Esa's Google Maps API examples. Auto Zoom Out

Geocoder

Detecting 'sorry' tiles.

• Try zooming closer (dblclick) or geocode a place
• 'Sorry' error message contains a <p> element
• Number of html <p> elements is read from the map container:
• <p> elements
• They appear within a few seconds
• If certain amount of <p> elements found, zoomOut() is triggered

Indicating "No Zoom In available"

• There is a control map behind the visible one
• It follows the visible map but its zoom is one level closer
• It is smaller and loads 9 tiles (main map loads 16 tiles)
• If certain amount of <p> elements found, the color of [Zoom in] button is changed (FF and Opera. Have no idea why not in IE)
• <p> elements
• Alert is for IE

Finding the [Zoom In] button.

• Div elements of map are scanned by their 'title' attributes
• Searching a div with a title that equals 'Zoom In'
