javascript - Change the type of events -

-

is possible change type of event in javascript?

in scenario triggering events jquery on canvas, on specific elements in rendered canvas, drawn shapes or images. 

mousemoveevent ---> [canvas] -> [find element] ---> mousemoveoverelementevent

basically catch onmousemove event on complete canvas with:

$('canvas').bind('mousemove'........

but dom not exist within canvas want transform (to chatch later in process) to:

$('canvas').bind('mousemoveoverelement'........ $('canvas').bind('mouseenteronelement'........ $('canvas').bind('mouseleaveonelement'........

and assign 

e.element = 'imageatacertainpositioninthecanvas'

i prefer pass modified event instead of assigning new callback.

you might want read issue of sprite , canvas , relative bad performances too.
