Re: Iconize weather info and something else

[Kristian K. <zi...@zi...>]

Regarding the javascript...

You could include some javascript file that outputs the metar
information you're interested in. This javascript file would be a php
file that outputs javascript, eg. a string called 'metar' that contains
the metar information you would like to write on your page.
When the original page loads you check if 'metar' contains something or
not. If i does you output the metar otherwise your write 'Retriving
metar... Please wait'
This should work, but I haven't tried it :-)

Try it out or write back, the idea should be possible to accomplish.

Best,
Kristian
