Summary: Jmol and Javascript
Initial Comment:
Hello.
Could it be posible to pass variables between
applications, like the actual script selected in a
JmolMenu object to a jmolLink. I've created a function
to make a clickable image in Jmol.js based on the
jmolLink function. I use it to load new data into the
applet, I would like to pass data from other controls,
like menus into this function along with the script I
use it for.
For example the value propertie from the select in the
jmolMenu function is an script Index instead of the
actual value.
I could do this by calling some objects in javascript
within a function:
document.myform.jmolMenux.options[document.myform.jmolMenux.selectedIndex].value;
but that doesn't return anythin.
If for example i pass the document.myform.jmolMenux as
a variable to the new function, wheter in Jmol.js or in
the html page if I try to return the typeof that
variable, it says its an object, but If i try to read
the variable itself it says its am [object]
PLz need advice form someone with javascript experience.
It makes the same effect if I pass two variables with
the form and the select jmolMenu

Ok thanks for the tip, I did some reading and using an array
I managed to pass the selected value to the function.
Anyway Here is What I want.
I want to crate a clickable image that loads new data into
the applet and also sends some other configuration
parameters as scripts along with the load command. In this
particular case it'll be spacefill information coming from
another control (a JmolMenu):
i.e.:
I create a jmolMenu instance on my html page by doin:
jmolMenu(array,1,"menuname"), then by using the
document.formname.menuname.selectedIndex propertie I can
pass to the image control wich option of the select is
actually selected so when I click on the image it will pass
that option to be added to the load script command for the
applet, so when I click the image it will send this:
load ../jmol/molecule.xyz;select option. Where select option
can be one of this: spacefill off, spacefill 20%, etc.
Here are the function and the call from the html page:
function jmolImageLoader3(script, src,id, list, value){
_jmolInitCheck();
var scriptIndex = _jmolAddScript(script);
if (id == undefined || id == null)
id = "jmolImageLoader3" + _jmol.ImageLoader3Count;
++ _jmol.ImageLoader3Count;
var t = "<img width=53 height=60 name='" + id + "' id='" + id +
"' onclick='javascript:_jmolClick(" +
"_jmolAddScript(" + script + ";" + list[value][0] + ")"
+ _jmol.targetText +
");' onMouseover='_jmolMouseOver(" +
"_jmolAddScript(" + script + ";" + list[value][0] + ")"
+ _jmol.targetText +
");return true;' onMouseout='_jmolMouseOut()' " +
_jmol.linkCssText + ">" + "src=" + src + ">"
if (_jmol.debugAlert)
alert(t);
document.write(t);
}
and the call:
jmolImageLoader2("load
../jmol/datos/moleculas/viagra.xyz","imagenes/viagra.jpeg","imagenviagra",spacefiller,menu.selectedIndex);
Description as follows:
menu is declared as this:
var menu =document.tamanos.menutam So tamanos is the form
name and menutam is the jmolMenu or actual select name and id.
spacefiller is an array containing the options for the jmolMenu.
i.e.
spacefiller = [["spacefill off","off"], ["spacefill 20%",
"20%"]]
The problem is when I do the onclik='javascript:_jmolClick
thingy...
it seems that you cant pass functions as variables inside
another function, like in C where I can go like.
function myfunction (anotherfunction(var1, var2))
I send a zip file with the site. (only the html, the images
and the Javascript file), the applet and data are missing.
Space reasons

hi,
it has been a while, but I think you need to do this with a loop. something
like this:
for (var i=0; i<document.myform.jmolMenux.options.length; i++) {
if (document.myform.jmolMenux.options.selected) {
value = document.myform.jmolMenux.options[i].value;
break;
}
}
hth,
tim d
