I cant for the life of me figure out why this doesn't work:
javascript:
//==================================//
// resize_middle //
//----------------------------------//
// Resizes the content and left //
// navigation div to make up the //
// remains of available space. //
//==================================//
function resize_middle()
{
min_height = (window.innerHeight - 276) + "px";
middle_left = document.getElementById("middle_left");
middle_right = document.getElementById("middle_right");
alert("its not going to work!");
alert("here goes...");
alert(min_height);
middle_left.style.minHeight = min_height;
alert("it works!");
middle_right.style.minHeight = min_height;
}
//==================================//
// event handlers //
//==================================//
window.onload = resize_middle();
window.onresize = resize_middle();
html(body & javascript bit in head shown only):
<script src="javascript.js" type="text/javascript" charset="utf-8"></script>
<body>
<div id="container">
<div id="central_column">
<div id="top_left">

</div>
<div id="top_right">

I'v used this before and have a working copy of some only slightly different code, but it works perfectly. I get the debugging alerts up until "it works!", which I don't get. Thanks in advance, ell.

You need this instead:
window.onload = resize_middle;
window.onresize = resize_middle;
Because as having it resize_middle() the function is processed immediately and the result is added to the event. You want the function itself to be added to the event so you leave off the () unless your function returns a function for the event to use.

You need this instead:
window.onload = resize_middle;
window.onresize = resize_middle;
Currently you're calling those functions and assigning their return value to the event. What you want is to assign the functions themselves to the events, and let the events call them.
Side note:
Unless the variables in resize_middle are defined elsewhere and you intend for them to be accessible to the outer scope, it is good practice to use the var keyword when defining new variables.
function resize_middle()
{
// Changed to use "var"
var min_height = (window.innerHeight - 276) + "px";
var middle_left = document.getElementById("middle_left");
var middle_right = document.getElementById("middle_right");
alert("its not going to work!");
alert("here goes...");
alert(min_height);
middle_left.style.minHeight = min_height;
alert("it works!");
middle_right.style.minHeight = min_height;
}
