Demo1:简介
ng-app ng-model
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app=""> <p>名字:<input type="text" ng-model="name"></p> <h1>Hello {{name}}</h1> </div> </body> </html>
ng-bind ng-init
<!-- ng-init 指令初始化 AngularJS 应用程序变量 ng-bind 指令把应用程序变量 name 绑定到某个段落的 innerHTML div要包含住ng-app,否则ng元素失效 --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="" ng-init="firstName=\'John\'"> <p>姓名为:<span ng-bind="firstName"></span></p> </div> </body> </html>
Module Controller 用汉字才能对齐,用英文就丑了
<!-- AngularJS 模块(Module) 定义了 AngularJS 应用。 AngularJS 控制器(Controller) 用于控制 AngularJS 应用。 ng-app指令定义了应用, ng-controller 定义了控制器。 --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <p>尝试修改以下表单。</p> <div ng-app="myApp" ng-controller="myCtrl"> 姓: <input type="text" ng-model="lastName"><br> 名: <input type="text" ng-model="firstName"><br><br> name: {{firstName +" "+ lastName}} </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.firstName = \'John\'; $scope.lastName = \'Doe\'; }) </script> </body> </html>
-------------------------------------------------------------------------------------------
HTML 属性应当按照以下给出的顺序依次排列,确保代码的易读性。
- class
- id, name
- data-*
- src, for, type, href
- title, alt
- aria-*, role

Demo2:指令
HTML控制器input/select/textarea
ng-repeat
<!-- ng-repeat 指令会重复一个 HTML 元素 -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>
<div data-ng-app="" data-ng-init="names=[\'tab\', \'ctrl\', \'shift\']">
<ul>
<li data-ng-repeat="x in names">
{{x}}
</li>
</ul>
</div>
</body>
</html>
directive自定义指令
<!-- angular.module小写 restrict 值可以是以下几种: E 只限元素名使用 A 只限属性使用 C 只限类名使用 M 只限注释使用 restrict写在template同样的位置 --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body ng-app="myApp"> <miao-directive></miao-directive> <script> var myApp = angular.module(\'myApp\', []); myApp.directive(\'miaoDirective\', function() { return {template: \'<h1>自定义指令!</h1>\'}; }); </script> </body> </html>
Demo3:模型
ng-model 指令用于绑定应用程序数据到 HTML 控制器(input, select, textarea)的值。
ng-model
<!-- 引用controller内容就用ng-model --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> 名字:<input type="text" ng-model="name"> </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.name = \'Miaomiao Tab\'; }); </script> </body> </html>
.
<!-- angular写成了angula --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app=\'myApp\' ng-controller=\'myCtrl\'> 名字:<input type="text" ng-model="name"> <h1>你输入了{{name}}</h1> </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.name = \'Miaomiao Tab\'; }); </script> </body> </html>
error email ng-show
<!-- div : form text is required in span to show--> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <form ng-app="" name="myForm"> Email: <input type="email" name="myAddress" ng-model="text"> <span ng-show="myForm.myAddress.$error.email">email error</span> <p>在输入框中输入你的邮箱地址,如果不是一个合法的邮箱地址,会弹出提示信息。</p> </form> </body> </html>
valid dirty touched
<!-- {{}} myForm.myAddress.$valid not .email added--> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <form name="myForm" ng-app=""> Email: <input type="email" name="myAddress" ng-model="text"> <p>编辑邮箱地址,查看状态的改变。</p> <h1>状态</h1> <p>Valid: {{myForm.myAddress.$valid}}(如果输入的值是合法的则为 true)。</p> <p>Dirty: {{myForm.myAddress.$dirty}}(如果值改变则为true )。</p> <p>Touched: {{myForm.myAddress.$touched}}(如果触屏点击的则为 true)。</p> </form> </body> </html>
bgcolor
<!-- <style type="text/css"> ng-model="myText" input.ng-invalid not input .ng-invalid --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> <style> input.ng-invalid{ background-color: lightblue } </style> </head> <body> <form name="myForm" ng-app=""> <span>输入你的名字:</span> <input name="myName" ng-model="myText" required> </form> <p>编辑文本域,不同状态背景颜色会发送变化。</p> <p>文本域添加了 required 属性,该值是必须的,如果为空则是不合法的。</p> </body> </html>
Demo4:控制域
scope作用域:HTML视图与javascript控制器之间的纽带
.
