var myApp=angular.module('myApp',[]);//定义一个控制器
var model={//model模块，里面主要包含了数据
money:0,
items:[

$scope.model=model;//注意一下，前面的model在HTML中是看不到的，$scope.model这个model是可以的 $scope是全局对象，注意
$scope.Add=function (newItem) {//添加内容
$scope.model.items.push({name:newItem.name,price:newItem.price});
}
$scope.sum=function() {//计算费用
var Sum=0;
angular.forEach($scope.model.items , function (item) {
Sum+=item.price*item.number;
} );
return Sum;
}
$scope.add=function(target) {
