Accessing an element inside a Vuejs component

The answer posted by @nils is for VueJS 1.x. The v-el directive was removed in newer versions. It was replaced by ref attribute.

To achieve that same result in VueJS 2.x, you should do the following instead:

<template>
  <ul class="list-group" id="criteria" ref="criteria" v-for="item in criteria">
    <li class="list-group-item">{{ item.name }}</li>
  </ul>
</template>

<script>
  export default {
    data() {
      return {
        criteria: []
      }
    },
    mounted() {
      console.log(this.$refs.criteria);
    },
    methods: {},
  };
</script>

You may find more info about that change in VueJS docs.

Here are the steps that worked for me:

1. Reference your $ref in the html element:

 <p ref = "myref">Welcome to myApp</p>

2. Define a boolean variable in the script:

shown = false

3. In the update life cycle hook, keep this code:

update(){

  if(this.shown){
       
     console.log(this.$refs.myref)
     your code
  
  }

}

4. Change the boolean to "true" inside your function like the below code:

test(){

this.shown = false
....
some code
....

this.shown = true // this will trigger the code written in the update hook

}

VueJS 1.x

You're probably easier off using the v-el directive, which allows you to map elements in your component to an vm property on this.$els.

Also, AFAIK, you shouldn't combine the template property with templates in the .vue file (assuming you are using .vue files, of course).

<template>
    <ul class="list-group" id="criteria" v-el:criteria v-for="item in criteria">
        <li class="list-group-item">{{ item.name }}</li>
    </ul>
</template>

<script>
    export default {
        data() {
            return {
                criteria: []
            }
        },
        ready() {
            console.log(this.$els.criteria);
        },
        methods: {},
    };
</script>
