Menu
first off the problem is that i have a 1 layer horizontal drop down menu. every time i click into a page from the sub menu it disappears which makes navigation hard for users. Im looking for help with the javascript below to help the menu stay up when navigating through the section of sub menus. and change accordingly when the sub menu is changed and help with this will be greatly appreciated.
var mastertabvar=new Object()
mastertabvar.baseopacity=0
mastertabvar.browserdetect=””
function showsubmenu(masterid, id){
if (typeof highlighting!=”undefined”)
clearInterval(highlighting)
submenuobject=document.getElementById(id)
mastertabvar.browserdetect=submenuobject.filters? “ie” : typeof submenuobject.style.MozOpacity==”string”? “mozilla” : “”
hidesubmenus(mastertabvar[masterid])
submenuobject.style.display=”block”
instantset(mastertabvar.baseopacity)
highlighting=setInterval(“gradualfade(submenuobject)”,50)
}
function hidesubmenus(submenuarray){
for (var i=0; i<submenuarray.length; i++)
document.getElementById(submenuarray[i]).style.display=”none”
}
function instantset(degree){
if (mastertabvar.browserdetect==”mozilla”)
submenuobject.style.MozOpacity=degree/100
else if (mastertabvar.browserdetect==”ie”)
submenuobject.filters.alpha.opacity=degree
}
function gradualfade(cur2){
if (mastertabvar.browserdetect==”mozilla” && cur2.style.MozOpacity<1)
cur2.style.MozOpacity=Math.min(parseFloat(cur2.style.MozOpacity)+0.1, 0.99)
else if (mastertabvar.browserdetect==”ie” && cur2.filters.alpha.opacity<100)
cur2.filters.alpha.opacity+=10
else if (typeof highlighting!=”undefined”) //fading animation over
clearInterval(highlighting)
}
function initalizetab(tabid){
mastertabvar[tabid]=new Array()
var menuitems=document.getElementById(tabid).getElementsByTagName(“li”)
for (var i=0; i<menuitems.length; i++){
if (menuitems[i].getAttribute(“rel”)){
menuitems[i].setAttribute(“rev”, tabid) //associate this submenu with main tab
mastertabvar[tabid][mastertabvar[tabid].length]=menuitems[i].getAttribute(“rel”) //store ids of submenus of tab menu
if (menuitems[i].className==”selected”)
showsubmenu(tabid, menuitems[i].getAttribute(“rel”))
menuitems[i].getElementsByTagName(“a”)[0].onmouseover=function(){
showsubmenu(this.parentNode.getAttribute(“rev”), this.parentNode.getAttribute(“rel”))
}
}
}
}
