我已成功实施Google地图.但还有一件事要做.当用户点击地图(任何坐标)时,我需要检索经度和纬度数据.我的整个代码如下所示:

<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);
    }); …
