Tutoriel Javascript 1 : Créer des boutons

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Syntaxe Javascript de chaque bouton.
Le code se situe juste en dessous de celui de l'applet GeoGebra:

<input type="button" value="Cacher A" onclick="document.ggbApplet.setVisible('A', false);">

<input type="button" value="Montrer A" onclick="document.ggbApplet.setVisible('A', true);">

<input type="button" value="A rouge" onclick="document.ggbApplet.setColor('A', 255, 0, 0);">

<input type="button" value="A bleu" onclick="document.ggbApplet.setColor('A', 0, 0, 255);">

<input type="button" value="A et B bleus" onclick="document.ggbApplet.setColor('A', 0, 0, 255);

                                               document.ggbApplet.setColor('B', 0, 0, 255);">

<input type="button" value="A et B rouges" onclick="document.ggbApplet.setColor('A', 255, 0, 0);

                                               document.ggbApplet.setColor('B', 255, 0, 0);">

<input type="button" value="Supprimer A" onclick="document.ggbApplet.deleteObject('A');">

<input type="button" value="RAZ" onclick="document.ggbApplet.reset();">

<input onclick="tracedroite();" type="button" value="Afficher la droite (AB)" />


<input type="button" value="Effacer la droite(AB)" onclick="document.ggbApplet.deleteObject('D');">



Code de la fonction pour tracer la droite:

<script type="text/javascript">
function tracedroite()
{
var app = document.ggbApplet;
app.setRepaintingActive(false);
app.evalCommand("D=Droite[A,B]");
app.setRepaintingActive(true);
}
</script>
