我需要Map下面的对象,如{ ...product.images[0] }{ ...product.type[0] }{ ...product.productPackages[0] },在我下面的代码。
这是我的目标:

export const customImage = [
  {
    status: false,
    image: null,
    price: 10,
  },
];

字符串
我进口了这个

import { customImage } from "@/utils/customImage";


但当前声明是错误的。[this one selectedCustomImage: customImage,](我得到了下面的错误这个Map)
类型“{状态:boolean;图片:无效;价格:数量;}[]“缺少类型”SelectedCustomImageType“中的以下属性:status、image、pricets(2739)
(属性)selectedCustomImage:SelectedCustomImageType
请帮助我正确Map这个数组。
这是我的代码:

看起来使用的对象应该是一个数组,你只是忘记了在这里索引它:

selectedPackage: { ...product.productPackages[0] },
    file: null,
    selectedCustomImage: customImage[0],

字符串
你还必须赋值一个空字符串而不是null。

export const customImage = [
  {
    status: false,
    image: '',
    price: 10,
  },
];


如果对象不需要是数组,请删除方括号:

export const customImage =
  {
    status: false,
    image:'',
    price: 10,
  };


然后完全删除map调用

<div className="grid grid-cols-2 gap-3">
  <CustomImageInput
    item={customImage}
