<h2>HoverTree基本彈出窗口</h2>

<div style="margin:20px 0;">
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="$('#hover'+'treewindow').window('open')">Open</a>
<a href="javascript:void(0)" class="easyui-linkbutton" onclick="$('#hovertreewindow').window('close')">Close</a>
</div>
<div id="hovertreewindow" class="easyui-window" title="HoverTree基本彈出窗口" data-options="iconCls:'icon-save'" style="width:500px;height:200px;padding:10px;">
這是彈出窗口的內容,使用EsayUI實現。本窗口可以改變大小，自由拖動，最大化，收起。<a href="http://hovertree.com" target="_blank" style="color:black;">HoverTree</a>
