推荐答案
您的Google地图和标记的JavaScript代码应位于window.onload
函数内部
your javascript code of google map and marker should be inside window.onload
function
<script type="text/javascript">
var locations = <?php echo $locations ?>;
window.onload = function(e){
var map = new google.maps.Map(document.getElementById('regularMap'), {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i]['locationLat'], locations[i]['locationLong']),
visible: true,
map: map
});
marker.setMap(map);
}
}
</script>
更新: https://developers.google.com/maps/documentation/javascript/adding-a-google-map
您还可以在Google库加载中使用回调参数.
You can also use callback parameter in your google library loading.
<script>
function initMap (){
var map = new google.maps.Map(document.getElementById('regularMap'), {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i]['locationLat'], locations[i]['locationLong']),
visible: true,
map: map
});
marker.setMap(map);
}
}
</script>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>
