I have a javascript function that tries to determine whether a div is visible and does various processes with that variable. I am successfully able to swap an elements visibility by changing it's display between none and block; but I cannot store this value...

I have tried getting the elements display attribute value and finding if the the element ID is visible but neither has worked. When I try .getAttribute it always returns null; I am not sure why because I know that id is defined and it has a display attribute.

Here is the code of the two different methods I have tried:

var myvar = $(#mydivID).is(:visible);

var myvar = document.getElementById(mydivID).getAttribute(display);

Any guidance or assistance would be greatly appreciated.
