problem with fullscreen from javascript

I have a problem when I want to enable the fullscreen in javascript:
kp=document.getElementById('krpanoSWFObject');
kp.set('fullscreen', true);
will always fail with this message "Uncaught Error: Error calling method on NPObject."


Has someone a solution?



Thanks

Hi,

first - you need to be sure that the krpano viewer is already loaded and ready,

either make callback from xml to js to inform your javascripts that krpano is ready,
e.g.
xml:

Source code

 
1

<krpano onstart="js( krpanoready() )">

js:

Source code

 
1
2
3
4

function krpanoready()
{
  ...
}


or check in js if there is already a "set" function and if not wait and try again:
e.g.

Source code

 
1
2
3
4
5
6
7
8
9
10
11
12
13
14

function dostuff()
{
  kp=document.getElementById('krpanoSWFObject');
  if(kp.set)
  {
	kp.set(...);
  }
  else
  {
 	setTimeout( dostuff(), 100 );
  }
}

dostuff();


second - changing the fullscreen mode is only possible as reaction of a user interaction (click, keypress) in the Flashplayer - that means a call from Javascript to change the fullscreen mode will not work - this is a Flashplayer security limitation,

best regards,
Klaus

you can check this viewer :
http://svl360.wemake.fr/virtualtour/cite_de_l_or/index.html


there is a span :
fullscreen


wait that the krpano starts (I will add the check later), when you click on the span, oyu will get the error.

Thanks for your reply

Hi,

your 'init' code happens to early (directly after the embedding call) - the flash embedding is asynchronous so you need to wait until it is done and the viewer is ready,

Hi Klaus,

I have changed my code in order to wait the flash to be ready :

and always the same bug...

Best Regards,

Hi,

what bug?
if you mean setting fullscreen from javascript - that will never work - see above - switching to fullscreen is only possible as reaction to an user event (click, keyboard press) INSIDE the Flashplayer,

best regards,
Klaus
