这是Google地图搜索功能的代码片段,用于搜索特定位置。如何制作谷歌地图搜索功能,无需标记即可搜索特定位置。我研究了谷歌地图搜索框,但到目前为止,即使在Google Developers Website中,我研究的大部分标记都无法找到。
var searchBox = new google.maps.places.SearchBox(document.getElementById('searchmap'));
google.maps.event.addListener(searchBox,'places_changed',function() {
var places = searchBox.getPlaces();
var bounds = new google.maps.LatLngBounds();
var i, place;
for (var i = 0; place= place[i]; i++) {
bounds.extend(place.geometry.location);
marker.setPosition(place.geometry.location);
}
map.fitBounds(bounds);
map.setZoom(15);
});
google.maps.event.addListener(marker,'position_changed', function(){
var lat = marker.getPosition().lat();
var lng = marker.getPosition().lat();
$('#lat').val(lat);
$('#lat').val(lat);
});

以下是来自Places search box页面的已修改示例,其中演示了如何利用Google地方自动填充功能(删除使用标记标记地点的依赖关系)
function initAutocomplete() {
var map = new google.maps.Map(document.getElementById('map'), {
center: { lat: -33.8688, lng: 151.2195 },
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var input = document.getElementById('searchmap');
var searchBox = new google.maps.places.SearchBox(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
searchBox.addListener('places_changed', function () {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
var bounds = new google.maps.LatLngBounds();
places.forEach(function (place) {
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
});
map.fitBounds(bounds);
});
}
