【问题描述】:
建议开发一个页面,您可以在其中展示 Google 地图的摘录,其中有几个标记在集群中组织(完成)。我没有使用 javascript 的经验,我需要的是无论是否单击按钮,都可以获得我的位置并自动获知地图上标记的哪个点离我更近。有人能帮我吗?
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 13,
center: {lat: 40.963308, lng: -8.594651}
});
// Create an array of alphabetical characters used to label the markers.
var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
// Add some markers to the map.
// Note: The code uses the JavaScript Array.prototype.map() method to
// create an array of markers based on a given "locations" array.
// The map() method here has nothing to do with the Google Maps API.
var markers = locations.map(function(location, i) {
return new google.maps.Marker({
position: location,
label: labels[i % labels.length]
});
});
// Add a marker clusterer to manage the markers.
var markerCluster = new MarkerClusterer(map, markers,
{imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
}
var locations = [
{lat: 40.962157, lng: -8.593313},
{lat: 40.962149, lng: -8.595695},
{lat: 40.960351, lng: -8.598922},
{lat: 40.967305, lng: -8.591450},
{lat: 40.961682, lng: -8.608136}
]
