I am not sure if I understood your problem correctly but it shouldn't be
a problem to pass parameters to a Jmol function call (see the Jmol
scripting documentation:
http://chemapps.stolaf.edu/jmol/docs/#functionsuser-definedfunctions).
Example Jmol function:
function my_print(my_text) {
echo my_text;
}
Example Javascript call:
var my_javascript_text = "passed from javascript";
jmolScript("my_print(" + my_javascript_text + ")");
I havn't tested this myself but would expect it to work.
Depending of the type of parameters of the Jmol function you might have
to adapt them to being called from javascript.
If you would have for example a "point" variable (see
http://chemapps.stolaf.edu/jmol/docs/#jmolmathjmolvariables) in Jmol
script ("pt={3.2,3.3,3.4}") it might be necessary to pass the x,y and z
value as separate paramters 'x', 'y', 'z' instead of as the single
parameter "{3.2,3.3,3.4}".
