vue3 笔记

1、获取一个DOM元素的属性

  
  
<script>  
import { ref } from 'vue'  
  
export default {  
  setup() {  
    const myDiv = ref(null)  
  
    const getDistance = () => {  
      if (myDiv.value) {  
        const distance = myDiv.value.getBoundingClientRect().top  
        console.log('距离顶部的距离:', distance)  
      }  
    }  
  
    return {  
      myDiv,  
      getDistance  
    }  
  }  
}
