I have been working on a project which uses Vue.js for front end. I came across a scenario where we need to allow user to add more entry in their form.

Initial Approach

The first thought that come to my mind will be get the div#id of the element and append it dynamically through javascript

var parent = document.getElementById('parent')
var component = createComponent() // Assuming this return an Node element


However, since we are using Vue.js, it doesn’t feel natural to approach it this way.

With Vue.js

Instead, we can utilize the functionality of Vue.js, by using v-for and v-on:click.

      v-for="index in count"
      {{ index }}
    <button v-on:click="addComponent">Add</button>

export default {
  data () {
    return {
      count: 1
  methods: {
    addComponent () {
      this.count += 1
  1. Declare a counter
    • We first declare a data count with the initial value of 1.
  2. Use v-for to generate components
    • In our template tag, We loop through the component with v-for="index in count".
    • With the v-for shorthands, vue will generate from count times of the component. In this case, count act like range. For more detailed explanation, refer to the official documetation: v-for with a Range).
  3. Button to increase count
    • Then we create a Add button that execute addComponent on click. The addComponent method is fairly straightforward, just increase the count by 1.
    • When the user click the Add button, the count will be increased by 1, thus cause Vue.js to render additional component in our view.


With the combination of, count act as counter. v-for to generate the components, and addComponent method to increase the count, we are able to render new component into our view when the user click the button.

P.S. The solution is inspired by this forum post
