问题回答

Seems to me, 你回过头看像MarkerClusterer

EDIT

我看到——我没有清楚地看到原来的问话。

你们需要做的是将目前的排位/锁箱送给服务器,并在你本人的惠誉条款中使用这些价值。

这里的快速例子

// Create a GMap2 instance
var gmap = new GMap2( document.getElementById(  map  );

// Do all your setup here, like gmap.setCenter() and such

// Now, load the map data
loadMapFromCurrentBounds( gmap );

// Assign a handler to the "moveend" event
GEvent.addListener( gmap,  moveend , function()
{
  loadMapFromCurrentBounds( gmap );
});

function loadMapFromCurrentBounds( gmap )
{
  // First, determine the map bounds
  var bounds = gmap.getBounds();

  // Then the points
  var swPoint = bounds.getSouthWest();
  var nePoint = bounds.getNorthEast();

  // Now, each individual coordinate
  var swLat = swPoint.lat();
  var swLng = swPoint.lng();
  var neLat = nePoint.lat();
  var neLng = nePoint.lng();

  // Now, build a query-string to represent this data
  var qs =  swLat=  + swLat +  &swLng=  + swLng +  &neLat=  + neLat +  &neLng=  + neLng;

  // Now you can use this query-string in your AJAX request  

  // AJAX-stuff here
}

然后,在PHP结束时,假定您的数据表有latlng栏,如此。

$swLat = mysql_real_escape_string( $_GET[ swLat ] );
$swLng = mysql_real_escape_string( $_GET[ swLng ] );
$neLat = mysql_real_escape_string( $_GET[ neLat ] );
$neLng = mysql_real_escape_string( $_GET[ neLng ] );

$query = "
SELECT *
  FROM [Table]
 WHERE lat > $swLat
   AND lat < $neLat
   AND lng > $swLng
   AND lng < $neLng
";
