[OpenLayers-Users] Reset the zoom

[Andrew Stewart]

You can zoom to any scale on a button press using -

map.zoomToScale("25000")

Or you can use OpenLayers.Control.NavigationHistory for zooming to previous levels, it can be associated with a button and you can use nav.previous to go back 1 level (or more).

Also, if you define your map extent at the beginning of load and want to go back, get the Bounds of your map assigned to a variable, then just map.ZoomToExtent using that variable.

Subject: [OpenLayers-Users] Reset the zoom

I want to make a button for reset the zoom status. If some user use the zoom, will be possible to reset to the initial state.

How is the best way to do this using JavaScript?
