简单Ztree的实现————不连接数据库版

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;
}

<!DOCTYPE html>

<html>

<head>
<title>ZTREE DEMO - Custom Icon </title>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<link href="~/Script/css/demo.css" rel="stylesheet" />
<link href="~/Script/css/zTreeStyle/zTreeStyle.css" rel="stylesheet" />
<script src="~/Script/jquery-1.4.4.min.js"></script>
<script src="~/Script/jquery.ztree.core-3.5.js"></script>
<script type="text/javascript">
var tree;
$(function () {
$.ajax({
type: "Get",
url: "@Url.Action("Edit","Home")",
//async: false,
success: function (data) {
tree = data;
$.fn.zTree.init($("#treeDemo"), setting, tree);
}
});
})

var setting = {
data: {
simpleData: {
enable: true
}
}
};
//var zNodes = [
//    { id: 1, pId: 0, name: "展开、折叠 自定义图标不同", open: false, iconOpen: "../Script/css/zTreeStyle/img/diy/1_open.png", iconClose: "../Script/css/zTreeStyle/img/diy/1_close.png" },
//    { id: 11, pId: 1, name: "叶子节点1", icon: "../Script/css/zTreeStyle/img/diy/2.png" },
//    { id: 12, pId: 1, name: "叶子节点2", icon: "../Script/css/zTreeStyle/img/diy/3.png" },
//    { id: 13, pId: 1, name: "叶子节点3", icon: "../Script/css/zTreeStyle/img/diy/5.png" },
//    { id: 2, pId: 0, name: "展开、折叠 自定义图标相同", open: true, icon: "../Script/css/zTreeStyle/img/diy/4.png" },
//    { id: 21, pId: 2, name: "叶子节点1", icon: "../Script/css/zTreeStyle/img/diy/6.png" },
//    { id: 22, pId: 2, name: "叶子节点2", icon: "../Script/css/zTreeStyle/img/diy/7.png" },
//    { id: 23, pId: 2, name: "叶子节点3", icon: "../Script/css/zTreeStyle/img/diy/8.png" },
//    { id: 3, pId: 0, name: "不使用自定义图标", open: true },
//    { id: 31, pId: 3, name: "叶子节点1" },
//    { id: 32, pId: 3, name: "叶子节点2" },
//    { id: 33, pId: 3, name: "叶子节点3" }

//];

//$(document).ready(function () {
//    $.fn.zTree.init($("#treeDemo"), setting, Data);
//});

</script>

　　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：
