Avoid submenu from disappearing quickly
All,
How do I modify the javascript behind the following menu to make sure the menu items don't disappear so fast when they are no longer hovered? I want the submenus to wait for atleast 2 seconds on the screen before they disappear.

The Javascript behind the html looks like this:
var menu=function(){
var t=0,z=50,s=6,a;
function dd(n){this.n=n; this.h=[]; this.c=[]}
dd.prototype.init=function(p,c){
a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'),
l=s.length, i=0;
for(i;i<l;i++){
var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
h.onmouseover=new Function(this.n+'.st('+i+',true)');
h.onmouseout=new Function(this.n+'.st('+i+')');
}
}
dd.prototype.st=function(x,f){
var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
clearInterval(c.t); c.style.overflow='hidden';
if(f){
p.className+=' '+a;
if(!c.mh){c.style.display='block'; c.style.height='';
c.mh=c.offsetHeight; c.style.height=0}
if(c.mh==c.offsetHeight){c.style.overflow='visible'}
else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
}else{p.className=p.className.replace(a,'');
c.t=setInterval(function(){sl(c,-1)},t)}
}
function sl(c,f){
var h=c.offsetHeight;
if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
if(f==1){c.style.filter=''; c.style.opacity=1;
c.style.overflow='visible'}
clearInterval(c.t); return
}
var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
c.style.opacity=o; c.style.filter='alpha(op开发者_StackOverflowacity='+(o*100)+')';
c.style.height=h+(d*f)+'px'
}
return{dd:dd}
}();
setTimeout(
function(){
// here is you code for disappear menu
}, 2000);
You can use jQuery's delay function before hiding the menu.
I saw your code. You're using onmouseout event. Inside that event, you can wait for 2 seconds, then hiding the dropped down menu:
$('#menu').hover(function () {
// Mouse entered.
}, function () {
// Mouse left (out)
$(this).delay(2000).hide();
});
Sounds like a good candidate for hoverintent.
