evalCommand("a= Slider(0, 1)") not working in offline embedded applet

Hi,

thanks for all the great work you do!


When I open the attached file in chrome, the circle is added to the applet but the slider is not.

However executing:

ggbApplet.evalCommand("a=Slider(0,2)");

in the browser console directly, will add the slider.

Changing

ggbApplet.evalCommand("a=Slider(0,2)");

to:

ggbApplet.evalCommand("a=1");

in index.html will only produce a default slider.


What'S the correct way to add a custome slider to an embedded applet?

You have to use the correct GGb-command-syntax for slider:

ggbApplet.evalCommand('a=Slider(0,5,0.1,1,250,false,true,false,false)')

Still doesn't work for me. I tried this in Chrome, Firefox and Edge.

using this line:

retVal = ggbApplet.evalCommand('a=Slider(0,5,0.1,1,250,false,true,false,false)');

in my index.html file will return false.

when entering the line in the browser console it returns true and adds the slider.

Ok after running a test with your index.html file i can confirm that it will not create slider by the slider-command.

I tried to get the command of slider a after generating it manually with ggbApplet.getCommandString('a') and it returns "".

And by adding the parameters "showLogging": true, you can see: Command not loaded yet which might give you the hint that "appletOnLoad" might not be the right place to script yet?

Use the JS command asyncEvalCommand(). Not sure though if it is the right way to script the applet at startup and not load it with ggbBase64 or material_id (Reference:GeoGebra Apps Embedding).

Yes, that's it!

Probably, the prefered way is to load an existing file or material.

Since asyncEvalCommand is not mentioned in the reference, one can only guess.

For me it works!


Thanks!


- not sure how to mark this as answered -

The bug with evalCommand() is fixed, please try now


Please don't use asyncEvalCommand(), that's experimental and will probably be removed soon
