Hi,
I'd actually like to see Prototype handle this edge case for you, but
as far as I know it doesn't.
There's an *undocumented* way you can check: The `document.loaded`
property. But that's undocumented and so subject to change from dot
release to dot release. (Not necessarily a big problem, it just means
you have to test it when you upgrade from [say] 1.6.1 to 1.6.1.1 or
1.6.2 or 1.7.0.)
So:
function callWhenDOMReady(f) {
if (document.loaded) {
f.defer();
}
else {
document.observe("dom:loaded", f);
}
}
Note that that calls the callback asynchronously (via Function#defer),
*not* inline, when the DOM is already loaded -- because the call would
be asynchronous if the DOM weren't loaded, so doing it that way in all
cases avoids any issues where the calling code assumes the call won't
have happened yet.
FWIW,
