Passing Parameters from the Web Page
« on: Aug 10th, 2003, 6:44am » |

Is it possible to pass parameters from the web page to proce55ing? I would like to imbed the same procesing app in a few diffrent web pages, but change some colors. i suppose i could recompile a different version of the same app for each page, but i would like to keep the download time of the site to a minimum.
thanks,
jason

AFAIK there's no direct Processing way to get parameters, but you can use the plain java syntax:
Code:void setup() {
try {
int bg = Integer.parseInt(getParameter("bg"),16);
int r = bg >> 16 & 0xff;
int g = bg >> 8 & 0xff;
int b = bg & 0xff;
background(r,g,b);
}
catch (Exception e) {
background(0); // default colour
}
} |

then add this tag below to the <applet> tag in your html document:
<param name="bg" value="ffcc00">

if you know a server side lanuage you can write the html document. and use the var as a variable for a parameter in the applet tag.