<!-- app.controller(\'myCtrl\', function($scope) --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> <h1>{{carTab}}</h1> </div> <p>控制器中创建一个属性名 "carname",对应了视图中使用 {{ }} 中的名称。</p> <script type="text/javascript"> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.carTab = \'Volvo\'; }) </script> </body> </html>
AngularJS 应用组成如下:
View(视图), 即 HTML。
Model(模型), 当前视图中可用的数据。
Controller(控制器), 即 JavaScript 函数,可以添加或修改属性。
scope 是模型。
scope 是一个 JavaScript 对象,带有属性和方法,这些属性和方法可以在视图和控制器中使用。
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <form ng-app="myApp" ng-controller="myCtrl"> <input type="text" ng-model="name"> <h1>我的名字是 {{name}}</h1> </form> <p>当你修改输入框中的值时,会影响到模型(model),当然也会影响到控制器对应的属性值。</p> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.name = \'Miaomiao Tab\'; }); </script> </body> </html>
ng-repeat
<!-- "var x in names" : ng-repeat="x in names" --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> <ul> <li ng-repeat="x in names" ><h1>{{x}}</h1></li> </ul> </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.names=[\'tab\', \'ctrl\', \'shift\']; }); </script> </body> </html>
$rootScope
<!-- 所有的应用都有一个 $rootScope,它可以作用在 ng-app 指令包含的所有 HTML 元素中。 $rootScope 可作用于整个应用中。是各个 controller 中 scope 的桥梁。用 rootscope 定义的值,可以在各个 controller 中使用。 --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> <h1>姓氏为 {{lastname}} 家族成员:</h1> <ul> <li ng-repeat="x in names" >{{x}}</li> </ul> </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope, $rootScope) { $scope.names=[\'tab\', \'ctrl\', \'shift\']; $rootScope.lastname = \'Refsnes\'; }); </script> <p>注意 $rootScope 在循环对象内外都可以访问。</p> </body> </html>

Demo5:服务
服务(Service)是一个函数或对象,可在你的 AngularJS 应用中使用。
AngularJS 内建了30 多个服务。
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="lose"> <p>当前页面的url:</p> <h3>{{myUrl}}</h3> <p>使用$location服务获取当前页面的URL</p> </div> <script> angular.module(\'myApp\', []).controller(\'lose\', function($scope, $location) { $scope.myUrl = $location.absUrl(); }) </script> </body> </html>
http interval服务
$http 是 AngularJS 应用中最常用的服务。服务向服务器发送请求,应用响应服务器传送过来的数据。 AngularJS 会一直监控应用,处理事件变化, AngularJS 使用 $location 服务比使用 window.location 对象更好。 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="lose"> <p>欢迎信息:</p> <h3>{{myWelcome}}</h3> <p>$http服务向服务器请求信息</p> </div> <script> angular.module(\'myApp\', []).controller(\'lose\', function($scope, $http) { $http.get(\'welcome.htm\').then(function (response) { $scope.myWelcome = response.data; }); }) </script> </body> </html> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="lose"> <p>欢迎信息:</p> <h3>{{theTime}}</h3> <p>$http服务向服务器请求信息</p> </div> <script> angular.module(\'myApp\', []).controller(\'lose\', function($scope, $interval) { $scope.theTime = new Date().toLocaleTimeString(); $interval( function() { $scope.theTime = new Date().toLocaleTimeString(); }, 1000); }) </script> </body> </html>
自定义服务/使用自定义服务自定义过滤
