1、引入相關資源

    <link href="zTree/zTreeStyle/zTreeStyle.css" rel="stylesheet" />
    <script src="../javascript/jquery-1.7.1.min.js"></script>
    <script src="zTree/jquery.ztree.core-3.5.min.js"></script>

2、設定頁面元素

<div class="zTreeDemoBackground left">
		<ul id="treeDemo" class="ztree"></ul>
	</div>
 

主要是為一個ul的class 屬性設定一個 ztree

3、主要API
主要屬性：id表示當前元素編號
pId表示父級元素編號
name表示要顯示的文字
open表示是否展示，設定為true顯示展開
isParent表示沒有子級時，也顯示為父級圖示
url表示點選轉到的超連結
target表示在哪個視窗開啟超連結
click表示單擊事件的處理
4、主要demo

 <script>
        var setting = {
            data: {
                simpleData: {
                    enable: true
                }
            }
        };

        var zNodes = [
			{ id: 1, pId: 0, name: "父節點1 - 展開", open: true },
			{ id: 11, pId: 1, name: "父節點11 - 摺疊" },
			{ id: 111, pId: 11, name: "葉子節點111" },
			{ id: 112, pId: 11, name: "葉子節點112" },
			{ id: 113, pId: 11, name: "葉子節點113" },
			{ id: 114, pId: 11, name: "葉子節點114" },
			{ id: 12, pId: 1, name: "父節點12 - 摺疊" },
			{ id: 121, pId: 12, name: "葉子節點121" },
			{ id: 122, pId: 12, name: "葉子節點122" },
			{ id: 123, pId: 12, name: "葉子節點123" },
			{ id: 124, pId: 12, name: "葉子節點124" },
			{ id: 13, pId: 1, name: "父節點13 - 沒有子節點", isParent: true },
			{ id: 2, pId: 0, name: "父節點2 - 摺疊" },
			{ id: 21, pId: 2, name: "父節點21 - 展開", open: true },
			{ id: 211, pId: 21, name: "葉子節點211" },
			{ id: 212, pId: 21, name: "葉子節點212" },
			{ id: 213, pId: 21, name: "葉子節點213" },
			{ id: 214, pId: 21, name: "葉子節點214" },
			{ id: 22, pId: 2, name: "父節點22 - 摺疊" },
			{ id: 221, pId: 22, name: "葉子節點221" },
			{ id: 222, pId: 22, name: "葉子節點222" },
			{ id: 223, pId: 22, name: "葉子節點223" },
			{ id: 224, pId: 22, name: "葉子節點224" },
			{ id: 23, pId: 2, name: "父節點23 - 摺疊" },
			{ id: 231, pId: 23, name: "葉子節點231" },
			{ id: 232, pId: 23, name: "葉子節點232" },
			{ id: 233, pId: 23, name: "葉子節點233" },
			{ id: 234, pId: 23, name: "葉子節點234" },
			{ id: 3, pId: 0, name: "父節點3 - 沒有子節點", isParent: true }
        ];

            $.fn.zTree.init($("#treeDemo"), setting, zNodes);
    </script>
 

最後通過init方法把所有資料載入進去，傳入引數setting,(ztree設定) ,zNodes(資料)
