Can we set some event on touching spesific coordinate only when spesific page / desktop resumed or displayed?

for example: event A happening when I click 1,1 coordinate on PAGE 01, but nothing happened when I click 1,1 coordinate on PAGE 02.

note: I’m not set any object on 1,1 coordinate.

I post this question because I don’t know whether this kind of script will be applied on all pages or just on displayed page
