Cascading menu script

[Anthony]

Below is a script I found at http://javascript.internet.com/ for a
cascading menu. The script works great but there is one thing that I
would like modified. BecauseI am just learning javascript, I did not
want to try to modify the code without a little help. When you place
the mouse over the menu bar, this script calls the function to show the
menu. I would like it modified to hide the menu when the mouse is
removed. Please help. The full code is below:

function InitMenu()
{
var bar = menuBar.children

for(var i=0;i < bar.length;i++)
{
var menu=eval(bar.menu)
menu.style.visibility = "hidden"
bar.onmouseover = new Function("ShowMenu("+bar.id+")")
var Items = menu.children
for(var j=0; j<Items.length; j++)
{
var menuItem = eval(Items[j].id)

if(menuItem.menu != null)
{
menuItem.innerHTML += "<Span
Id="+menuItem.id+"_Arrow class='Arrow'>4</Span>"
//var tmp = eval(menuItem.id+"_Arrow")
// tmp.style.pixelLeft =
menu.getBoundingClientRect().Right //- tmp.offsetWidth - 15
FindSubMenu(menuItem.menu)}

if(menuItem.cmd != null)
{
menuItem.onclick = new
Function("Do("+menuItem.id+")") }

menuItem.onmouseover = new
Function("highlight("+Items[j].id+")")

}

}
}
function FindSubMenu(subMenu)
{
var menu=eval(subMenu)
var Items = menu.children
for(var j=0; j<Items.length; j++)
{
menu.style.visibility = "hidden"
var menuItem = eval(Items[j].id)


if(menuItem.menu!= null)
{
menuItem.innerHTML += "<Span
Id="+menuItem.id+"_Arrow class='Arrow'>4</Span>"
// var tmp = eval(menuItem.id+"_Arrow")
//tmp.style.pixelLeft = 35
//menuItem.getBoundingClientRect().right - tmp.offsetWidth - 15
FindSubMenu(menuItem.menu)
}

if(menuItem.cmd != null)
{
menuItem.onclick = new
Function("Do("+menuItem.id+")") }

menuItem.onmouseover = new
Function("highlight("+Items[j].id+")")

}
}
function ShowMenu(obj)
{
HideMenu(menuBar)
var menu = eval(obj.menu)
var bar = eval(obj.id)
bar.className="barOver"
menu.style.visibility = "visible"
menu.style.pixelTop = obj.getBoundingClientRect().top +
obj.offsetHeight + Bdy.scrollTop
menu.style.pixelLeft = obj.getBoundingClientRect().left +
Bdy.scrollLeft
}

function highlight(obj)
{
var PElement = eval(obj.parentElement.id)
if(PElement.hasChildNodes() == true)
{ var Elements = PElement.children
for(var i=0;i<Elements.length;i++)
{
TE = eval(Elements.id)
TE.className = "menuItem"
}
}
obj.className="ItemMouseOver"
window.defaultStatus = obj.title
ShowSubMenu(obj)
}

function Do(obj)
{
var cmd = eval(obj).cmd
window.navigate(cmd)

}

function HideMenu(obj)
{
if(obj.hasChildNodes()==true)
{
var child = obj.children

for(var j =0;j<child.length;j++)
{
if (child[j].className=="barOver")
{var bar = eval(child[j].id)
bar.className="Bar"}

if(child[j].menu != null)
{
var childMenu = eval(child[j].menu)
if(childMenu.hasChildNodes()==true)
HideMenu(childMenu)

childMenu.style.visibility = "hidden"
}
}

}
}
function ShowSubMenu(obj)
{
PMenu = eval(obj.parentElement.id)
HideMenu(PMenu)
if(obj.menu != null)
{
var menu = eval(obj.menu)
menu.style.visibility = "visible"
menu.style.pixelTop = obj.getBoundingClientRect().top +
Bdy.scrollTop
menu.style.pixelLeft = obj.getBoundingClientRect().right +
Bdy.scrollLeft
if(menu.getBoundingClientRect().right > window.screen.availWidth )
menu.style.pixelLeft = obj.getBoundingClientRect().left -
menu.offsetWidth
}
}
