Ways to retrieve all list items by utilizing refs

When it comes to accessing the parent ul, I am familiar with using this.$refs.listOfItems. However, I am unsure of how to retrieve all the li elements within the ul list.

While the typical JS approach involves using

document.getElementById("listOfItems").getElementsByTagName("li");
, I am curious about Vue.js helpers such as this.$refs.

<template>
  <ul id="listOfItems" ref="listOfItems">
    <li v-for="item in items">{{ item.name }}</li>
  </ul>
</template>

<script>
  export default {
    mounted: {
      let ul = this.$refs.listOfItems
      let lis =  // HOW TO GET ALL LIs using `this.$refs.listOfItems`
    }
  }
</script>

Answer №1

It looks like you may have intended to place the v-for directive on the <li> element instead of the <ul>. When using a ref on an element that is repeated with v-for, it will create an array containing all items.

<ul>
  <li v-for="item in items" ref="items">{{ item.name }}</li>
</ul>
this.$refs.items[0];  // References the first <li> element
