      $scope.goods=[{
        gname:"iphone8",
        num:"3",
        price:"999"

        var allPrice=0;
        for(var i=0;i<$scope.goods.length;i++){
          allPrice+=$scope.goods[i].price*$scope.goods[i].num;
        }
        return allPrice;
      };
      $scope.remove=function (index) {
        if(confirm('确定移除此项嘛？')){
