Thanks Niphlod, Cliff, and Anthony for your helpful replies. :D
I have just successfully controlled a LED lamp after understanding the URL
and arguments. I am so happy!!
here are my codes for your inspection :D
in test.html
<a href = "{{=URL('test', args =['bulb','1', 'on'])}}"><img src
="/Comfort2/static/images/on.jpg" width ="75" height="75"></a>
<a href = "{{=URL('test', args =['bulb','1', 'off'])}}"><img src
="/Comfort2/static/images/off.jpg" width ="75" height="75"></a>
in default.py
if request.args(1)== '1' and request.args(2)=='on':
serialport.write("\x03O!0101\x0D")
elif request.args(1)== '1' and request.args(2)=='off':
serialport.write("\x03O!0100\x0D")
Attached is a work-in-progress cherrypy script. it has the jQuery keypad (i
got it from here http://jsfiddle.net/pjaaar/6Zh2V/ ). i was wondering if i
could use jquery in web2py, the web page may seem more interactive. But i
don't mind doing 2 different interfaces for cherrypy and web2py. :D
Afterall, learning all these are getting more exciting.
