搜索没有位置的谷歌地图框

Search Google Maps Box without Places

本文关键字：谷歌地图 位置 搜索      更新时间：2023-09-26

如果我订阅了Google Maps API，但没有订阅Google Places API，那么是否可以从搜索项中找到位置点？

类似于这个CODEPEN的东西（使用位置）

(function() {
  var marker;
  var map = new google.maps.Map(document.getElementById('map'), {
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });
  var input = document.getElementById('search');
  var searchBox = new google.maps.places.SearchBox(input);
  
  google.maps.event.addListener(searchBox, 'places_changed', updateMap);
  function updateMap() {
    var places = searchBox.getPlaces();
    var place = places[0];
    var radius = 1000000;
    if (marker) { marker.setMap(null); }
    marker = new google.maps.Marker({
      map: map, title: place.name,
      position: place.geometry.location
    });
    var circle = new google.maps.Circle({
      center: marker.position, radius: radius
    });
    map.fitBounds(circle.getBounds());
  }
})();
<input id="search" type="text" placeholder="Search Here">
<h2/>
<div id="map"></div>

您可以使用地理编码服务来实现此目的：

Google Maps API为地理编码和根据用户输入动态反向地理编码。

示例

function initMap() {
    var marker;
    var map = new google.maps.Map(document.getElementById('map'), {
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });
    var btnSearch = document.getElementById('btnSearch');
    addEvent(btnSearch, 'click', function () {
        var input = document.getElementById('search');
        updateMap(map, input.value);
    });
}
function updateMap(map, address) {
    var geocoder = new google.maps.Geocoder();
    if (geocoder) {
        geocoder.geocode({ 'address': address }, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                //console.log(results[0].geometry.location);
                var result = results[0];
                var radius = 1000000;
                var marker = new google.maps.Marker({
                    map: map,
                    title: result.formatted_address,
                    position: result.geometry.location
                });
                var circle = new google.maps.Circle({
                    center: marker.position,
                    radius: radius
                });
                map.fitBounds(circle.getBounds());
            }
            else {
                console.log("Geocoding failed: " + status);
            }
        });
    }
}
function addEvent(element, evnt, funct) {
    if (element.attachEvent)
        return element.attachEvent('on' + evnt, funct);
    else
        return element.addEventListener(evnt, funct, false);
}
#map{
     width: 640px;
     height: 480px;
}
  <input id="search" type="text" placeholder="Search Here">
  <button id="btnSearch">Search</button>
  <h2 />
  <div id="map"></div>
  <script src="https://maps.googleapis.com/maps/api/js?callback=initMap"
                async defer></script>
