basicly whenever i invoke function with setTimeout within that function that i want to invoke , the setTimeOut works as setTimeout+setInterval ?
-
well , think i still dont get why it is invoking itself in intervals (setInterval is NOT there and setTimeout is just delaying invoke of function) i would understand it , if there was setInterval... but setTimeout which just delay invoke of the function..
-
http://jsfiddle.net/N2aP2/ i tried it here , so it seems it really works like (for)loop , but why is setTimeout behaving like setInterval?
-
so when there is increment in if statement it behaves like (for)loop?

yo, this code var i = 0;function swapImage() { var kk=document.getElementById("branka");kk.src=path[i];var mm=document.getElementById("vole");mm.setAttribute("href",change[i]); if(i < path.length - 1&& i<change.length-1){ i++;} else {i = 0;} setTimeout("swapImage()",3000); } window.onload=swapImage; is used for bad looking slide-show , but my question is , why is this function executed every 3s? it should be executed once (it check if i<array.length and if its true i goes up(i++))no? there isnt setInterval , so why is this function executed every 3s? there is only delay wth seTimeout , thanks for answer
