chat alarab, J V, Martin Honnen, Pat Friedl,
The following sets up a hierarchical collapsible list for IE5 (it could
be adapted for IE4 but I lack an IE4 installation currently to test it)
(The code does not work on IE4.0)and NN6 (or NN6 if marketing hype
prevails) by using HTML nested UL and
LI elements where the display style property is toggled between none
and block.
<HTML>
<HEAD>
<STYLE>
.expandable {
list-style-image:
url(http://msdn.microsoft.com/msdn-online/shared/graphics/plus.gif);
}
.leaf {
list-style-image:
url(http://msdn.microsoft.com//msdn-online/shared/graphics/solid.gif);
cursor: default;
}
.subList {
display: none;
}
</STYLE>
<SCRIPT>
function getSubList (li) {
var subList = null;
for (var c = 0; c < li.childNodes.length; c++)
if (li.childNodes[c].nodeName == 'UL') {
subList = li.childNodes[c];
break;
}
return subList;
}
function onClickHandler (evt) {
var target = evt ? evt.target : event.srcElement;
if (target.className == 'expandable') { //
if (target.expanded) {
target.style.listStyleImage =
'url(http://msdn.microsoft.com/msdn-online/shared/graphics/plus.gif)';
getSubList(target).style.display = 'none';
target.expanded = false;
}
else {
target.style.listStyleImage =
'url(http://msdn.microsoft.com/msdn-online/shared/graphics/minus.gif)';
getSubList(target).style.display = 'block';
target.expanded = true;
}
}
return true;
}
document.onclick = onClickHandler;
