There are some elements in one of my app's pages whose height and
other style values I'd like to get as soon as possible, since I want
to use the values to calculate and set heights of other elements. And
I'd like to be able to either get the element's natural height or one
I set using CSS.
So, I'm doing something like [1]:
h =
document.defaultView.getComputedStyle(e,null).getPropertyValue("height");
where e is a pointer to my element.
But I find that if I do this right at the start of the onload
function, I get back a zero value, whereas if I do it a bit later
(e.g. after waiting for some ajax calls to complete), then I get the
proper value.
So when are these style values set? The reason for this is to avoid
what I do at the moment: compute the true height by hand and just have
a JavaScript variable initialised to that value.
[1] If/when I can sort this I can collect the border/margin/padding
values too.
