The function to focus on this.$refs[("p" + index)] element is not available

I need help transforming a div into an input box when clicked, allowing me to edit the post inside a loop.

Here is the button found on the post:

<a @click="setFocusEdit(index)" v-if="isAuthor(post)" href="#" >Edit Me</a>

And here is the specific div in question:

<div :ref="'p' + index"  class="post-description">
    {{post.description}}
</div>

This is the method I am using:

  setFocusEdit(index) {
    console.log('focusing on', index);

    this.$refs['p' + index].focus();
  },

However, I am encountering the following error message:

Uncaught TypeError: this.$refs[("p" + index)].focus is not a function

Could you provide guidance on resolving this issue?

Answer №1

When utilizing the v-for directive, it is recommended to use the ref attribute with a static name such as posts, which will give you an array of the referenced elements.

new Vue({
  el: '#app',
  data: function() {
    return {
      posts: [{
          title: "post 1",
          content: "content 1"
        },
        {
          title: "post 2",
          content: "content 2"
        }
      ],

    }
  },

  methods: {
    setFocusEdit(index) {


      this.$refs.posts[index].focus();
    }

  },
  mounted() {

  }

})
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>




<div id="app">
  <div class='col-md-4 mt-3' v-for="(post, index) in posts" :key="index">
    <textarea readonly ref="posts" class="post-description">
      {{post.content}}
    </textarea>
    <a @click.prevent="setFocusEdit(index)" href="#">Edit Me</a>
  </div>
</div>
