angular 复习
重复一个html元素：
<ul>
<li ng-repeat="x in names">
{{x}}
</li>
</ul>
验证用户输入
<form ng-app="" name="myForm" ng-init="myText = 'test@runoob.com'">
Email:
<input type="email" name="myAddress" ng-model="myText" required></p>
<h1>状态</h1>
{{myForm.myAddress.$valid}}
{{myForm.myAddress.$dirty}}
{{myForm.myAddress.$touched}}
</form>
所有的应用都有一个$rootscope,它可以作用在ng-app指令包含的所有html元素中。是各个controller中scope的桥梁。用rootscope定义的值，可以在各个controller中使用。
$http是angularjs中的有一个核心服务，用于读取远程服务器的数据。使用格式：
var app = angular.module('myApp', []);
app.controller('siteCtrl', function($scope, $http) {
$http({
method: 'GET',
url: 'https://www.runoob.com/try/angularjs/data/sites.php'
}).then(function successCallback(response) {
$scope.names = response.data.sites;
}, function errorCallback(response) {
// 请求失败执行代码
});
});
使用ng-option指令来创建一个下拉菜单
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-init="selectedName = names[0]" ng-model="selectedName" ng-options="x for x in names">
</select>
输入验证：
<form ng-app="myApp" ng-controller="validateCtrl"
name="myForm" novalidate>
<p>用户名:
<input type="text" name="user" ng-model="user" required>
<span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
<span ng-show="myForm.user.$error.required">用户名是必须的。</span>
</span>
</p>
<p>邮箱:
<input type="email" name="email" ng-model="email" required>
<span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
<span ng-show="myForm.email.$error.required">邮箱是必须的。</span>
<span ng-show="myForm.email.$error.email">非法的邮箱。</span>
</span>
</p>
<p>
<input type="submit"
ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||
myForm.email.$dirty && myForm.email.$invalid">
</p>
</form>
<script>
var app = angular.module('myApp', []);
app.controller('validateCtrl', function($scope) {
$scope.user = 'John Doe';
$scope.email = 'john.doe@gmail.com';
});
</script>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.names = ["Google", "Runoob", "Taobao"];
});
</script>
表格
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td>{{ x.Country }}</td>
</tr>
</table>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
$http.get("/try/angularjs/data/Customers_JSON.php")
.then(function (result) {
$scope.names = result.data.records;
});
});
</script>
angular的复选框，单选框以及数据绑定
<form>
Check to show a header:
<input type="checkbox" ng-model="myVar">
</form>
<h1 ng-show="myVar">My Header</h1>
<form>
选择一个选项:
<input type="radio" ng-model="myVar" value="dogs">Dogs
<input type="radio" ng-model="myVar" value="tuts">Tutorials
<input type="radio" ng-model="myVar" value="cars">Cars
</form>
页面切换：ng-route
angular路由云需我们通过不童的url访问不同的内容通过angular可以实现但也多视图的应用
例如：
<html>
<head>
<meta charset="utf-8">
<title>AngularJS 路由实例 - 菜鸟教程</title>
</head>
<body ng-app='routingDemoApp'>
<h2>AngularJS 路由应用</h2>
<ul>
<li><a href="#/">首页</a></li>
<li><a href="#/computers">电脑</a></li>
<li><a href="#/printers">打印机</a></li>
<li><a href="#/blabla">其他</a></li>
</ul>
<div ng-view></div>
<script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
<script src="http://apps.bdimg.com/libs/angular-route/1.3.13/angular-route.js"></script>
<script>
angular.module('routingDemoApp',['ngRoute'])
.config(['$routeProvider', function($routeProvider){
$routeProvider
.when('/',{template:'这是首页页面'})
.when('/computers',{template:'这是电脑分类页面'})
.when('/printers',{template:'这是打印机页面'})
.otherwise({redirectTo:'/'});
}]);
</script>
