Creates a map as a child of
something.provider is one of TYPE_
constants. optionsObject may contain:
fix - one of FIX_ constants,
used when markers are too close to each other
fixDistance - distance for shifting
markers
fixEpsilon - euclidean distance limit of
markers to be taken as identical (in degrees). The
specificOptions object may contain any
engine-specific options, such as
{draggableCursor:crosshair} for Google Maps.
Methods
OAT.Map::addTypeControl()
Adds a 'map type' control to the map.
OAT.Map::addMapControl()
Adds a 'map navigation' control to the map.
OAT.Map::setMapType(type)
Sets map type to one of MAP_
constants.
OAT.Map::centerAndZoom(lat,
long, zoom)
Pans the map to given lat and long
coordinates and zooms.zoom ranges from 0 (far) to 16
(close).
OAT.Map::setZoom(zoom)
Changes current zoom level.
OAT.Map::getZoom()
Returns current zoom level.
OAT.Map::addMarker(group,
lat, long, file, w, h, callback)
Adds a marker to the map. Marker belongs to marker
group group(any internal value) and is located at
coordinates specified in lat and
long.file specifies an image file name
(wandhare its dimensions), false when default image should be
used. Finally, callback is a function to be executed
when user clicks marker.
OAT.Map::removeMarker(marker)
Removes existing marker.
OAT.Map::removeMarkers(group)
Removes all markers which belong to group.
OAT.Map::openWindow(marker,
something)
Opens window, anchored to marker.something
is a DOM node to be appended into window.
OAT.Map::closeWindow()
Closes opened window.
OAT.Map::optimalPosition(pointArray)
Zooms map so all points specified in pointArray
(array of 2-element arrays) can be visible simultaneously.
OAT.Map::geoCode(address,
callback)
Performs a geocoding lookup of address. When result
is returned, callback is executed. Its only argument
is false when no result was found, or an array
of[lat,long].
