I am making a simple accordion menu in javascript. I'd like to be able to set the compact and expanded heights for the elements via the css max-height and min-height values. For some reason, when I try to retrieve the min-height and max-height of the elements in javascript for animation purposes, I get an empty string rather than, for instance, "500px" like it should. The max-height value is set in css, e.g.
#id {
min-height: 40px;
max-height: 500px;
}
is all set up, but when I put a debugging mechanism in my javascript such as
alert( item.style.minHeight );
it pops up an empty alert box. This happens in Firefox 3.6.2 and IE 8. Does anybody know why javascript refuses to be able to get an element's minHeight and maxHeight?
