Issue with touch interfacing

I wanted to implement touch individually for these features. I posted this on the forum and they suggested I implement it in this manner.

Bangle.on('touch', function(n,event) { 
if(event.y<60){
walking_subactivity();
}  
else if(event.y>=60 && event.y<120){
jogging_subactivity();
  }
else
  {
cycling_subactivity();
  }
});

The issue now is that once I am on the working screen, if I click on the middle portion of the touch screen it takes me to the jogging screen. My main issue is that once I choose the walking option, the screen should remain there even if I click at some other part of the screen and do not jump to the jogging and cycling screen.

I have written the function names in the if-else condition in order to make the code a bit more readable for the sake of this doubt.

Thank you in advance.

I believe you should remove the listener used for selecting mode once you've made the selection, in your example function(n, event). I don't know, but I suspect you might need to break function(n, event) out into a function with it's own name to make it work, maybe

function selectOnTouch(n, event) { ... }
...
Bangle.removeListener('touch', selectOnTouch);

and then your code would be something like

function selectOnTouch(n, event) { 
if(event.y<60){
walking_subactivity();
Bangle.removeListener('touch', selectOnTouch);
}  
else if(event.y>=60 && event.y<120){
jogging_subactivity();
Bangle.removeListener('touch', selectOnTouch);
  }
else
  {
cycling_subactivity();
Bangle.removeListener('touch', selectOnTouch);
  }
});

Bangle.on('touch', selectOnTouch); //start the listener for touch input here

I'm not 100% on these things though - but I think that's basically how it works. This is relevant I think: http://www.espruino.com/Reference#l_Object_removeListener

I hope I'm not leading you astray with this :P

@Ganblejs It works exactly as I want it to work. Thank you very much, I have been stuck on this for days and it finally works!!

Nice! I just recently learned about removing listeners myself - it was something of a revelation. :)
