首先，我們來看一下工程結構目錄：
我們可以看到scripts中分列了一下幾個文件夾：controllers、services、directives、filters、vendor，以及兩個文件app.js和main.js。
controllers裏面主要就是控制器
services裏面是服務，爲控制器提供數據服務支持，與後臺交互的代碼就在其中
directives是指令，用於生成自定義標籤的html模板
filters是過濾器，用於處理顯示數據的形式
vendor文件夾中存放的是引用的第三方js插件
跟scripts同級的是styles和views文件夾，styles存放css樣式文件，view存放html文件。
我們先來看一下index.html中的主要代碼：
<!DOCTYPE html> <html> <!-- Do not add ng-app here as we bootstrap AngularJS manually--> <head> <title>My AngularJS App</title> <meta charset="utf-8" /> <link rel="stylesheet" type="text/css" href="styles/bootstrap.min.css"> <link rel="stylesheet" type="text/css" href="styles/ng-grid.css" /> <link rel="stylesheet" type="text/css" href="styles/main.css"> </head> <body class="home-page row-fluid"> <nav class="navbar navbar-default"> …… </nav> <div class="col-lg-10 col-md-12 col-sm-12 col-sm-12 col-lg-offset-1"> <div ng-view></div> </div> <div class="row-fluid"> </div> <script data-main="scripts/main" src="scripts/vendor/require.js"></script> </body> </html>
我們可以看到導入的js只有一個require.js，但是這個script中有個這樣的屬性
data-main="scripts/main"
這個屬性就將主js指向了scripts/main.js。
下面來看main.js，其中，分爲了兩塊，第一塊是對第三方的引用和依賴配置：
// the app/scripts/main.js file, which defines our RequireJS config
require.config({
paths:{
angular:'vendor/angular.min',
jquery:'vendor/jquery',
bootstrap:'vendor/bootstrap.min',
domReady:'vendor/domReady',
ngGrid:'vendor/ng-grid.debug'
},
shim:{
angular:{
deps:[ 'jquery'],
exports:'angular'
},
ngGrid:{
deps:[ 'jquery']
},
bootstrap:{
deps:[ 'jquery']
}
}
});第二塊就是主要的引用和route信息了：
require([
'angular',
'app',
'domReady',
'bootstrap',
'services/userService',
'controllers/rootController',
'directives/ngbkFocus',
'controllers/user/listController',
'controllers/user/editController',
'controllers/user/newController',
'ngGrid'
// Any individual controller, service, directive or filter file
// that you add will need to be pulled in here.
],
function (angular, app, domReady) {
'use strict';
app.config(['$routeProvider',
function ($routeProvider) {
$routeProvider.when('/', {
templateUrl:'views/user/list.html',//當跳轉到該路徑時，將此html嵌入到ng-view屬性的dom中
controller:'ListCtrl'//當前templateUrl的controller爲ListCtrl
})
.when('/edit/:name/:allowance', {
templateUrl:'views/user/form.html',
controller:'EditCtrl'
})
.when('/new', {
templateUrl:'views/user/form.html',
controller:'NewCtrl'
})
.when('/root', {
templateUrl:'views/root.html',
controller:'RootCtrl'
});
}
]);
domReady(function () {
angular.bootstrap(document, ['MyApp']);//app名爲MyApp
// The following is required if you want AngularJS Scenario tests to work
$('html').addClass('ng-app: MyApp');//給html添加ng-app屬性
});
}
);以list的route爲示例，我們來講解controller,先看一張list效果圖（此處我們引用了ng-grid插件）：
我們來看引入的controllers/user/listController：
define(['controllers/controllers', 'services/userService'],
function (controllers) {
controllers.controller('ListCtrl', ['$scope', '$http', '$location', 'UserService',//此處數組中的參數依次對應下面回調方法中的參數
function ($scope, $http, $location, UserService) {
$scope.mySelections = [];
$scope.filterOptions = {
filterText:"",
useExternalFilter:true
};
$scope.totalServerItems = 0;
$scope.pagingOptions = {
pageSizes:[250, 500, 1000],
pageSize:250,
currentPage:1
};
$scope.setPagingData = function (data, page, pageSize) {
var pagedData = data.slice((page - 1) * pageSize, page * pageSize);
$scope.myData = pagedData;
$scope.totalServerItems = data.length;
if (!$scope.$$phase) {
$scope.$apply();
}
};
$scope.getPagedDataAsync = function (pageSize, page, searchText) {
setTimeout(function () {
var data;
if (searchText) {
var ft = searchText.toLowerCase();
UserService.getServerData(function (largeLoad) {
data = largeLoad.filter(function (item) {
