vue3.0中使用nextTick
vue3.0
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
 
    }
 
 
}
页面上:
vue2.0
this.abc = false
this.$nextTick(() => {
   //你要执行的方法
     this.abc = true
})
