The API document says the 2nd argument (the one for zoom), is optional.
However, there are 3rd and fouth arguments. How to invoke such an API call?
Anyone please provide a correct syntax, thanks. Would it be like
map.setCenter(lonlat)? Or like map.setCenter(lonlat, undefined)? ....
setCenter
setCenter: function(
lonlat,
zoom,
dragging,
forceZoomChange
)
Set the map center (and optionally, the zoom level).
Parameters
lonlat
{OpenLayers.LonLat<http://dev.openlayers.org/docs/files/OpenLayers/BaseTypes/LonLat-js.html#OpenLayers.LonLat>}
The new center location.
zoom
{Integer} Optional zoom level.
dragging
{Boolean} Specifies whether or not to trigger movestart/end events
forceZoomChange
{Boolean} Specifies whether or not to trigger zoom change events (needed on
baseLayer change)
TBD: reconsider forceZoomChange in 3.0
