<html ng-app> ng-app告诉Angular管理页面的那一部分。依据须要ng-app也能够放在<div>上 <body ng-controller="CartController"> Javascript类叫做控制器,它能够管理对应页面区域中的不论什么东西。 <div ng-repeat="item in items"> ng-repeat代表为items数组中每一个元素拷贝一次该DIV中的DOM,同一时候设置item作为当前元素,并可在模板中使用它。 <span>{{item.title}}</span> 表达式{{item.title}}检索迭代中的当前项,并将当前项的title属性值插入到DOM中 <input ng-model="item.quantity"> ng-model定义输入字段和item.quantity之间的数据绑定 <span>{{item.price | currency}}</span> <span>{{item.price * item.quantity | currency}}</span> 单位价格和总价格式化成美元形式。通过Angular的currency过滤器进行美元形式的格式化。 <button ng-click="remove($index)"> Remove </button> 通过ng-repeat的迭代顺序$index,移除数据和对应的DOM(双向绑定特性) function CartController($scope) { CartController 管理这购物车的逻辑,$scope 就是用来把数据绑定到界面上的元素 $scope.items = [ {title: ‘Paint pots‘, quantity: 8, price: 3.95}, {title: ‘Polka dots‘, quantity: 17, price: 12.95}, {title: ‘Pebbles‘, quantity: 5, price: 6.95} ]; 通过定义$scope.items,我们已经创建一个虚拟数据代表了用户购物车中物品集合,购物车是不能仅工作在内存中,也须要通知server端持久化数据。 $scope.remove = function(index) {$scope.items.splice(index, 1);}; remove()函数可以绑定到界面上,因此我们也把它添加到$scope 中 |
