I'm making a gallery, fullscreen. 
I want the user to able to swipe right and left on multiple pages, and on each page I got an image. 

Using this code seen below.
When I just take out "firstpage" and "secondpage" the code stops working and no swipes are registered. 

2. $( function() {
3. 
   
4.   $('body').bind("swipeleft", function(){
5.   $.mobile.changePage('firstpage');
6.    });  
7. 
   
8.   $('body').bind("swiperight", function(){
9.   $.mobile.changePage('secondpage');
10.    });  
11. 
    
12. } );

How do I get so that I can swipe right and left on every page? Without targeting each one like seen above

Kind regards
