在 React Native 中嵌套 map

[英]Nested map in react native

大家好,我是 React Native 的新手,我正在尝试创建包含详细信息的下拉列表。 下面是我的代码,第一个数组值正在显示,但经验数组值未显示请帮助我解决这个问题。

    import React from "react";
import { StatusBar } from "expo-status-bar";
import { Text, View, StyleSheet, TouchableOpacity } from "react-native";
const data = [
  {
    name: "Jude",
    position: "Developer",
    experiences: [
      {
        id: 0,
        job: "React UI Developer",
        period: "2017-2018",
        description:
          "I love Creating beautiful Smart UI with React js and styled components",
      },
      {
        id: 1,
        job: "React/ Redux UI Developer",
        period: "2017-2018",
        description:
          "I love Creating beautiful Smart UI with React js and styled components",
      },
    ],
  },
  {
    name: "Mikes",
    position: "Developer",
    experiences: [
      {
        id: 0,
        job: "React UI Developer",
        period: "2017-2018",
        description:
          "I love Creating beautiful Smart UI with React js and styled components",
      },
      {
        id: 1,
        job: "React/ Redux UI Developer",
        period: "2017-2018",
        description:
          "I love Creating beautiful Smart UI with React js and styled components",
      },
    ],
  },
];

function ExpandList(props) {
  return (
    <View style={styles.container}>
      {data.map(({ name, position, experiences }) => {
        return (
          <View>
            <Text>{name}</Text>
            {experiences.map((checkaa) => {
              <Text key={checkaa.id}>{checkaa.job}</Text>;
            })}
          </View>
        );
        
      })}
    </View>
  );
}


const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
  },
  mainList: {},
  subCategoryTwo: {
    fontSize: 90,
  },
});

export default ExpandList;

当我尝试获得经验数组值时,它什么也没显示,有一天我陷入了这个问题。

您的第二个 map 缺少 return 关键字,因此我将其修改如下:

function ExpandList(props) {
  return (
    <View style={styles.container}>
      {data.map(({ name, position, experiences }) => {
        return (
          <View>
            <Text>{name}</Text>
            {experiences.map((checkaa) =>{
               return <Text key={checkaa.id}>{checkaa.job}</Text>
            })}
          </View>
        );
        
      })}
    </View>
  );
}
