Tim,
The code below is what that I use in Jmol.js. Internally it calls
_jmolFindApplet with an applet name and it searches ... first in the
current window and then starting at the top.
I am not using getElementById but instead use document.applets[] and
document[appletname] (which is exactly the same as document.appletname but
works better for me since appletname is a parameter)
Miguel
function _jmolFindApplet(target) {
// first look for the target in the current window
var applet = _jmolSearchFrames(window, target);
if (applet == undefined)
applet = _jmolSearchFrames(top, target); // look starting in top frame
return applet;
}
function _jmolSearchFrames(win, target) {
var applet;
var frames = win.frames;
if (frames && frames.length) { // look in all the frames below this window
for (var i = 0; i < frames.length; ++i) {
applet = _jmolSearchFrames(frames[i], target);
if (applet)
break;
}
} else { // look for the applet in this window
var doc = win.document;
// getElementById fails on MacOSX Safari & Mozilla
if (doc.applets)
applet = doc.applets[target];
else
applet = doc[target];
}
return applet;
}
