我已经成功地实现了Google地图。但还有一件事情需要做,就是当用户点击地图时(任何坐标),我需要检索经度和纬度数据。我的整个代码看起来像这样:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(<?=$decimalValueLon?>,<?=$decimalValueLat?>);
var myOptions = {
zoom: 17,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
// marker STARTS
var marker = new google.maps.Marker({
position: myLatlng,
title:"Click to view info!"
});
marker.setMap(map);
// marker ENDS
// info-window STARTS
var infowindow = new google.maps.InfoWindow({ content: "<div class='map_bg_logo'><span style='color:#1270a2;'><b><?=$row->bridge_name?></b> (<?=$row->bridge_no?>)</span><div style='border-top:1px dotted #ccc; height:1px; margin:5px 0;'></div><span style='color:#555;font-size:11px;'><b>Length: </b><?=$row->bridge_length?> meters</span></div>" });
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
// info-window ENDS
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>`
提前感谢!