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="lose"> <p>自定义服务:</p> <h3>{{hex}}</h3> </div> <script> var app = angular.module(\'myApp\', []); app.service(\'hexafy\', function(){ this.myFunc = function(x){ return x.toString(16); } }); app.controller(\'lose\', function($scope, hexafy) { $scope.hex = hexafy.myFunc(225); }); </script> </body> </html> <!-- wrong: var myFunc = function(x){return x.toString(16);} right: this.myFunc --> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" > <p>自定义过滤:</p> <h3>{{255 | myFormat}}</h3> </div> <script> var app = angular.module(\'myApp\', []); app.service(\'hexafy\', function(){ this.myFunc = function(x){ return x.toString(16); } }); app.filter(\'myFormat\', [\'hexafy\', function(hexafy) { return function(x) { return hexafy.myFunc(x); } }]); </script> </body> </html> <!-- app.filter(\'sd\',function(){}) : app.filter(\'sd\',[\'servc\',function(){}]) anonymous function apply <div ng-app="myApp" ng-controller="lose"> 用不到的控制器,不能放里面会报错-->
Demo6:select
这里起没有仔细的做——
ng-options 创建选择框
用ng-repeat 指令来创建下拉列表
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> <select ng-model="selectNames" ng-options="x for x in names"="x in names"></select> <p>ng-options</p> <select> <option ng-repeat="x in names">{{x}}</option> </select> <p>ng-repeat 指令</p> <p>数组做对象</p> <select ng-model="selectedSite"> <option ng-repeat="x in sites" value="{{x.url}}">{{x.site}}</option> </select> <select ng-model="selectedSite" ng-options="y.site for y in sites"></select> <h1>你选择的是:{{selectedSite}}</h1> <p>数据源做对象</p> <select ng-model="selected" ng-options="x for (x, y) in siteWeb"></select><br><br> <select ng-model="selectedCars" ng-options="x for (x, y) in cars"></select> <h1>你选择的是: {{selectedCars.brand}}</h1> <h2>模型:{{selectedCars.model}}</h2> <h3>颜色:{{selectedCars.color}}</h3> <select ng-model="selecteCars" ng-options="y.brand for (x, y) in cars"></select> <h1>你选择的是: {{selecteCars.brand}}</h1> <h2>模型:{{selecteCars.model}}</h2> <h3>颜色:{{selecteCars.color}}</h3> </div> <script> var app = angular.module(\'myApp\', []); app.controller(\'myCtrl\', function($scope) { $scope.names = [\'tab\', \'ctrl\', \'shift\']; $scope.sites = [ {site: "baidu", url:"http://www.baidu.com"}, {site: "runoob", url:"http://www.runoob.com"}, {site: "cnblogs", url:"http://www.cnblogs.com/"} ]; $scope.siteWeb = { site01: \'Google\', site02: \'baidu\', site03: \'cnblogs\', }; $scope.cars = { car01: {brand: \'Ford\', model: \'Mustang\', color: \'red\'}, car02: {brand: \'Flat\', model: \'500\', color: \'blue\'}, car03: {brand: \'Volvo\', model: \'XC\', color: \'black\'}, }; }); </script> </body> </html>

Demo10:模块
模块定义了一个应用程序
模块时应用程序中不同部分的容器
模块是应用控制器的容器
控制器通常属于一个模块
指令构造器
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" runoob-directive></div> <script> var app = angular.module("myApp", []); app.directive("runoobDirective", function() { return { template : "我在指令构造器中创建!" }; }); </script> </body> </html>
模块和控制器分别在js文件中
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> <p>{{firstName + " " + lastName}}</p> </div> <script src="myApp.js"></script> <script src="myCtrl.js"></script> </body> </html> //myApp.js var app = angular.module(\'myApp\', []); //myCtrl.js app.controller(\'myCtrl\', function($scope) { $scope.firstName = \'Miao\'; $scope.lastName = \'Tab\'; });
Demo11:表单
HTML 表单通常与 HTML 控件(input select button textarea )同时存在。
ng-app="myApp"
