Web Front-endJS TutorialAngularJs dynamically loaded modules and dependency injection detailed explanation_AngularJSAngularJs dynamically loaded modules and dependency injection detailed explanation_AngularJS
Without further ado, let’s get to the point...
First let’s take a look at the file structure:
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
Note: This demo does not implement nested routing, but simply implements single-view routing to show the effect.
Let’s look at the code of the main page:
<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>
On this page, we only loaded bootstrap’s css, angular’s js, ui-router’s js, ocLazyLoad’s js, and 3 configured js files.
Take another look at the html code of the four pages:
angular-tree-control effect page
<treecontrol tree-model="ngtree.treeData" class="tree-classic ng-cloak" options="ngtree.treeOptions">
{{node.title}}
</treecontrol>
There are instructions for using the plug-in on the page.
default page
<div class="ng-cloak">
{{default.value}}
</div>
Here we just use it to prove that default.js is loaded and executed correctly.
ng-table effect page
<div class="ng-cloak">
<div class="p-h-md p-v bg-white box-shadow pos-rlt">
<h3 id="ng-table">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 $data">
<td data-title="'Name'" sortable="'name'">
{{user.name}}
</td>
<td data-title="'Age'" sortable="'age'">
{{user.age}}
</td>
</tr>
</table>
</div>
Here are some simple ng-table effects.
ui-bootstrap effect page
<span uib-dropdown class="ng-cloak">
<a href id="simple-dropdown" uib-dropdown-toggle>
下拉框触发
</a>
<ul class="uib-dropdown-menu dropdown-menu" aria-labelledby="simple-dropdown">
下拉框内容.这里写个效果证明实现动态加载即可
</ul>
</span>
Only a drop-down box effect is written here to prove that the plug-in is loaded and used correctly.
Okay, after reading the html, let’s take a look at the loading configuration and routing configuration:
"use strict"
var tempApp = angular.module("templateApp",["ui.router","oc.lazyLoad"])
.config(["$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 = $provide.constant;
}]);
The above code only relies on ui.router and oc.LazyLoad to register the module. The configuration is just a simple configuration of the module so that the subsequent js can recognize the methods on tempApp.
Then let’s take a look at the configuration of the ocLazyLoad loading module:
"use strict"
tempApp
.constant("Modules_Config",[
{
name:"ngTable",
module:true,
files:[
"Scripts/ng-table/dist/ng-table.min.css",
"Scripts/ng-table/dist/ng-table.min.js"
]
},
{
name:"ui.bootstrap",
module:true,
files:[
"Scripts/angular-bootstrap/ui-bootstrap-tpls-0.14.3.min.js"
]
},
{
name:"treeControl",
module:true,
files:[
"Scripts/angular-tree-control-master/css/tree-control.css",
"Scripts/angular-tree-control-master/css/tree-control-attribute.css",
"Scripts/angular-tree-control-master/angular-tree-control.js"
]
}
])
.config(["$ocLazyLoadProvider","Modules_Config",routeFn]);
function routeFn($ocLazyLoadProvider,Modules_Config){
$ocLazyLoadProvider.config({
debug:false,
events:false,
modules:Modules_Config
});
};
Routing configuration:
"use strict"
tempApp.config(["$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 $ocLazyLoad.load("js/controllers/angular-tree-control.js");
}
);
}]
}
})
};
The simple implementation of ui-bootstrap's drop-down box does not require a controller, so let's just look at the controller js of ng-table and angular-tree-control:
ng-table.js
(function(){
"use strict"
tempApp
.controller("ngTableCtrl",["$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 ?
$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
};
};
})();
Let us ignore default.js, after all there is only "Hello Wrold" in it.
The above is the entire content of this article, I hope it will be helpful to everyone’s study.
From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AMThe shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
