param() |
| Examples |
void setup() {
size(100, 100);
// Read the value "51" from the following text embedded in an HTML page:
// <applet code="param_example" archive="param_example.jar" width=100 height=100>
// <param name="back" VALUE="51">
// </applet>
String bgcolorStr = param("back");
int bgcolor = int(bgcolorStr);
background(bgcolor);
} |
| Description |
Reads the value of a param. Values are always read as a String so if you want them to be an integer or other datatype they must be converted. The param() function will only work in a web browser. The function should be called inside setup(), otherwise the applet may not yet be initialized and connected to its parent web browser. |
