问题描述
通过map遍历数组,根据对应的template的值,分别显示对应的组件,h5中可以正常显示,小程序端不能渲染,而且也没报错

复现步骤

topicBlocks: [
  {
    "id":10045,
    "title":"重磅推荐",
    "template":1
  },
  {
    "id":10046,
    "title":"精品图书",
    "template":3
  },
  {
    "id":10047,
    "title":"热血玄幻",
    "template":4
  }
]

期望行为
根据 template的值,来显示对应的布局

报错信息

this.state.topicBlocks.map((item) => {
const temp = item.template == 1
return temp && 啊哈哈
})

h5: 可以正常显示
百度小程序:不能渲染,而且也没报错

当你这样写的时候实际上拿一个数组去渲染文本节点,百度小程序应该不支持直接这样渲染,我建议你需要这么写的时候用一个 Text 组件包起来

this.state.topicBlocks.map((item) => {
const temp = item.template == 1
return temp && <Text>啊哈哈</Text>
})
