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
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：
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
{{node.title}}
页面上有个使用该插件对应的指令。
default页面
{{default.value}}
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
ng-table
Sorting: {{ngtable.tableParams.sorting()|json}}
{{user.name}} {{user.age}}
这里写了些简单的ng-table效果。
ui-bootstrap效果页面
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 = $provide.constant;
}]);
以上代码对模块的注册，仅仅依赖了ui.router和oc.LazyLoad。配置也只是简单配置了模块，以便在后面的js能识别到tempApp上的方法。
然后我们再看看ocLazyLoad加载模块的配置：
"use strict"
tempApp
.constant("Modules_Config",[
{
name:"ngTable",
module:true,
files:[
"Scripts/ng-table/dist/ng-table.min.css",
"Scripts/ng-table/dist/ng-table.min.js"
]
},
{
name:"ui.bootstrap",
module:true,
files:[
"Scripts/angular-bootstrap/ui-bootstrap-tpls-0.14.3.min.js"
]
},
{
name:"treeControl",
module:true,
files:[
"Scripts/angular-tree-control-master/css/tree-control.css",
"Scripts/angular-tree-control-master/css/tree-control-attribute.css",
"Scripts/angular-tree-control-master/angular-tree-control.js"
]
}
])
.config(["$ocLazyLoadProvider","Modules_Config",routeFn]);
function routeFn($ocLazyLoadProvider,Modules_Config){
$ocLazyLoadProvider.config({
debug:false,
events:false,
modules:Modules_Config
});
};
路由的配置：
"use strict"
tempApp.config(["$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 $ocLazyLoad.load("js/controllers/angular-tree-control.js");
}
);
}]
}
})
};
ui-bootstrap的下拉框简单的实现不需要控制器，那么我们就只看看ng-table和angular-tree-control的控制器js吧：
ng-table.js
(function(){
"use strict"
tempApp
.controller("ngTableCtrl",["$location","NgTableParams","$filter",ngTableCtrlFn]);
function ngTableCtrlFn($location,NgTableParams,$filter){
var vm = this;
//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
};
};
})();
让我们忽略default.js吧，毕竟里面只有个"Hello Wrold"。
以上就是本文的全部内容，希望对大家的学习有所帮助。
