Hi Chris,
Thanks for your suggestions.
I'm not too sure about your suggestion 1 - perhaps a Jmol expert will
know how to check if Jmol has finished loading the molecule?
However, your suggestion 2 has got me somewhere. I modified my
javascript so that if 'jmolGetPropertyAsArray("atomInfo", "all")'
returns null or an empty list, my code uses 'setTimeout()' to call
itself again in 50 millisecs to try again. I added a function-scope
static counter variable to remember how many attempts it has made -
after 10 attempts it gives up and displays an alert to the user (to
prevent an infinite loop). This seems to work quite well. On average it
seems to need 2 to 3 attempts at this interval before Jmol is ready to
give the 'atomInfo' property back. I've never seen it fail after 10
attempts (half a second) and give up.
I'm not sure how stable/reliable this mechanism will be on different
browsers/systems, but it does seem to work for me. Thanks! :-)
I'd still be really interested to know if there's a simpler easier way
to achieve this using standard Jmol scripting though. There must be an
easier way?!
Thanks very much,
Ian
