Follow the middle track that starts with mobileinit to see what happens after initial document load.

This should load exactly after the mobileinit (override global settings), infact pagebeforechange should run at first after mobile init.

This is the initGeolocation functions:

And finally this

But the problem is that the var nogps is not set to true (i keep geolocation disactivated for testing). The change page happen only after i change manually page after the first load.

How should work? Every page change (and first load too) i check if I can get geolocation of user, if not i send to the "nogps" page. Can the problem be related to my geolocation function that need more time to operate?

This will run on EVERY page change for EVERY page.

Is that what you wanted to do?

getCurrentPosition() is  asynchronous. It returns immediately and you get the success or fail callback when you get the callback - some unpredictable time in the future.

jQuery Deferred objects and $.when() are quite handy for dealing with this sort of thing. You can get a callback when multiple asynchronous events have completed.

Here's an example where I am waiting for two events that might occur in any order to complete. When each callback completes, it calls it's corresponding Deferred object's resolve method. e.g. keyboardWillShowWasProcessed.resolve() .

.then() is also handy. You can perform a sequence of actions upon completion of callbacks. Example. In this example I use the j query.timeout plugin, which returns a Deferred object. The functions resizeContent and resizeCanvas  are both asynchronous and return Deferred objects that are resolved when they complete, as well.

So there is no way to get position before page is created because is a async function and can "answer" after page is loaded right?

It might happen before you page is initialized. It might happen after.

It might happen before mobileinit. It might happen after.

Asynchronous means asynchronous.

That's why Deferreds and $.when() are so handy. You can get a callback when some number of asynchronous events have been completed.

pagebeforeload gives you a Deferred object. You can choose to defer loading of the page until later. See the docs.

Not sure what you are trying to accomplsih.
