哪个是访问道具的正确方法?
which is the correct way to acces the props?
我想我没有正确访问 属性 src,这可以在像这样的一行中的所有对象中找到
标志:src={imgrep(1)} alt="altofem"
每当我尝试渲染它们访问 src 时,我都会收到错误 × typeerror cannot read 属性 of undefined (reading 'props')
自从这个错误来来去去,我已经卡了一个星期了:(,提前谢谢你!

休息一下,在您冗长的代码中,您可能会发现问题所在——我为您提供了两种类型组件中道具的基本可访问性(或如何访问它们)——Class 和功能。