return JSON.stringify(item).toLowerCase().indexOf(ft) != -1;
});
$scope.setPagingData(data, page, pageSize);
});
} else {
UserService.getServerData(function (largeLoad) {
$scope.setPagingData(largeLoad, page, pageSize);
});
}
}, 100);
};
$scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage);
$scope.$watch('pagingOptions', function (newVal, oldVal) {
if (newVal !== oldVal && newVal.currentPage !== oldVal.currentPage) {
$scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.filterOptions.filterText);
}
}, true);
$scope.$watch('filterOptions', function (newVal, oldVal) {
if (newVal !== oldVal) {
$scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.filterOptions.filterText);
}
}, true);
$scope.clickme = function (v) {
$location.path('/edit/' + v.name + "/" + v.allowance);
}
$scope.gridOptions = {
data:'myData',
enablePaging:true,
showFooter:true,
totalServerItems:'totalServerItems',
pagingOptions:$scope.pagingOptions,
filterOptions:$scope.filterOptions,
selectedItems:$scope.mySelections,
showSelectionCheckbox:true,
columnDefs:[
{ field:"name", pinned:true }
,
{ field:"allowance", cellTemplate:'<div class="ngCellText" ng-class="col.colIndex()"><span ng-cell-text>{{COL_FIELD | currency}}</span></div>'}
,
{ field:"entity", pinned:true, cellTemplate:'<div class="ngCellText" ng-class="col.colIndex()"><span ng-cell-text>{{$parent.row.entity | myfilter}}</span></div>' }
,
{ field:"name", width:100, cellTemplate:'<button class="btn-xs table-btn" ng-click="clickme($parent.row.entity)"><span class="glyphicon glyphicon-search" aria-hidden="true"></span></button>'}
]/*,
multiSelect:false*/
};
}]);
});其中定義了該controller名爲ListCtrl，$scope爲局部變量，其中定義的數據與方法可在當前Ctrl作用域內生效，我們來看一下生效的list.html是怎麼樣的
<div class="gridStyle" ng-grid="gridOptions"></div>
就是這麼一句話，定義了grid的div，其餘的都交給了controller和ng-grid插件
listController中引用了services/userService，service層用來與後臺交互，管理數據：
define(['services/services'],
function (services) {
services.factory('UserService', ['$http',
function ($http) {
return {
getData:function () {
return [
{ name:"Moroni", age:50, birthday:"Oct 28, 1970", salary:"60,000" },
{ name:"Tiancum", age:43, birthday:"Feb 12, 1985", salary:"70,000" },
{ name:"Jacob", age:27, birthday:"Aug 23, 1983", salary:"50,000" },
{ name:"Nephi", age:29, birthday:"May 31, 2010", salary:"40,000" },
{ name:"Enos", age:34, birthday:"Aug 3, 2008", salary:"30,000" },
{ name:"Moroni", age:50, birthday:"Oct 28, 1970", salary:"60,000" },
{ name:"Tiancum", age:43, birthday:"Feb 12, 1985", salary:"70,000" },
{ name:"Jacob", age:27, birthday:"Aug 23, 1983", salary:"40,000" },
{ name:"Nephi", age:29, birthday:"May 31, 2010", salary:"50,000" },
{ name:"Enos", age:34, birthday:"Aug 3, 2008", salary:"30,000" },
{ name:"Moroni", age:50, birthday:"Oct 28, 1970", salary:"60,000" },
{ name:"Tiancum", age:43, birthday:"Feb 12, 1985", salary:"70,000" },
{ name:"Jacob", age:27, birthday:"Aug 23, 1983", salary:"40,000" },
{ name:"Nephi", age:29, birthday:"May 31, 2010", salary:"50,000" },
{ name:"Enos", age:34, birthday:"Aug 3, 2008", salary:"30,000" }
];
},
getOptions:function () {
return {
data:'myData',
enablePinning:true,
columnDefs:[
{ field:"name", width:120, pinned:true },
{ field:"age", width:120 },
{ field:"birthday", width:120 },
{ field:"salary", width:120 }
]
}
},
getServerData:function (success) {
$http.get('jsonFiles/largeLoad.json').success(success);
},
saveData:function (data, success) {
$http.post('/users/save', data).success(success);
}
};
}]);
});其中引用的$http是用來管理ajax的對象，類似的對象還有$location，用來管理url地址，類似的對象還有很多，詳細可以參見官方API文檔。
至此，一個前端MVC框架基本構建完成，在之後的一篇中我們來着重介紹下還沒講過的filters和directives。
