本文主要包含AngularJs动态加载模块和依赖注入详解等相关知识,野兽'' 希望在学习及工作中可以帮助到您
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
</div>
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：
<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>
</div>
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
<treecontrol tree-model="ngtree.treeData" class="tree-classic ng-cloak" options="ngtree.treeOptions">
{{node.title}}
</treecontrol>
</div>
页面上有个使用该插件对应的指令。
default页面
<div class="ng-cloak">
{{default.value}}
</div>
</div>
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
<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 $data">
<td data-title="'Name'" sortable="'name'">
{{user.name}}
</td>
<td data-title="'Age'" sortable="'age'">
{{user.age}}
</td>
</tr>
</table>
</div>
</div>
这里写了些简单的ng-table效果。
ui-bootstrap效果页面
<span uib-dropdown class="ng-cloak">
<a href id="simple-dropdown" uib-dropdown-toggle>
下拉框触发
</a>
<ul class="uib-dropdown-menu dropdown-menu" aria-labelledby="simple-dropdown">
下拉框内容.这里写个效果证明实现动态加载即可
</ul>
</span>
</div>
这里仅写了个下拉框效果，证明正确加载并使用该插件。
好了，看完了html，我们看下加载配置和路由配置：
"use strict"
var tempApp = angular.module("templateApp",["ui.router","oc.lazyLoad"])
.config(["$provide","$compileProvider","$controllerProvider","$filterProvider",
function($provide,$compileProvider,$controllerProvider,$filterProvider){
tempApp.controller = $controllerProvider.register;
tempApp.directive = $compileProvider.register;
tempApp.filter = $filterProvider.register;
tempApp.factory = $provide.factory;
tempApp.service =$provide.service;
tempApp.constant = $provide.constant;
}]);
</div>
以上代码对模块的注册，仅仅依赖了ui.router和oc.LazyLoad。配置也只是简单配置了模块，以便在后面的js能识别到tempApp上的方法。
然后我们再看看ocLazyLoad加载模块的配置：
"use strict"
tempApp
.constant("Modules_Config",[
{
name:"ngTable",
module:true,
files:[
"Scripts/ng-table/dist/ng-table.min.css",
"Scripts/ng-table/dist/ng-table.min.js"
]
},
{
name:"ui.bootstrap",
module:true,
files:[
"Scripts/angular-bootstrap/ui-bootstrap-tpls-0.14.3.min.js"
]
},
{
name:"treeControl",
module:true,
files:[
"Scripts/angular-tree-control-master/css/tree-control.css",
"Scripts/angular-tree-control-master/css/tree-control-attribute.css",
"Scripts/angular-tree-control-master/angular-tree-control.js"
]
}
])
.config(["$ocLazyLoadProvider","Modules_Config",routeFn]);
function routeFn($ocLazyLoadProvider,Modules_Config){
$ocLazyLoadProvider.config({
debug:false,
events:false,
modules:Modules_Config
});
};
</div>
路由的配置：
"use strict"
tempApp.config(["$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",{
