Tanpa berlengah lagi, mari kita ke intinya...

Mula-mula mari kita lihat struktur fail:

  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

      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

Nota: Demo ini tidak melaksanakan penghalaan bersarang, tetapi hanya melaksanakan penghalaan pandangan tunggal untuk menunjukkan kesannya.

Mari lihat kod halaman utama:

<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">主页</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>

Pada halaman ini, kami hanya memuatkan css bootstrap, js angular, js ui-router, js ocLazyLoad dan 3 fail js yang dikonfigurasikan.
Lihat sekali lagi kod html empat halaman:

halaman kesan kawalan pokok sudut

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

Terdapat arahan untuk menggunakan pemalam pada halaman.

halaman lalai

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

Di sini kami hanya menggunakannya untuk membuktikan bahawa default.js dimuatkan dan dilaksanakan dengan betul.

halaman kesan ng-jadual

<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>

Berikut ialah beberapa kesan ng-table yang ringkas.

halaman kesan ui-bootstrap

<span uib-dropdown class="ng-cloak">
  <a href id="simple-dropdown" uib-dropdown-toggle>
    下拉框触发
  </a>
  <ul class="uib-dropdown-menu dropdown-menu" aria-labelledby="simple-dropdown">
    下拉框内容.这里写个效果证明实现动态加载即可
  </ul>
</span>

Hanya kesan kotak lungsur yang ditulis di sini untuk membuktikan bahawa pemalam dimuatkan dan digunakan dengan betul.
Okay, selepas membaca html, mari kita lihat konfigurasi pemuatan dan konfigurasi penghalaan:

"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;
        }]);

Kod di atas hanya bergantung pada ui.router dan oc.LazyLoad untuk mendaftarkan modul. Konfigurasi hanyalah konfigurasi ringkas modul supaya js seterusnya dapat mengenali kaedah pada tempApp.
Kemudian mari kita lihat konfigurasi modul pemuatan ocLazyLoad:

"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
  });
};

Konfigurasi penghalaan:

"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");
          }
        );
      }]
    }
  })
};

Pelaksanaan mudah kotak lungsur ui-bootstrap tidak memerlukan pengawal, jadi mari kita lihat js pengawal ng-table dan angular-tree-control:

ng-table.js

(function(){
"use strict"
tempApp
.controller("ngTableCtrl",["$location","NgTableParams","$filter",ngTableCtrlFn]);
function ngTableCtrlFn($location,NgTableParams,$filter){
  var vm = this;
  //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 }];
  vm.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 &#63;
            $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;
  //树数据
  vm.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
  vm.treeOptions = {
   nodeChildren:"childList",
    dirSelectable:false
  };
};
})();

Mari kita abaikan default.js, lagipun hanya terdapat "Hello Wrold" di dalamnya.
