复现步骤

import Taro from '@tarojs/taro'
import { View, Block } from '@tarojs/components'

function Demo () {
  const data = [{ id: 1, val: 'demo' }]
  const onClickDemo = () => {
    console.log(11)
  }
  const renderDemo = () => (
    <Block>
      {data.map(item => (
        // 不使用onClick则正常
        <View key={String(item.id)} onClick={onClickDemo}>
          {item.val}
        </View>
      ))}
    </Block>
  )
  
  return <View>{renderDemo()}</View>
}

export default Demo
