jQuery树形结构代码

本文分享一个jQuery实现的树状结构插件。它是一个轻量级的，易于扩展的插件，可以以树形结构显示列表，而且可以折叠和展开，支持多级。效果如下图：

Sample 1的源代码如下：

<script src="../lib/jquery.js" type="text/javascript"></script>
	<script src="../lib/jquery.cookie.js" type="text/javascript"></script>
	<script src="../jquery.treeview.js" type="text/javascript"></script>

<h4>Sample 1 - default</h4>
	<ul id="browser" class="filetree">
		<li><span class="folder">Folder 1</span>
			<ul>
				<li><span class="file">Item 1.1</span></li>
			</ul>
		</li>
		<li><span class="folder">Folder 2</span>
			<ul>
				<li><span class="folder">Subfolder 2.1</span>
					<ul id="folder21">
						<li><span class="file">File 2.1.1</span></li>
						<li><span class="file">File 2.1.2</span></li>
					</ul>
				</li>
				<li><span class="file">File 2.2</span></li>
			</ul>
		</li>

		<li class="closed"><span class="folder">Folder 3 (closed at start)</span>
			<ul>
				<li><span class="file">File 3.1</span></li>
			</ul>
		</li>
		<li><span class="file">File 4</span></li>
	</ul>
