Bind file input to a button using Vue.js

You can do this:

HTML:

<input id="fileUpload" type="file" hidden>
<button @click="chooseFiles()">Choose</button>

Vue.js:

methods: {
    chooseFiles: function() {
        document.getElementById("fileUpload").click()
    },
...

EDIT - Update syntax:

methods: {
    chooseFiles() {
        document.getElementById("fileUpload").click()
    },
...

Simplest way to do this is to stylize a label element like a button, HTML only.
