Hi Eduardo,
The officially supported way to do this is with one or more
lzSetCanvasAttribute() calls. The lzSetCanvasAttribute(name, value)
browser javascript API causes a canvas attribute to be set to a new
value, sending an attribute change event as usual. Note that you'll
have to use the LPS-generated HTML for this to work. Let me know how it
goes!

Hello folks, I have implemented some javascript functions to access
OpenLaszlo methods, using the approach adopted in Flash. But, I don't
how to call Flash functions passing arguments. In the source code bellow
is shown how to call a function in Openlaszlo from Javascript without
passing arguments. Somebody know how to accomplish it?
Thanks,
Eduardo Lopes.

movieID.SetVariable("_root.functionName", name);
movieID.SetVariable("_root.flag", *true*);
