sisco70 / AsyncSpinnerButton.js
Last active May 26, 2021 13:32
While waiting for a slow file download, shows a spinner on the submit button.. Vanilla Javascript (Bootstrap not mandatory).
document.getElementById('submit_form').addEventListener('submit', async function (event) {
event.preventDefault();
let sub_btn = document.getElementById('submit_btn');
sub_btn.setAttribute('disabled', '');
let sub_btn_html = sub_btn.innerHTML;
sub_btn.innerHTML = '<span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span> ' + sub_btn_html;
try {
let response = await fetch(this.action, { method:'post', body: new FormData(this) });
if (response.ok) {
let [, filename] = response.headers.get('content-disposition').split('filename=');
