javascript - JQuery Offset Script -


i creating navigation menu website. when user scrolls past point 497px needs change colour. have wrote script: 

$(document).ready(function(){      function checkoffset() {       var offset = $(document).scrolltop();       console.log(offset);         if(offset > 497){           $("#fixedbar").animate({backgroundcolor: '#1b1b1b'}, 1000);           $("#fixedbar nav a").animate({color: '#fff'}, 1000);         }else{           $("#fixedbar").animate({backgroundcolor: '#fff'}, 1000);           $("nav a").animate({color: '#1b1b1b'}, 1000);          }       }     $(window).scroll(function() {        checkoffset();      });    });

if refresh page , past point indeed changes, if scroll past point doesn't change. how can fix this?

your script works.

but since animating on every scroll. there chance of having consecutive animation cycles.

possible solutions (any 1 of these points),

  1. to use either css method rather animate
  2. executing stop() before animating should help.
  3. check existing color value before executing animate method

to know more stop() in jquery.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
