I have just completed the conversion of a java simulation to javascript. However, I cannot find a way to read and set values of variables and elements from the html page. In the old java flavour we used

NameOfApplet._setVariables('variable=x')

and

NameOfApplet._getVariable('variable')

With ejss I cannot do this. I found the pdf with the instruction for using e.g.

_view.plottingPanel.setProperty("Display","none");

but it does not work when used in the head of the document, gives error "_view is not defined".

What is the correct way to do this, get and set variables of the simulation from the html page?

Thanks in advance

George
