uniapp+vue3使用uni.navigateBack传值，uni.navigateTo接收值

页面1：
function chooseUser() {
  uni.navigateTo({
    url: '/pages/userList?name=' + schData.value.keyword,
    events: {
      chooseUser: ({ name, num }) => {
        console.log(7878, name, num)
      }
    }
  })
}

//==================================页面分割线====================================


页面2：
import { getCurrentInstance, nextTick, ref } from 'vue'
import { onLoad } from '@dcloudio/uni-app'

const { proxy } = getCurrentInstance()
const eventChannel = ref(null)
onLoad(async options => {
  await nextTick()
  schData.value.keyword = options.num
  eventChannel.value = proxy.getOpenerEventChannel()
})

const chooseItem = item => {
  uni.navigateBack()
  eventChannel.value.emit('chooseUser', { name: item.userName, num: item.num })
}
