javascript - jQuery - Stop listening for scroll down -

-

so using code perform tasks when user scrolls:

function myfunction(){ var position = $(window).scrolltop();  $(window).scroll(function() {     var scroll = $(window).scrolltop();     if(scroll > position) {          // scrolling downwards          hypedocument.showscenenamed('section 2', hypedocument.kscenetransitioncrossfade, 1.1);     }     position = scroll; });  return false; }

but prevent down scrolling on 1 page. there anyway can whilst allowing scroll on other pages? tried using $(window).off("scroll"); blocks scrolling in both directions.

this disable scrolling:

$('html, body').css({     'overflow': 'hidden',     'height': '100%' });

to restore:

$('html, body').css({     'overflow': 'auto',     'height': 'auto' });

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
