current coordinates of an element

P: 35
is there a way in javascript to retrieve the current coordinates of an element on screen with respect to the page viewport as well as the screen.?
i'm having this case where i have an INPUT element inside a DIV element and i have to scroll vertically through the DIV to view it.I want to get its coordinates when it is visible on the screen (ie. the coordinates that typically make it visible)
before scroll

after scroll
y=384 // should be but it's always 2225.

i'm stuck on something else, what would i do to retrieve the coordinates of a KeyEvent?

hi ...

you may use the onscroll-event to observe the event - add that handler ... with that you may normalize the coordinates to your viewport. for that you may use the pageXOffset, pageYOffset and/or srcollLeft, scrollTop coordinates in IE ... so the scrolling moves the viewport and you may write a function that computes the visibility when the current scroll-position makes your element visible ...

kind regards
