有人提议开发一个页面,在该页面中显示Google Maps的摘录,其中有几个标记以簇的形式组织(完成)。我没有使用JavaScript的经验,我需要的是点击按钮或不按钮,可以获取我的位置并自动通知地图上标记的哪个点更靠近我。有人能帮我吗? 获取坐标,测量距离并对它们进行比较
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}
