javascript - Either toggling or remove class A and add class B on click with a delay -


i have jquery mobile page has jquery chat feature. type chat , few seconds later bot responds.

behind chat feature , filling whole page class has background image, , wish have when type text field , hit send background image class toggles class has different background image. wish have 2-3 second delay.

i have tried 

$(function () { $("#chatsend").click(function () {     $(this).parent(".tastetherainbow").toggleclass("ornot"); }); });

here jsfiddle...the background image not show there. https://jsfiddle.net/mattmega4/d9yodhtm/

one solution this: 

$(this).closest(".tastetherainbow").fadeto('fast', 0, function () {     $(this).toggleclass("ornot").fadeto('fast', 1); });

see demo: https://jsfiddle.net/d9yodhtm/3/

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.
