在上篇文章给大家介绍了jquery中EasyUI实现异步树，本文给大家介绍jquery easyui实现动态树。
首先是在jsp页面中引入相关的js文件
在body中加入流程列表，通过后天拼接json数据
具体内容请看下面代码详情吧。
首选在jsp页面中引入相关的js
<link rel="stylesheet" type="text/css" href="<%=path %>/css/jquery_easyui/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="<%=path %>/css/jquery_easyui/themes/icon.css">
<script type="text/javascript" src="<%=path %>/js/jquery_easyui/jquery-1.4.4.min.js"></script>
<script type="text/javascript" src="<%=path %>/js/jquery_easyui/jquery.easyui.min.js"></script>添加script
<script>
$(function(){
$('#tt2').tree({
checkbox: false,
url: '<%=path%>/formconfig/loadWfNodes.do',
onBeforeExpand: function(node){
$('#tt2').tree('options').url = '<%=path%>/formconfig/loadWfNodes.do?wfId='+node.id;
}
});
});
</script>在body中加入
<body>
<ul id="tt2">
<li state="closed" id='0'><span>流程列表</span></li>
</ul>
</body>后台拼接json数据
