javascript - Unexpected behavior with class added by jQuery -


a tale of 2 fiddles (please use run button after jsfiddle pages load clearer idea of happeneing).

the first fiddle

dead simple:

$("body").addclass("noscroll"); alert($("body").hasclass("noscroll")); $("body").removeclass("noscroll"); alert($("body").hasclass("noscroll"));

with css:

.noscroll {     background-color: pink;     position: fixed;     width: 100%;     top: 200px; }

we have class. class added body, changing body's appearance/behavior. class removed body , body reverts default. working expected.

the second fiddle

$("body").addclass("noscroll"); alert($("body").hasclass("noscroll")); $(".noscroll").css({     "background-color" : "pink",     "position"  : "fixed",     "width"     : "100%",     "top"       : "200px" }); $("body").removeclass("noscroll"); alert($("body").hasclass("noscroll"));

no accompanying css time, it's added jquery, otherwise pretty similar above. working point. css applied, isn't removed. why happening?

thanks!

for second fiddle, when call css() on noscroll selector, applies styles inline element class noscroll. however, styles not preserved in named css style.

so code working. adding class noscroll, no styles affiliated class in css. also, removing class, styles css() call stay because applied inline.

to better idea, see fiddle inline style removed manually @ end.

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.
