Menu
I am trying to create a collasible menu to control the navigation to my site. The site is controlled by a template. I found some javascript and got the menu working. The menu works good. But when you goto another page the state of the menu goes to default. I would like it to remeber the state of the menu when you goto another page. I figured a cookie would do this. I am just learning java so I am not sure how to go about doing this. So any help would be appreciated.
This is the java between the head tags
<script language=”JavaScript” type=”text/JavaScript”>
<!–
function exp_coll(ind)
{
s = document.getElementById(“sp_” + ind);
i = document.getElementById(“im
i2 = document.getElementById(“im2_” + ind);
if (s.style.display == ‘none’)
{
s.style.display = ‘block’;
i.src = “../test/images/minus.gif”;
i2.src = “../test/images/folder.gif”;
}
else if (s.style.display == ‘block’)
{
s.style.display = ‘none’;
i.src = “../test/images/plus.gif”;
i2.src = “../test/images/folder.gif”;
}
}
function exp(ind)
{
s = document.getElementById(“sp_” + ind);
i = document.getElementById(“im
i2 = document.getElementById(“im2_” + ind);
if (!(s && i && i2)) return false;
s.style.display = ‘block’;
i.src = “../test/images/minus.gif”;
i2.src = “../test/images/folder.gif”;
}
function coll(ind)
{
s = document.getElementById(“sp_” + ind);
i = document.getElementById(“im
i2 = document.getElementById(“im2_” + ind);
if (!(s && i && i2)) return false;
s.style.display = ‘none’;
i.src = “../test/images/plus.gif”;
i2.src = “../test/images/folder-open.gif”;
}
function coll_all()
{
coll(0);
coll(9);
coll(33);
coll(85);
coll(87);
}
function exp_all()
{
exp(0);
exp(9);
exp(33);
exp(85);
exp(87);
}
//–>
</script>
and this is in the body where the menu appears
