setTimeout inside for loop [duplicate]

Answer 1

May be better to loop in cascade. For exemple to fade a div :

div=document.createElement('div');
div.style.opacity=1;
setTimeout(function(){fade(1);},3000);
function fade(op){
    op-=.05;
    if(op>0) setTimeout(function(){div.style.opacity=op;fade(op);},30);
    else document.body.removeChild(div);
}
