         }
            $("#divtoshow").css('position',"absolute");
            $("#divtoshow").css('top',popup_pos.top-120);
            $("#divtoshow").css('left',popup_pos.left-120);
            //~ $("#divtoshow").show();
     });    
    $("#divtoshow").live('mouseleave', function() {

            $(this).remove();

         });
});
</script>

Q why on mouseleave the divtoshow is not hiding it hide when i again mouseover it .

You need some modificiations there:

change 'mouseover' to 'mouseenter'
use a .live() binding for #divtoshow
access elements within event handlers via this

Example: http://www.jsfiddle.net/YjC6y/23/

Either you can remove divtoshow on mouse leave event by

  $("#divtoshow").remove();

Or on mouse over event of popupContact div, first check existence of divtoshow, and if not exists then append it i.e.

      if($("#divtoshow").length==0){
           $("#popupContact").append('<div id="divtoshow" style="display:block;background-color:green; border:1px solid black;width:200px;height:100px;position:absolute;">'+
 'dsfdssd <div><a href="#">rahul</a></div>'+
 '</div>')
      }
      // css statements will come here

I have done it by myself , i have seen the solutions of others they are good thanks to them for answering .
