GeoGebraWeb Applets

With GeoGebra 4.2 we have introduced pure HTML5 GeoGebra documents. This way GeoGebra applets start even faster than before, and this technology provides availability of GeoGebra for smartphone users as well since Java is no longer a prerequisite. The main advantage is that GeoGebra runs on a wider set of hardware at a more comfortable speed, but to harness all the possibilities one should always use the latest web browsers. In short, we call this technology GeoGebraWeb, and the documents created by this method are called GeoGebraWeb Applets.

There are two types of GeoGebraWeb Applets: online and offline. Online documents are usually on GeoGebra; and offline documents are usually put on intranet servers by members of the GeoGebra community, or even on the end users' own machine.

Online documents

We suggest using online documents everywhere! GeoGebra automatically detects a user's web browser and decides if it is running on a smartphone, and serves the document in GeoGebraWeb format. Hence we strongly suggest to upload all your documents to GeoGebraWeb if you want to publish teaching materials. This has a great advantage: GeoGebra will always show the latest GeoGebraWeb document when a user wants to visit it on their smartphone.

How GeoGebraWeb works

GeoGebraWeb consists of a set of files which can be downloaded manually from http://dev.geogebra.org/download/web/GeoGebraWeb-latest.zip. However, these files are not intended for end users. For those who are still interested in the internal details, and want to tweak the HTML files, we provide some additional information here.

An HTML document may contain several GeoGebraWeb documents. The HTML file should look something like this:

 <script type="text/javascript" language="javascript" src="http://www.geogebra.org/web/4.2/web/web.nocache.js"></script>
 <article class="geogebraweb" data-param-width="600" data-param-height="400"
 data-param-showResetIcon="false" data-param-enableLabelDrags="false" data-param-showMenuBar="false"
 data-param-showToolBar="false" data-param-showAlgebraInput="true"
 data-param-ggbbase64="UEsDBBQACAAIAHOOh0AAAAAAAAAAAAAAAAAWAA...==">

Here we omit the beginning and closing parts of a typical HTML file and focus only the GeoGebraWeb parts. First of all, the GeoGebraWeb source must be loaded. For online documents the src must be http://www.geogebra.org/web/4.2/web/web.nocache.js, for offline documents its correct setting is web/web.nocache.js. The data-param-width and data-param-height settings should be the desired applet size in pixels. The other parameters are direct settings for GeoGebraWeb. Finally, the data-param-ggbbase64 setting must contain the .ggb file in base64 encoding (as generated by GeoGebra).

If you are a web developer, you can learn even more on this technology on the GeoGebra Developer Site.es:Creando Documentos HTML5 con GeoGebraWeb it:Tutorial:Creare documenti HTML5 con GeoGebraWeb
