react-native - REACT NATIVE 回购之前购买的订单

Question

我想一次用很多产品回购我之前的订单。有什么方法可以解决这个问题吗？我尝试了很多方法，但似乎都不起作用。

            },
            {
                "SalesGoodsID": 3535908,
                "SalesSlipID": 1473767,
                "GoodsID": 8775,
                "GoodsSubID": 1,
                "GoodsName": "小口調色料金ニッペ800",

                "SpecialPriceID": 1,
                "Price": 800,
                "Carriage": 0,
                "Number": 2,
                
            }
        ]
    },

这是我的代码。我想在 [sales_goods] onClickCart(data) { const itemcart = { goods: data, quantity: data.Number, Price:data.Price }; 中添加所有产品

    AsyncStorage.getItem('cart')
    .then(datacart => {
        if (datacart !== null) {
        const cart = JSON.parse(datacart);
        cart.push(itemcart);
        AsyncStorage.setItem('cart', JSON.stringify(cart));
        } else {
        const cart = [];
        cart.push(itemcart);
        AsyncStorage.setItem('cart', JSON.stringify(cart));
        }
      
    })
    .catch(error => {
        alert(error);
    });
}

选择固定数组时，会增加1个产品

onPress={() => this.onClickCart(item.sales_goods[0])}>   

我的英语不是很好。谢谢
