Flask with Fetch API and render_template - receive new rendered data
- you're not using fetch correctly at all
- you're setting a cors response header in a request
mode: 'cors'is the default for cross origin requests, but- you're request is same origin, so why are you messing with CORS anything
- no need to create that function or use async await
So
document.getElementById("search").addEventListener("click", function() { let token = new FormData(); token.append('search', document.getElementById('search_place').value); fetch('/stop', { method: 'POST', body: token }) .then(response => response.text()) .then(tables => $('.table').html(tables));});but if you insist on using async/await
document.getElementById("search").addEventListener("click", async () => { const token = new FormData(); token.append('search', document.getElementById('search_place').value); const response = await fetch('/stop', { method: 'POST',body: token} ); const tables = await response.text(); $('.table').html(tables));});
