This is a common mistake.
Until you've explicitly set the style property via JS or the style
attribute in the markup, show.style.display will be undefined, not "none"
or any other CSS value you might expect. That's why your current script
takes 2 clicks: The display property first goes from (undefined) to "none"
then finally "block". To suit your purposes, this would work:
show.style.display =
(!show.style.display || show.style.display=="none")? "block" : "none";
The general way to get a "computed" style requires you to use
window.getComputedStyle or IE/win's currentStyle. Here's one such function:
