootstrap的css、angular的js、ui-router的js、ocLazyLoad的js，以及3個(gè)配置的js文件。
再看看四個(gè)頁(yè)面的html代碼：

angular-tree-control效果頁(yè)面

<treecontrol tree-model="ngtree.treeData" class="tree-classic ng-cloak" options="ngtree.treeOptions">
  {{node.title}}
</treecontrol>

頁(yè)面上有個(gè)使用該插件對(duì)應(yīng)的指令。

default頁(yè)面

<div class="ng-cloak">
  {{default.value}}
</div>

這里我們只是用來(lái)證明加載并正確執(zhí)行default.js。

ng-table效果頁(yè)面

<div class="ng-cloak">
  <div class="p-h-md p-v bg-white box-shadow pos-rlt">
    <h3 class="no-margin">ng-table</h3>
  </div>
  <button ng-click="ngtable.tableParams.sorting({})" class="btn btn-default pull-right">Clear sorting</button>
  <p>
    <strong>Sorting:</strong> {{ngtable.tableParams.sorting()|json}}
  </p>
  <table ng-table="ngtable.tableParams" class="table table-bordered table-striped">
    <tr ng-repeat="user in $data">
      <td data-title="'Name'" sortable="'name'">
        {{user.name}}
      </td>
      <td data-title="'Age'" sortable="'age'">
        {{user.age}}
      </td>
    </tr>
  </table>
</div>

這里寫了些簡(jiǎn)單的ng-table效果。

ui-bootstrap效果頁(yè)面

<span uib-dropdown class="ng-cloak">
  <a href id="simple-dropdown" uib-dropdown-toggle>
    下拉框觸發(fā)
  </a>
  <ul class="uib-dropdown-menu dropdown-menu" aria-labelledby="simple-dropdown">
    下拉框內(nèi)容.這里寫個(gè)效果證明實(shí)現(xiàn)動(dòng)態(tài)加載即可
  </ul>
</span>

這里僅寫了個(gè)下拉框效果，證明正確加載并使用該插件。
好了，看完了html，我們看下加載配置和路由配置：

"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.register;
          tempApp.filter = $filterProvider.register;
          tempApp.factory = $provide.factory;
          tempApp.service =$provide.service;
          tempApp.constant = $provide.constant;
        }]);

以上代碼對(duì)模塊的注冊(cè)，僅僅依賴了ui.router和oc.LazyLoad。配置也只是簡(jiǎn)單配置了模塊，以便在后面的js能識(shí)別到tempApp上的方法。
然后我們?cè)倏纯磑cLazyLoad加載模塊的配置：

"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","$locationProvider",routeFn]);
function routeFn($stateProvider,$urlRouterProvider,$locationProvider){
  $urlRouterProvider.otherwise("/default");
  $stateProvider
  .state("default",{
    url:"/default",
    views:{
      "":{
        templateUrl:"views/default.html",
        controller:"defaultCtrl",
        controllerAs:"default"
      }
    },
    resolve:{
      deps:["$ocLazyLoad",function($ocLazyLoad){
        return $ocLazyLoad.load("js/controllers/default.js");
      }]
    }
  })
  .state("uibootstrap",{
    url:"/uibootstrap",
    views:{
      "":{
        templateUrl:"views/ui-bootstrap.html"
      }
    },
    resolve:{
      deps:["$ocLazyLoad",function($ocLazyLoad){
        return $ocLazyLoad.load("ui.bootstrap");
      }]
    }
  })
  .state("ngtable",{
    url:"/ngtable",
    views:{
      "":{
        templateUrl:"views/ng-table.html",
        controller:"ngTableCtrl",
        controllerAs:"ngtable"
      }
    },
    resolve:{
      deps:["$ocLazyLoad",function($ocLazyLoad){
        return $ocLazyLoad.load("ngTable").then(
          function(){
            return $ocLazyLoad.load("js/controllers/ng-table.js");
          }
        );
      }]
    }
  })
  .state("ngtree",{
    url:"/ngtree",
    views:{
      "":{
        templateUrl:"views/angular-tree-control.html",
        controller:"ngTreeCtrl",
        controllerAs:"ngtree"
      }
    },
    resolve:{
      deps:["$ocLazyLoad",function($ocLazyLoad){
        return $ocLazyLoad.load("treeControl").then(
          function(){
            return $ocLazyLoad.load("js/controllers/angular-tree-control.js");
          }
        );
      }]
    }
  })
};

ui-bootstrap的下拉框簡(jiǎn)單的實(shí)現(xiàn)不需要控制器，那么我們就只看看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){
  var vm = this;
  //數(shù)據(jù)
  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 }];
  vm.tableParams = new NgTableParams(  // 合并默認(rèn)的配置和url參數(shù)
    angular.extend({
      page: 1,      // 第一頁(yè)
      count: 10,     // 每頁(yè)的數(shù)據(jù)量
      sorting: {
        name: 'asc'   // 默認(rèn)排序
      }
    },
    $location.search())
    ,{
      total: data.length, // 數(shù)據(jù)總數(shù)
      getData: function ($defer, params) {
        $location.search(params.url()); // 將參數(shù)放到url上，實(shí)現(xiàn)刷新頁(yè)面不會(huì)跳回第一頁(yè)和默認(rèn)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(){
  var vm = this;
  //樹數(shù)據(jù)
  vm.treeData = [
        {
          id:"1",
          title:"標(biāo)簽1",
          childList:[
            {
              id:"1-1",
              title:"子級(jí)1",
              childList:[
                {
                  id:"1-1-1",
                  title:"再子級(jí)1",
                  childList:[]
                }
              ]
            },
            {
              id:"1-2",
              title:"子級(jí)2",
              childList:[
                {
                  id:"1-2-1",
                  title:"再子級(jí)2",
                  childList:[
                    {
                      id:"1-2-1-1",
                      title:"再再子級(jí)1",
                      childList:[]
                    }
                  ]
                }
              ]
            },
            {
              id:"1-3",
              title:"子級(jí)3",
              childList:[]
            }
          ]
        },
        {
          id:"2",
          title:"標(biāo)簽2",
          childList:[
            {
              id:"2-1",
              title:"子級(jí)1",
              childList:[]
            },
            {
              id:"2-2",
              title:"子級(jí)2",
              childList:[]
            },
            {
              id:"2-3",
              title:"子級(jí)3",
              childList:[]
            }
          ]}
        ,
        {
          id:"3",
          title:"標(biāo)簽3",
          childList:[
            {
              id:"3-1",
              title:"子級(jí)1",
              childList:[]
            },
            {
              id:"3-2",
              title:"子級(jí)2",
              childList:[]
            },
            {
              id:"3-3",
              title:"子級(jí)3",
              childList:[]
            }
          ]
        }
      ];
  //樹配置
  vm.treeOptions = {
   nodeChildren:"childList",
    dirSelectable:false
  };
};
})();

讓我們忽略default.js吧，畢竟里面只有個(gè)"Hello Wrold"。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助。
