Vuejs - Proper way to clone an element, and append to DOM - vue.js

Question

I have a HTML input field to enter some information:
<div id="fruitForm">
<div class="inputArea">
<label for="fruit0">Enter Fruit Name</label>
<input id="fruit0"></input>
</div>
</div>
<button #click="newInputField">Add More Fruit Input Fields</button>
<button #click="submit">Submit Fruit</button>
And then I handle that click event:
export default {
data() {
return {
}
},
methods: {
newInputField() {
//Create another input area for users to input fruits
},
submit() {
//Do something here
}
}
}
When a user selects the Add More Fruit Input Fields button, it should create a new input area so that the HTML looks like this:
<div id="fruitForm">
<div class="inputArea">
<label for="fruit0">Enter Fruit Name</label>
<input id="fruit0"></input>
</div>
<div class="inputArea">
<label for="fruit1">Enter Fruit Name</label>
<input id="fruit1"></input>
</div>
</div>
<button #click="newInputField">Add More Fruit Input Fields</button>
<button #click="submit">Submit Fruit</button>
Now, I've been using traditional DOM manipulation methods via vanilla Javascript to accomplish this... stuff like this:
const inputArea = document.getElementsByClassName('inputArea');
And then I change the id's of the input field, and then I use appendChild to add the new input field to the DOM.
So my question is: how should I be cloning this element with vuejs? I feel I'm not approaching this in the vuejs way. Should I be approaching this like a list and using v-for? Or something else?

Answer 1

Avoid direct DOM manipulations with Vue. You can use data property as a model for your template. The answer would be yes, you can and probably should use v-for for what you call cloning:
var demo = new Vue({
el: '#demo',
data: {
counter: 0,
inputs: [{
id: 'fruit0',
label: 'Enter Fruit Name',
value: '',
}],
},
methods: {
addInput() {
this.inputs.push({
id: `fruit${++this.counter}`,
label: 'Enter Fruit Name',
value: '',
});
}
}
});
<script src="https://unpkg.com/vue#2.5.16/dist/vue.js"></script>
<div id="demo">
<div class="inputArea" v-for="input in inputs" :key="input.id">
<label :for="input.id">{{input.label}}</label>
<input :id="input.id" v-model="input.value"></input>
</div>
<button #click="addInput">Add input</button>
</div>
