easyui combotree的使用示例

一、View：

1、定义输入控件

<input id="ParentId" name="ParentId">

2、绑定combotree

$('#ParentId').combotree({
	url: "/Action/GetMenuTreeData/",
	method: "post",
	lines: true,
	required: true,
	onClick: function (node) {
　　　　　　　　　 //自动生成排序号
		$.post("/Action/GetMenuDisOrder/", { pId: node.id }, function (data) {
			$("#DisOrder").val(data);
		});
                //自动生成当前层级
		$.post("/Action/GetMenuDisLevel/", { pId: node.id }, function (data) {
			$("#DisLevel").val(data);
		});

	}
});

二、Controller:

[HttpPost]
public ActionResult GetMenuTreeData()
{
	//取从数据字典中取中Menu对应的ID号
	var dic = _dictionaryService.Single(o => o.Name == "MENU" && o.IsDeleted == false);
	var menuId = dic.Id;

	//查询所有菜单信息
	var menus = _actionService.Where(o => o.IsDeleted == false && o.OperationType == menuId && o.IsShow == true, o => o.DisOrder).ToList();

	//获取根结点信息
	RSCC.Model.TreeNode rootNode = _actionService.Single(o => o.ParentId == 0).ToNode();

	//3、根据根结点对应的ID，查询其所有的子节点
	rootNode.children = FillSonNodes(menus, rootNode.id);

	return Content("[" + operationContext.ToJson(rootNode) + "]");
}

/// <summary>
/// 递归生成子节点集合
/// </summary>
/// <param name="listPermission"></param>
/// <param name="parentId"></param>
/// <returns></returns>
List<RSCC.Model.TreeNode> FillSonNodes(List<RSCC.Model.Action> list, int parentId)
{
	List<RSCC.Model.TreeNode> sonNodes = null;

	//循环权限集合，查找子权限
	foreach (RSCC.Model.Action m in list)
	{
		//查找到子权限
		if (m.ParentId == parentId)
		{
			//实例化子节点集合
			if (sonNodes == null)
				sonNodes = new List<RSCC.Model.TreeNode>();

			//将子权限转成子节点
			RSCC.Model.TreeNode sonNode = m.ToNode();
			//将子节点加入子节点集合
			sonNodes.Add(sonNode);
			//递归为子节点查找子节点集合
			sonNode.children = FillSonNodes(list, sonNode.id);
		}
	}

	return sonNodes;
}
