我有使用MYSQL数据库和javascript的PHP代码,我使用java脚本显示带有标记的Google Map,其中代码根据它们的协调显示标记。
我有一些具有相同协调但ID不同的标记,因此地图只显示最后一个标记。
我需要的是:
或
<script type="text/javascript">
var map,currentPopup;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 8,
center: new google.maps.LatLng(33.888630, 35.495480),
mapTypeId: 'roadmap'
});
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
parking: {
icon: iconBase + 'parking_lot_maps.png'
},
library: {
icon: iconBase + 'library_maps.png'
},
info: {
icon: iconBase + 'info-i_maps.png'
}
};
function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
//icon: icons[feature.type].icon,
map: map
});
var markerCluster = new MarkerClusterer(map, marker,
{imagePath:
'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
var popup = new google.maps.InfoWindow({
content: '<b>Site ID :</b> ' + feature.info +'<br></br>'
+ '<b> Site Name :</b>' + feature.site_name +'<br></br>'
+ '<b>Coordinates :</b> '+ feature.position +'<br></br>'
+ '<b>height :</b> ' + feature.height,
maxWidth: 300
});
google.maps.event.addListener(marker, "click", function() {
if (currentPopup != null) {
currentPopup.close();
currentPopup = null;
}
popup.open(map, marker);
currentPopup = popup;
});
google.maps.event.addListener(popup, "closeclick", function() {
map.panTo(center);
currentPopup = null;
});
}
var features = [
<?php
$prependStr ="";
foreach( $wpdb->get_results("select c.siteID, c.latitude, c.longitude, c.height
, i.siteNAME
FROM site_coordinates2 c LEFT
JOIN site_info i
on c.siteID = i.siteID
where i.siteNAME = '".$site_name."'", OBJECT) as $key => $row) {
$latitude = $row->latitude;
$longitude = $row->longitude;
$siteid = $row->siteID;
$height = $row->height;
$siteName = $row->siteNAME;
echo $prependStr;
?>
{
position: new google.maps.LatLng(<?php echo $latitude; ?>, <?php echo $longitude; ?>),
info:'<?php echo $siteid;?>',
height: '<?php echo $height;?>',
site_name: '<?php echo $siteName;?>',
}
<?php
$prependStr =",";
}
?>
];
for (var i = 0, feature; feature = features[i]; i++) {
addMarker(feature);
}
}
</script>
<?php
//echo "</table>";
}
?>
我将此库添加到代码
<script src="https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/markerclusterer.js">
</script>
