Just to preface this whole thing-- I'm not even sure that the way I'm going about this is the most correct way to do it. Basically, I need to add an instance of a Vue ponent when the user clicks a button, expanding. I used this discussion in the vue.js forum to help. Unfortunately, triggering this insert function via a button click is not working. Console is showing an "addNewStop is not defined at HTMLButtonElement.onclick" error.

The HTML in my template:

<div id="newCont"></div>
            <button type="button" class="btn-primary" id="addStop" onclick="addNewStop()">Add Stop</button>

The script I'm calling:

  import Stops from '@/ponents/Stops'

  const ComponentCtor = Vue.extend(Stops)
  const ponentInstance = new ComponentCtor({})
  function addNewStop() {
    ponentInstance.$mount('#newCont')
  }

I will freely admit that I wasn't sure how to go about doing this in the first place, and have found surprisingly little information about how to insert new ponent instances. If there are other, better options I should be exploring beyond this, please let me know!

Edit:

Stops is actually a template containing form inputs, allowing the user to specify a delivery stop along a truck route. Here is its template:

• javascript
• function
• vue.js
• ponents

• declare one data property=stops : [], inside <div id="newCont">, add template like <stops v-for="(item, index) in stops" :key="index"></stops> – Sphinx Commented Jun 27, 2018 at 20:29

In most cases, trying to manipulate the DOM directly (e.g. by adding a ponent) is a sign that you're not using Vue.js as it was intended. Vue is data-driven, which means that your code should simply update the data, leaving the DOM manipulation to Vue itself. Your question doesn't provide enough details for a specific solution, but there are a couple of general approaches that might work.

If you have a number of Stop ponents in the DOM, and clicking on the button simply adds another, then use v-for to render the stops from data, and have the button click handler simply add another entry in the data array.

<template>
    <form>
        <fieldset v-for="(stop, index) in stops" :key="index">
            <stop v-bind="whatever"/>
        </fieldset>
        <button @click="onClick">Add one</button>
    </form>
</template>

<script>
export default {
    data() {
        return {
            stops: []
        };
    },
    methods: {
        onClick() {
            this.stops.push(/* whatever */)'
        }
    },
    ponents {
        Stop
    }
};
</script>
