MVC 中使用TreeView

标签：

为了灵活性，本例中实现是在View中完成递归逻辑，因此可以在递归过程中控制样式，内容的render

也可以选择在后端完成递归逻辑返回partial 然后在前端jquery中加class

2. 将以下3个文件copy到项目中，如下所示：

3. 准备view model

public class JqTreeViewNode
    {
        public string Name { get; set; }
        public IList<JqTreeViewNode> Children { get; set; }


        public JqTreeViewNode()
        {
            Children = new List<JqTreeViewNode>();
        }
        public static JqTreeViewNode CreateTest()
        {
            return new JqTreeViewNode()
            {
                Name = "Root",
                Children = new List<JqTreeViewNode>()
                {
                    new JqTreeViewNode()
                    {
                        Name = "ChildLvl1-1",
                        Children = new List<JqTreeViewNode>
                        {
                            new JqTreeViewNode()
                            {
                                Name = "ChildLvl2-1",
                                Children = new List<JqTreeViewNode>()
                                {
                                    new JqTreeViewNode()
                                    {
                                        Name = "ChildLvl3-1",
                                    },
                                    new JqTreeViewNode(){Name = "ChildLv3-2"},
                                    new JqTreeViewNode(){Name = "ChildLv3-3"}
                                }
                            },
                            new JqTreeViewNode(){Name = "ChildLv2-2"}
                        }
                    },
                    new JqTreeViewNode(){Name = "ChildLv1-2"}
                }
            };
        }
    }

public ActionResult Index()
        {


            return View(JqTreeViewNode.CreateTest());
        }

@model WebApplication1.Controllers.JqTreeViewNode
