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.
- 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.

Description of command / feature needed. Please enter it instead of this template into Manual:Scripting. so that it's included also to the public namespace. For more details see Project:HowTo |
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.
