Bob,
After reading your note, I think item 2 (my original note below) is the
trouble maker. Item 1 (my original note below) is simple Jmol script
that could really go directly in the load script - setting echo
characteristics, turning hover off, etc. Here's the JavaScript function
called via the timeout. I call this function on load and after every
model change. It does the following:
1) Gets the Jmol stoichiometric formula of the model.
2) Puts the Jmol formula into more standard notation, including treating
fragments as separate formulas delimited by +.
3) Places this modified formula in our stoichiometric calculator field.
Note: In addition to being a cute toy that I'm attached to, this
calculator field keeps track of how many models are in the window -
important to us.
4) Puts the Jmol SMILES for the model into a JavaScript global variable
via a Jmol Script callback. This is for model identity tracking via a
database.
function getFormula() {
var atomArr; var calcHold = ""; var fs = new Array(); var f = new
Array(); var j;
fs = jmolGetPropertyAsArray("moleculeInfo.mf");
try {
for (var i = 0; i < fs.length; i++) {
if (fs[i].indexOf(" ") > -1) {
atomArr = fs[i].split(" ");
for (j = 0; j < atomArr.length; j++) {
f[j] = atomArr[j];
}
if (f[0] == "H" && f[2] == "C") { atomArr[0] = f[2];
atomArr[1] = f[3]; atomArr[2] = f[0]; atomArr[3] = f[1]; }
fs[i] = atomArr.join(" ") + " ";
calcHold += fs[i].replace(/ 1 /g, "").split("
").join("") + "+";
}
}
document.getElementById("calcDisplay").value =
calcHold.substring(0, calcHold.length - 1);
calcWinTxt = calcHold.substring(0, calcHold.length - 1);
if (stateSet) { jmolScript("print {*}.find('SMILES')"); }
else {
jmolScript("echo;print {*}.find('SMILES');" + loadScpt);
}
}
catch (e) {
//alert(e);
jmolScript("boundbox {*};centerat boundbox;");
}
}
So that you have everything, here's the JmolScript call that precedes
the getFormula() call:
jmolScript("hover off;color label pink;select formalCharge <> 0;label
%C;set echo top left;font echo 16 sansserif;color echo yellow;echo;set
PickCallBack 'processPick';set MessageCallBack 'processMessage';select
*;set debugscript true");
You can see this timeout delay on our original model kit page by
checking the stoichiometric calculator display:
http://chemagic.com/web_molecules/script_page_large.aspx
The problem page (again the problem is random and not frequent) is our
new model exercise page (deeply under construction!):
http://chemagic.com/web_molecules/template.aspx
In the case of the new page, the calculator field is hidden. The command
calcon (followed by enter) in the command field shows this field. At
this point, only the first two exercise types in the Problem Menu are
active.
The getFormula() function is pretty important to us, but there may be a
better way to do it. Any suggestions welcome!

Bob,
My jmolInit() is pretty involved:
1) An immediate jmolScript() call.
2) A JavaScript setTimeout() that makes a jmolGetPropertyAsArray()
call and another jmolScript call.
Maybe that jmolInit() function is getting me into trouble.
I'm sure it is. You are messing with two queued calls and in between
those an asynchronous get property. Yeiks!
Can you show me that page?
