OpenLayers.Control.MousePosition
A small control which displays the Longitude and Latitude of the current mouse position, by defualt in the lower right of the map viewport.
* Constructor
OpenLayers.Control.MousePosition({Object|options}) -- Creates a new MousePosition control.
* Parameters
element -- if not null, div in which to display the MousePosition
prefix -- html to precede the longitude value (default: '')
separator -- html to separate the longitude and latitude values (default: '
')
suffix -- html to follow the latitude value (default: '')
numdigits -- number of digits to the right of the decimal (default: 5)
granularity -- Don't refresh display if mouse has moved more than this (default: 10)
prefix, separator, and suffix are used to format the lon/lat values.
With:
prefix = 'Lon: '
suffix = '
Lat: '
suffix = ''
nudigits = 3
Lon/Lat is displayed as:
Lon: 95.123
Lat: 35.456
If the mouse has never been over the map, Lon/Lat will equal 0/0. If the mouse is over the map, Lon/Lat will equal the current mouse position. If the mouse has been moved off the map, Lon/Lat will equal the value displayed at the time the mouse was moved off the map.
If the mouse is moving slowly, the Lon/Lat will refresh continuously. If the mouse is moving rapidly, the refresh of Lon/Lat will be suspended until the mouse has slowed down or stopped. (Trying to update the Lon/Lat value while the mouse is in rapid movemement makes the movement of the mouse unacceptably jerky.)
