Ztree可以去官网去下载相应的版本和API，我这里就简单的介绍下它的实现以及因为Ztree的小例子印发的Js问题，稍后我会在博客中写JS的异步问题，
我这里用的是MVC4.0,好了正文开始，上代码
namespace ZtreeDemo.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/ public ActionResult Index()
{
return View();
} public ActionResult Edit()
{
var list = GetData();
return Json(list, JsonRequestBehavior.AllowGet);
} [NonAction]
public List<Tree> GetData()
{
List<Tree> tree = new List<Tree>();
tree.Add(new Tree { id = 1, pId = 0, name = "蔬菜", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });
tree.Add(new Tree { id = 2, pId = 0, name = "动物", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });
tree.Add(new Tree { id = 3, pId = 0, name = "人类", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });
tree.Add(new Tree { id = 4, pId = 1, name = "茄子", icon = "../Script/css/zTreeStyle/img/diy/1_open.png" });
return tree;
} } public class Tree
{
public int id { get; set; }
public int pId { get; set; }
public string name { get; set; }
public string icon { get; set; }
}
}
这里我就不在解释了，类等我都没去规划，直接在这里写了，比较方便。接下来是视图代码，视图上我用的是ajax获取数据，
@{
Layout = null;
}

好了，这就是一个简单的树形菜单，我之前没用过Ztree,因为明天不用上班，就研究学习下，这只是个入门级的，有时间的话我会规整下Ztree返回Json对应数据格式的通用方法以及扩展Ztree的其他比较好的功能通用方法给大家，基本的效果如下：
