hi guys...
i have this finder javascript...currently it allows navigation through an unordered list...when a link is clicked it will show the entire path starting from the root link...
the way i want it work is that it should show only the child list on clicking and hide everything else...plz see if anyone can help me...this seems fairly easy but i'm not really good at javascript...
this is the relevant piece of javascript that i need to edit...
// loop through all links of inside finder
lis=document.getElementById('finder').getElementsByTagName('li');
for(i=0;i<lis.length;i++)
{
// if the li containing the link has no nested list, skip this one
if(!lis[i].getElementsByTagName('ul')[0])
{
continue;
}
var newa=document.createElement('a');
newa.href='#';
newa.appendChild(document.createTextNode(lis[i].firstChild.nodeValue));
lis[i].replaceChild(newa,lis[i].firstChild);
// otherwise apply the parent class
cssjs('add',newa,parentClass);
// if the user clicks on the link
lis[i].getElementsByTagName('a')[0].onclick=function()
{
// loop through all lists inside finder
for(var i=0;i<uls.length;i++)
{
// avoid the list connected to this link
var found=false;
for(j=0;j<uls[i].getElementsByTagName('ul').length;j++)
{
if(uls[i].getElementsByTagName('ul')[j] ==
this.parentNode.getElementsByTagName('ul')[0])
{
found=true;
break;
}
}
// and hide all others
if(!found)
{
cssjs('add',uls[i],hideClass)
cssjs('remove',uls[i],showClass)
cssjs('remove',uls[i].parentNode.getElementsByTagName('a')[0],openClass)
cssjs('add',uls[i].parentNode.getElementsByTagName('a')[0],parentClass)
}
}
// change the current link from parent to open
cssjs('swap',this,parentClass,openClass)
// show the current nested list
cssjs('add',this.parentNode.getElementsByTagName('ul')[0],showClass)
// don't follow the real HREF of the link
return false;
}
}
ive embedded the entire script in the webpage below...
thanks!
