[OpenLayers-Users] draw rectangle over the map

[Iswaria]

Hi, 

Now I have drawn the rectangle.  

One more query, Before drawing a rectangle, I want to clear/remove the
rectangles, if any. 

How to do it? 

Thanks.

It seems to me like the box handler returns a set of pixels describing 
the box, and that the code added gets the coordinates for this. 
  
I guess a simlpe approach is the use the coordinates  and construct a 
polygon geometry and then add this as a feature to a vector layer on the 
map, and then apply a style to make it look like the box.
