Possible to get parameters when processing on web?
Aug 21st, 2007, 6:06pm  
I would like to put a Processing sketch on a web page,
but have it accept parameters, ... in the same way that
a flash applet can.

For example, with flash, you can do the following:

<ember src="http://www.server.com/applet/example.swf"
quality="high" bgcolor="#22FF22" width="500" height="300">

Does anyone know of a mechanism that would allow
a Processing sketch to get access to values of parameters like:
quality, bgcolor, width, height, etc. ?

thanks,
 David Jones

sounds like a job for param()

Thanks so much for the quick response.
param() works like a charm.

I noticed that Processing 0125 now exports applets by generating HTML that uses <OBJECT> instead of <APPLET> (which is now deprecated, so that's cool).

I also noticed that all the default <param> values generated by Processing have the following format:

Code:
<param name="image" value="loading.gif" />


where it could be put more concisely:

Code:
<param name="image" value="loading.gif">


I was curious why it generates " />" when the simpler ">" is all that is required.  Maybe it's just a stylistic thing.

the /> terminates the <param tag, depending on what's between the tag, it will validate xhtml
