Javascript Airport weather decoder

While weatherpixie remains on extended hiatus, I have finally put together a simple in-browser replacement. It uses James Padolsey's cross-domain Ajax plug-in for jQuery (indirecting via YQL), a simple parsing script from Manuel Heras, here separated into a stand-alone script, and an iframe-based page to do the work.

The final piece of heavy lifting is to get the appropriate METAR report for the local airfield, and that's just a few lines of javascript --

	$(document).ready(function(){
	var lmurl = "http://weather.noaa.gov/mgetmetar.php?cccc=EGSC&Submit=SUBMIT"
	$.get(lmurl, function(res) {
	$(res.responseText).find('hr + p').each(function(i, a) {
	var text = a.innerText;
	if (text == undefined) text = a.textContent;
	text = do_metar(text);
	while (text.indexOf('\n') >= 0)
	text = text.replace('\n', '< br />');
	$('#report').html(text);
	});
	});
	});

Here, EGSC is the ICAO code for Cambridge Airport. And that's a lot closer to home than the Met. Office who give out current conditions at Bedford on the Cambridge forecast!
