"I don't think we need to replicate functionality provided by javascript
libraries."
Tapestry provides onDOMLoaded and waitForPage .. the functionality I
describe isn't provided by Tapestry or a javascript library (since the
js lib would need to know about the Tapestry js api).
I'm not sure what you mean by that statement Josh, I'm proposing a
useful utility method inseparable from the tapestry js api so that other
users don't have to write and embed the method themselves also.

Callbacks are closures, why do you need parameters?
If something like this doesn't exist in tapestry already, I think it should.
I don't think we need to replicate functionality provided by
javascript libraries.

if (Tapestry.pageLoaded)
callback.call(this);
else
Tapestry.onDOMLoaded(callback);

Hi all,
i'm using tapestry 5.1.0.5 on this particular project.
I'm not 100% sure this isn't already available, but before duplicating
logic i thought I'd check...
I need to be able to call a function at any point in the page state (ie
before it's loaded, during loading, after load) but have it wait until
tapestry.init has been called.
Kind of how Tapestry.waitForPage works, except that if the page has not
loaded, instead of showing a dialog, it would register it for invoking once
the page is loaded.
so in psuedo:
function(callback)
{
if(Tapestry.pageLoaded)
invoke(callback);
else
Tapestry.onDOMLoaded(callback);
}
2 questions:
a) is this functionality already available? where?
b) would the above approach be fool-proof? ie would there be a case where
Tapestry.pageLoaded == false and Tapestry.onDOMLoaded would still not invoke
the callback?
thanks, p.
