javascript - Firefox event firing issue -


i have list in markup connected event listener, each li contains 1 or 2 divs , idea stuff depending on div clicked. html sample:

<ul id="list">     <li><div class="first a"></div><div class="second b c"></div></li>     <li><div class="first f"></div></li>     <li><div class="first e"></div><div class="second d r"></div></li> …

js sample:

var currentlang = 'en'; var failcounter = 0; var currentarg = args[math.floor(math.random() * args.length)]; var previousargs = [];  function keyclicked(event) {     if (event.target.classname.split(' ').indexof(currentarg) > -1) {         textbox.style.opacity = 0;         settimeout(function () {             textbox.innerhtml = wonmessages[currentlang];             textbox.style.opacity = 1;             wrapper.classname = 'alert alert-success wrapper-active';         }, 250);         wrapper.onclick = function () { location.href = "…" };         list.removeeventlistener('click', keyclicked);     }     else {         if (failcounter < 1) {             failcounter++;             previousargs.push(currentarg);             { currentarg = args[math.floor(math.random() * args.length)]; }             while (previousargs.indexof(currentarg) > -1);             textbox.style.opacity = 0;             settimeout(function () {                 textbox.innerhtml = wrongmessages[currentlang];                 textbox.style.opacity = 1;                 wrapper.classname = 'alert alert-warning';             }, 250);         }         else {             textbox.style.opacity = 0;             settimeout(function () {                 textbox.innerhtml = lostmessages[currentlang];                 textbox.style.opacity = 1;                 wrapper.classname = 'alert alert-danger';             }, 250);                            list.removeeventlistener('click', keyclicked);         }     } } list.addeventlistener('click', keyclicked);

the problem while works fine in ie , chrome, firefox reason doesn't fire event when div of class first (the first 1 or 1 in li if li contains 1 div) clicked. firefox recognizes clicks on divs of class second. ideas, why? difference between browser leads that?

if may helpful — i've found solution. problem lied in css. divs should trigger event had negative z-index setting in :active state. turned out reason firefox refuses trigger events elements negative z-index.

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.
