Vuejs: v-model array in multiple input
I have an input text field with a v-model attached, and every time someone hits the "Add" button, another input text get added to the DOM with the same v-model attached. I thought I'd then get an array of the v-model values, but it only gets the value of the first v-model input:
<div id="app">
<div id="references">
<input v-model="references" type="text">
</div>
<button @click="addReference">Add</button>
</div>
The html I append to the dom is triggered by the addReference method:
addReference: function(e) {
e.preventDefault();
console.log(this.references);
var inputEl = '<input v-model="references" type="text">';
$('#references').append(inputEl);
}
Is this something Vuejs can't do? Is there a different approach of gathering values from dynamic dom elements with Vuejs?
new Vue({
el: "#app",
data: {
references: "text"
},
methods: {
addReference: function(e) {
e.preventDefault();
console.log(this.references);
var inputEl = '<input v-model="references" type="text">';
$('#references').append(inputEl);
}
}
})
input {
display: block;
margin: 1px;
}

<button @click="addReference">Add</button>
</div>
You're thinking through DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.
It's kind of hard to tell in your exact situation but I'd probably use a v-for
and make an array of finds
to push to as I need more.
Here's how I'd set up my instance:
new Vue({
el: '#app',
data: {
finds: []
},
methods: {
addFind: function () {
this.finds.push({ value: '' });
}
}
});
And here's how I'd set up my template:
<div id="app">
<h1>Finds</h1>
<div v-for="(find, index) in finds">
<input v-model="find.value" :key="index">
</div>
<button @click="addFind">
New Find
</button>
</div>
Although, I'd try to use something besides an index
for the key
.

If you were asking how to do it in vue2 and make options to insert and delete it, please, have a look an js fiddle
new Vue({
el: '#app',
data: {
finds: []
},
methods: {
addFind: function () {
this.finds.push({ value: 'def' });
},
deleteFind: function (index) {
console.log(index);
console.log(this.finds);
this.finds.splice(index, 1);
}
}
});
<script src="https://unpkg.com/[email protected]/dist/vue.js"></script>
<div id="app">
<h1>Finds</h1>
<div v-for="(find, index) in finds">
<input v-model="find.value">
<button @click="deleteFind(index)">
delete
</button>
</div>
<button @click="addFind">
New Find
</button>
<pre>{{ $data }}</pre>
</div>
