vue3中使用nexttick

1、引入

import { nextTick } from 'vue'

2、具体使用，配合异步

setup() {
    const message = ref('Hello!')
    const changeMessage = async newMessage => {
      message.value = newMessage
      await nextTick()
      console.log('Now DOM is updated')
    }
  }

3、具体使用，普通

方法里：

 setup () {    
    let otherParam = reactive({
      showA:false
    })
    nextTick(()=>{
      otherParam.showA = true
    })
  return {
      otherParam
 
    }
 
 
}
