我使用Google Maps API创建了三个标记。有没有办法可以为每个标记添加一个事件监听器,以便它们在相应的标记处于活动状态时可以独立工作?如果用户越来越接近标记,我想显示一条消息,特别是使用bounds_changed。我想继续给用户一个消息,直到他们达到比如5的缩放级别。
<script>
var map;
var score;
score = 0;
function initMap() {
var chicago = {lat: 41.8781, lng: -87.6298};
var indianapolis = {lat: 39.7684, lng: -86.1581};
var oklahomaCity = {lat: 35.4819, lng: -97.5084};
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 0.0, lng: 0.0},
zoom: 1
});
var chicagoMarker = new google.maps.Marker({
position: chicago,
});
var oklahomaCityMarker = new google.maps.Marker({
position: oklahomaCity,
});
var indianapolisMarker = new google.maps.Marker({
position: indianapolis,
});
if (score==0) {
chicagoMarker.setMap(map)
}
if (score==1) {
oklahomaCityMarker.setMap(map)
}
if (score==2) {
indianapolisMarker.setMap(map)
}
chicagoMarker.setVisible(false);
indianapolisMarker.setVisible(false);
oklahomaCityMarker.setVisible(false);
}
</script>

async defer></script>
答案 0 :(得分:0)
试试这个
google.maps.event.addListener(chicagoMarker, 'click', function(){
//do something
})
