Create a nested UL menu based on the URL path structure of menu items

Question

I have an array of menu items, each containing Name and URL like this:

var menuItems = [  
    {  
        name : \"Store\",  
        url : \"/store\"  
          


        

Answer 1

12 simple lines of code:

var rootList = $("
").appendTo("body");
var elements = {};
$.each(menuItems, function() {
    var parent = elements[this.url.substr(0, this.url.lastIndexOf("/"))];
    var list = parent ? parent.next("ul") : rootList;
    if (!list.length) {
        list = $("
").insertAfter(parent);
    }
    var item = $("
").appendTo(list);
    $("").attr("href", this.url).text(this.name).appendTo(item);
    elements[this.url] = item;
});
