[OpenLayers-Users] Automatic zooming to map points based on elements selected from drop-down lists

[Jerome Freyre]

Hi Surya,

If you can recover coordinates of your elements in drop-down list, you can
call the function :
map.setCenter(new OpenLayers.LonLat(selectedElementLongitude,
selectedElementLatitude));


And if there is multiple element selected, you have to create a bounding box
and zoom to the extent:

// Create a bounds
bounds = new OpenLayers.Bounds();
// You can use a loop for for each selected eleement and assign their
lon/lat
bounds.extend(new OpenLayers.LonLat(4,5));
bounds.extend(new OpenLayers.LonLat(5,6));

// Zoom to the extent
map.zoomToExtent(bounds);


Sincerly,
Jérome
