react-native - React Native Flatlit - 数组中的 Keyextractor
问题描述
我想使用 Google 图书返回的 ISBN 代码将 keyextractor 用于平面列表：
"industryIdentifiers": [{ "identifier": "8870755312", "type": "ISBN_10" }, { "identifier": "9788870755312", "type": "ISBN_13" }],
我尝试过这样的事情但不起作用
keyExtractor={(item, index) => item.industryIdentifiers[1].identifier}
任何想法？谢谢
解决方案
