一，简介
ligerTree的功能列表：
1,支持本地数据和服务器数据(配置data或者url)
2,支持原生html生成Tree
3,支持动态获取增加/修改/删除节点
4,支持大部分常见的事件
5,支持获取选中行等常见的接口方法
二，第一个例子
引入库文件
遵循LigerUI系列插件的设计原则(插件尽量单独)，ligerTree是一个单独的插件，也就是说只需要引入plugins/ligerTree.js和样式css文件就可以使用(当然必须先引入jQuery)，在这个例子中，我把tree用到的样式和图片分离了出来，有兴趣的朋友可以下载来看看
<script src="lib/jquery/jquery-1.3.2.min.js" type="text/javascript"></script>
<link href="lib/ligerUI/skins/Aqua/css/ligerui-tree.css" rel="stylesheet" type="text/css"/>
<script src="lib/ligerUI/js/plugins/ligerTree.js" type="text/javascript"></script>
加入HTML
<ul id="tree1">
<li>
<span>节点1</span>
<ul>
<li>
<span>节点1.1</span>
<ul>
<li><span>节点1.1.1</span></li>
<li><span>节点1.1.2</span></li>
</ul>
</li>
<li><span>节点1.2</span></li>
</ul>
</li>
</ul>
调用ligerTree
<table style="margin-top: 0px !important; margin-right: 0px !important; margin-bottom: 0px !important; margin-left: 0px !important; padding-top: 0px !important; padding-right: 0px !important; padding-bottom: 0px !important; padding-left: 0px !important; border-top-width: 0px !important; border-right-width: 0px !important; border-bottom-width: 0px !important; border-left-width: 0px !important; border-style: initial !important; border-color: initial !important; outline-width: 0px !important; outline-style: initial !important; outline-color: initial !important; background-image: none !important; background-attachment: initial !important; background-origin: initial !important; background-clip: initial !important; background-color: initial !important; text-align: left !important; float: none !important; vertical-align: baseline !important; position: static !important; left: auto !important; top: auto !important; right: auto !important; bottom: auto !important; height: auto !important; width: auto !important; font-family: Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace !important; font-weight: normal !important; font-style: normal !important; font-size: 1em !important; min-height: inherit !important; border-collapse: collapse !important; background-position: initial initial !important; background-repeat: initial initial !important; "><td style="font-size: 1em !important; margin-top: 0px !important; margin-right: 0px !important; margin-bottom: 0px !important; margin-left: 0px !important; padding-top: 0px !important; padding-right: 0px !important; padding-bottom: 0px !important; padding-left: 0.5em !important; border-top-width: 0px !important; border-right-width: 0px !important; border-bottom-width: 0px !important; border-left-width: initial !important; border-style: initial !important; border-color: initial !important; outline-width: 0px !important; outline-style: initial !important; outline-color: initial !important; background-image: none !important; background-attachment: initial !important; background-origin: initial !important; background-clip: initial !important; background-color: initial !important; text-align: left !important; float: none !important; vertical-align: top !important; position: static !important; left: auto !important; top: auto !important; right: auto !important; bottom: auto !important; height: auto !important; width: auto !important; font-family: Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace !important; font-weight: normal !important; font-style: normal !important; min-height: inherit !important; border-left-style: none !important; border-left-color: initial !important; color: rgb(0, 0, 0) !important; background-position: initial initial !important; background-repeat: initial initial !important; ">$("#tree1").ligerTree();
效果图
三，常用场景
场景一：不使用复选框：
$("#tree2").ligerTree({ checkbox: false });
场景二：不使用复习框和图标：
$("#tree3").ligerTree({ checkbox: false, parentIcon: null, childIcon: null });
效果如图：
append(parentNode, newdata)增加节点集合clear()清空collapseAll()全部节点都折叠demotion(treenode)降级为叶节点级别expandAll()全部节点都展开getChecked()获取选择的行(复选框)getData()获取树的数据源getParentTreeItem(treenode, level)获取父节点getSelected()获取选择的行hasChildren(treenode)是否包含子节点 loadData(node, url, param)加载数据remove(node)删除节点upgrade(treenode)升级为父节点级别
