I'm hoping to implement some changes in the way the applet.script()
JavaScript command works.
New option for running scripts "synchronously":
var status = applet.scriptWait("select carbon;....")
Here the script runs "synchronously" meaning the JavaScript waits at
this point until script termination. The JavaScript "status" variable
is then filled with status information so that one could evaluate what
worked or didn't with the script. Compilation errors, messages,
measurments, "show" results, etc., would all be returned and could be
processed. OK, so no one should have a problem with that, I think.
And here's another:
var strError = applet.scriptCheck("select carbon;....")
This one just runs the initial compiling, but doesn't actually run the
script. So here we would return the error message if it resulted.
Now, here's the question. Do you want/not want:
var strError = applet.script("select carbon;....")
That is, have the script command return an error message if there is
one during compiling? The reason I ask is that this does seem to me
useful, but the problem might be if people have links that look like this:
<a
href="javascript:document.getElementById('jmolApplet0').script('select
carbon')">select carbon</a>
Because this will return a string now, which is different from
returning "nothing." In the <a> context, a javascript string return
will pop up a new window with the message in it. Instead, these would
have to be changed to:
<a
href="javascript:void(document.getElementById('jmolApplet0').script('select
carbon'))">select carbon</a>
I guess I could implement:
var strError = applet.scriptReturnError("select carbon;....")
and leave
applet.script("select carbon;....")
alone?
