GeoGebra supports two scripting languages -- GGBScript and Javascript. Script is a sequence of actions which can be triggered by :

  • clicking or updating particular object
  • loading the file (in case of Javascript)
  • Javascript listeners (see Reference:JavaScript)

You can set this script via Scripting panel of Properties Dialog.

GGBScript

You can create scripts consisting of GeoGebra commands.

Example:
  • a is an integer-valued slider ranging from 1 to 3
  • list1={"red","green","blue"}
  • in properties of a set On Update script to SetColor[a,Element[list1,a]]
  • by moving the slider you change its color


JavaScript

JavaScript is a programming language used by many Internet technologies. Unlike GeoGebra Script, in Javascript the commands don't have to be executed as a simple sequence, but a control flow (if, while, for) can be used. For generic JavaScript you can find a nice tutorial on developer.mozilla.org. In GeoGebra, you can use special JavaScript commands which allow you to change the construction.

Example:


Complete list of available commands can be found in Reference:JavaScript. GeoGebra contains its own JavaScript engine. When exported as Dynamic Worksheet one can choose whether to use this engine or the one contained in browser applets.
