Undefined method error encountered within Vue.js nested ref structure

Question

Undefined method error encountered within Vue.js nested ref structure

My component structure is three levels deep and it's set up like this:

- container
  - section-1 // section1Ref
    - form-1 // form1Ref

The submit method in the container component will call the submit method in section-1 using this.$refs.section1Ref.submit().

Then, the submit method within the section component will trigger the submit method in the form-1 component by calling this.$refs.form1Ref.submit()

However, when I try to execute this.$refs.form1Ref.submit(), I encounter this error:

this.$refs.form1Ref.submit is not a function

Even though I have confirmed that it is defined in the methods object of the form-1 component.

This issue seems to arise specifically with a ref that is located three levels deep.

My experience with this code was successful, and I have included a sample of it below:

Vue.component('sec', {
  template: `
  <div>section
    <br>
    <form1 ref="form"></form1>
  </div>`,
  methods: {
    callSection() {
      this.$refs.form.callForm();
    }
  }
});
Vue.component('form1', {
  template: `<div>form</div>`,
  methods: {
    callForm() {
      console.log('am called inside form')
    }
  }
});

Vue.component('container', {
  template: `
  <div>
    <button @click="clickMe">Click me</button>
    <br>
    <sec ref="section"></sec>
  </div>`,
  methods: {
    clickMe() {
      this.$refs.section.callSection();
    }
  }
});

// create a new Vue instance and mount it to our div element above with the id of app
Vue.config.devtools = false;
Vue.config.productionTip = false;

var vm = new Vue({
  el: '#app'
});

<div id="app">
  <container />
</div>
