Search Address Autocomplete with Link to a Map

If you are looking for Search Address Autocomplete with Link to a Map then you are at the right place. We are going to use the Leaflet JavaScript library to display those places in the map automatically that the user enters their desired address to search in the Textbox. You can use this program in your website or systems for the user to search their desired location or address that they want. User enter the address or location that they want, then it will display those places in dropdown element and they can select the address that they want to, and it will appear on the map automatically.

Creating Markup

Let's create markup, it consists one TextBox for the user where they can enter their desired address or location to search and our map.
  1. <div id="map_Contatiner">
  2. </div>
  3.  
  4. <input type="search" id="insert_Location" class="form-control" placeholder="Type an Address . . . . ." />

JavaScript Code

This script used to locate the address or location to display automatically on the map.
  1. <script src="places.min.js"></script>
  2. <script>
  3. (function() {
  4.   var placesAutocomplete = places({
  5.     container: document.querySelector('#insert_Location')
  6.   });
  7.  
  8.   var map = L.map('map_Contatiner', {
  9.     scrollWheelZoom: false,
  10.     zoomControl: false
  11.   });
  12.  
  13.   var osmLayer = new L.TileLayer(
  14.     'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  15.       minZoom: 1,
  16.       maxZoom: 13,
  17.       attribution: 'Map data © <a href="https://openstreetmap.org">OpenStreetMap</a> contributors'
  18.     }
  19.   );
  20.  
  21.   var markers = [];
  22.  
  23.   map.setView(new L.LatLng(0, 0), 1);
  24.   map.addLayer(osmLayer);
  25.  
  26.   placesAutocomplete.on('suggestions', handleOnSuggestions);
  27.   placesAutocomplete.on('cursorchanged', handleOnCursorchanged);
  28.   placesAutocomplete.on('change', handleOnChange);
  29.   placesAutocomplete.on('clear', handleOnClear);
  30.  
  31.   function handleOnSuggestions(e) {
  32.     markers.forEach(removeMarker);
  33.     markers = [];
  34.  
  35.     if (e.suggestions.length === 0) {
  36.       map.setView(new L.LatLng(0, 0), 1);
  37.       return;
  38.     }
  39.  
  40.     e.suggestions.forEach(addMarker);
  41.     findBestZoom();
  42.   }
  43.  
  44.   function handleOnChange(e) {
  45.     markers
  46.       .forEach(function(marker, markerIndex) {
  47.         if (markerIndex === e.suggestionIndex) {
  48.           markers = [marker];
  49.           marker.setOpacity(1);
  50.           findBestZoom();
  51.         } else {
  52.           removeMarker(marker);
  53.         }
  54.       });
  55.   }
  56.  
  57.   function handleOnClear() {
  58.     map.setView(new L.LatLng(0, 0), 1);
  59.     markers.forEach(removeMarker);
  60.   }
  61.  
  62.   function handleOnCursorchanged(e) {
  63.     markers
  64.       .forEach(function(marker, markerIndex) {
  65.         if (markerIndex === e.suggestionIndex) {
  66.           marker.setOpacity(1);
  67.           marker.setZIndexOffset(1000);
  68.         } else {
  69.           marker.setZIndexOffset(0);
  70.           marker.setOpacity(0.5);
  71.         }
  72.       });
  73.   }
  74.  
  75.   function addMarker(suggestion) {
  76.     var marker = L.marker(suggestion.latlng, {opacity: .4});
  77.     marker.addTo(map);
  78.     markers.push(marker);
  79.   }
  80.  
  81.   function removeMarker(marker) {
  82.     map.removeLayer(marker);
  83.   }
  84.  
  85.   function findBestZoom() {
  86.     var featureGroup = L.featureGroup(markers);
  87.     map.fitBounds(featureGroup.getBounds().pad(0.5), {animate: false});
  88.   }
  89. })();
  90. </script>
