It has some old selectors. I just had to update it for a project
myself. There were just 4 lines that I changed, which got it to work
for my situation. There may be other issues for more complex trees; I
just had a two-level tree hierarchy.
- var branches = $("li[>ul]", this);
+ var branches = $("li:has(>ul)", this);
- $("li[ul]:not([>a])>span", this).click(function(event) {
+ $("li:has(>ul):not(>a)>span", this).click(function(event) {
- branches.filter("[>ul:hidden]")
+ branches.filter(":has(>ul:hidden)")
- branches.not("[>ul:hidden]")
+ branches.not(":has(>ul:hidden)")
