I've written this basic javascript to set to divs to the height of my document.

code:
function setRails()  {

		docHeight = document.height;

		alert(docHeight);

		leftRail = document.getElementById("left");

		rightRail = document.getElementById("right");

		leftRail.style.height = docHeight + "px";

		rightRail.style.height = docHeight + "px";

	}



its run at onload. However docHeight always equals 0, how come?

Ok, I expanded the code a bit and it seems to work wel in both IE and Firefox. If it does err, it errs on the side of caution.

code:
function setRails()  {

		docHeightOne = document.documentElement.offsetHeight;

		docHeightTwo = document.body.scrollHeight;

		if (docHeightOne > docHeightTwo)

			docHeight = docHeightOne;

		else

			docHeight = docHeightTwo;

		leftRail = document.getElementById("left");

		rightRail = document.getElementById("right");

		leftRail.style.height = docHeight + "px";

		rightRail.style.height = docHeight + "px";

	}



Still, I'm a total novice to the DOM . I don't know why document.height doesn't give me the height of the document directly, and I may still be doin' stuff I shouldn't be doing here.

You can test this code out here: www.shootpool.info/test.html
