Adress-Autofill im Formular

Adress-Autofill im Formular

Autofill ist für Bestell- und Anmeldeformulare gedacht: ein Textfeld, eine Vorschlagsliste, und die übrigen Felder (Hausnummer, PLZ, Ort) werden aus dem gewählten Vorschlag gefüllt. Jeder Vorschlag bringt seine Koordinaten schon mit.

    Code

    // Address autofill: type a street and number, pick a suggestion, the form fields fill themselves.
    const TOKEN = 'YOUR_TOKEN'; // your public token (mx_pk_…) from https://account.mapx.at
    // Adds the token to every request MapLibre makes to mapx.at (style, tiles, fonts, sprites), never to other hosts.
    const transformRequest = (url) => ({ url: /^https:\/\/([\w-]+\.)?mapx\.at\//.test(url) ? url + (url.includes('?') ? '&' : '?') + 'access_token=' + TOKEN : url });
    const AUTH = { headers: { Authorization: 'Bearer ' + TOKEN } };
    
    maplibregl.addProtocol('pmtiles', new pmtiles.Protocol().tile);
    
    const map = new maplibregl.Map({ transformRequest, container: 'map', style: 'https://api.mapx.at/v1/styles/streets', center: [13.8, 47.7], zoom: 6.5 });
    map.addControl(new maplibregl.NavigationControl());
    const f = Object.fromEntries(['street', 'housenumber', 'postcode', 'place'].map((k) => [k, document.getElementById(k)]));
    const list = document.getElementById('treffer');
    let marker;
    
    f.street.addEventListener('input', async () => {
      list.replaceChildren();
      if (f.street.value.trim().length < 3) return;
      try {
        const res = await fetch(`https://api.mapx.at/v1/autofill/suggest?q=${encodeURIComponent(f.street.value)}&limit=5&session_token=demo`, AUTH);
        if (!res.ok) throw new Error('HTTP ' + res.status);
        for (const s of (await res.json()).suggestions) {
          const li = document.createElement('li'), b = document.createElement('button');
          b.type = 'button'; b.textContent = s.full_address;
          b.addEventListener('click', () => {
            for (const k of Object.keys(f)) f[k].value = s[k] ?? '';
            marker?.remove();
            marker = new maplibregl.Marker().setLngLat(s.coordinates).addTo(map);
            map.flyTo({ center: s.coordinates, zoom: 16 });
            list.replaceChildren();
          });
          li.append(b); list.append(li);
        }
      } catch (e) { list.textContent = 'Error: ' + e.message; }
    });

    Speichern und im Browser öffnen. Es braucht nur MapLibre GL JS 4.7.1 und pmtiles 3.2.1 per CDN, dazu den öffentlichen Token (YOUR_TOKEN ersetzen), keinen Build.
