最近項目比較忙額，白天要上班，晚上回來還需要做Angular知識點的ppt給同事，畢竟年底要辭職了，項目的後續開發還是需要有人接手的，所以就占用了晚上學習的時間。本來一直不打算寫這些第三方插件的學習筆記，不過覺得按需載入模塊並且成功使用這個確實是個好處，還是記錄下來吧。基於本獸沒怎麼深入的使用requireJs，所以本獸不知道這個和requireJs有什麼區別，也不能清晰的說明這到底算不算Angular的按需載入。
為了實現這篇學習筆記知識點的效果，我們需要用到：
angular:https://github.com/angular/angular.js
ui-router:https://github.com/angular-ui/ui-router
ocLazyLoad:https://github.com/ocombe/ocLazyLoad
廢話不多說，進入正題...
首先我們看下文件結構：
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demo寫的js文件
controllers --- 頁面控制器文件夾
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 --- 模塊註冊及配置代碼
oclazyload.config.js --- 載入模塊配置代碼
route.config.js --- 路由配置及載入代碼
views --- html頁面文件夾
angular-tree-control.html --- angular-tree-control插件的效果頁面
default.html --- default頁面
ng-table.html --- ng-table插件效果頁面
ui-bootstrap.html --- uibootstrap插件效果頁面
index.html --- 主頁面
註意：這個demo沒做嵌套路由，只是簡單實現單視圖的路由以展示效果。
我們來看主頁面的代碼：
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<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</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>
在這個頁面，我們只載入了bootstrap的css、angular的js、ui-router的js、ocLazyLoad的js，以及3個配置的js文件。
再看看四個頁面的html代碼：
angular-tree-control效果頁面
<treecontrol tree-model="ngtree.treeData" class="tree-classic ng-cloak" options="ngtree.treeOptions">
{{node.title}}
</treecontrol>
頁面上有個使用該插件對應的指令。
default頁面
<div class="ng-cloak">
{{default.value}}
</div>
這裡我們只是用來證明載入並正確執行default.js。
ng-table效果頁面
<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 $data">
<td data-title="'Name'" sortable="'name'">
{{user.name}}
</td>
<td data-title="'Age'" sortable="'age'">
{{user.age}}
</td>
</tr>
</table>
</div>
這裡寫了些簡單的ng-table效果。
ui-bootstrap效果頁面
<span uib-dropdown class="ng-cloak">
<a href id="simple-dropdown" uib-dropdown-toggle>
下拉框觸發
</a>
<ul class="uib-dropdown-menu dropdown-menu" aria-labelledby="simple-dropdown">
下拉框內容.這裡寫個效果證明實現動態載入即可
</ul>
</span>
這裡僅寫了個下拉框效果，證明正確載入並使用該插件。
好了，看完了html，我們看下載入配置和路由配置：
"use strict"
var tempApp = angular.module("templateApp",["ui.router","oc.lazyLoad"])
.config(["$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 = $provide.constant;
}]);
以上代碼對模塊的註冊，僅僅依賴了ui.router和oc.LazyLoad。配置也只是簡單配置了模塊，以便在後面的js能識別到tempApp上的方法。
然後我們再看看ocLazyLoad載入模塊的配置：
"use strict"
tempApp
.constant("Modules_Config",[
{
name:"ngTable",
module:true,
files:[
"Scripts/ng-table/dist/ng-table.min.css",
"Scripts/ng-table/dist/ng-table.min.js"
]
},
{
name:"ui.bootstrap",
module:true,
files:[
"Scripts/angular-bootstrap/ui-bootstrap-tpls-0.14.3.min.js"
]
},
{
name:"treeControl",
module:true,
files:[
"Scripts/angular-tree-control-master/css/tree-control.css",
"Scripts/angular-tree-control-master/css/tree-control-attribute.css",
"Scripts/angular-tree-control-master/angular-tree-control.js"
]
}
])
.config(["$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","$urlRouterProvider",routeFn]);
function routeFn($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 $ocLazyLoad.load("js/controllers/angular-tree-control.js");
}
);
}]
}
})
};
ui-bootstrap的下拉框簡單的實現不需要控制器，那麼我們就只看看ng-table和angular-tree-control的控制器js吧：
ng-table.js
(function(){
"use strict"
tempApp
.controller("ngTableCtrl",["$location","NgTableParams","$filter",ngTableCtrlFn]);
function ngTableCtrlFn($location,NgTableParams,$filter){
var vm = this;
//數據
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( // 合併預設的配置和url參數
angular.extend({
page: 1, // 第一頁
count: 10, // 每頁的數據量
sorting: {
name: 'asc' // 預設排序
}
},
$location.search())
,{
total: data.length, // 數據總數
getData: function ($defer, params) {
$location.search(params.url()); // 將參數放到url上，實現刷新頁面不會跳回第一頁和預設配置
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;
//樹數據
vm.treeData = [
{
id:"1",
title:"標簽1",
childList:[
{
id:"1-1",
title:"子級1",
childList:[
{
id:"1-1-1",
title:"再子級1",
childList:[]
}
]
},
{
id:"1-2",
title:"子級2",
childList:[
{
id:"1-2-1",
title:"再子級2",
childList:[
{
id:"1-2-1-1",
title:"再再子級1",
childList:[]
}
]
}
]
},
{
id:"1-3",
title:"子級3",
childList:[]
}
]
},
{
id:"2",
title:"標簽2",
childList:[
{
id:"2-1",
title:"子級1",
childList:[]
},
{
id:"2-2",
title:"子級2",
childList:[]
},
{
id:"2-3",
title:"子級3",
childList:[]
}
]}
,
{
id:"3",
title:"標簽3",
childList:[
{
id:"3-1",
title:"子級1",
childList:[]
},
{
id:"3-2",
title:"子級2",
childList:[]
},
{
id:"3-3",
title:"子級3",
childList:[]
}
]
}
];
//樹配置
vm.treeOptions = {
nodeChildren:"childList",
dirSelectable:false
};
};
})();
讓我們忽略default.js吧，畢竟裡面只有個"Hello Wrold"。
