js动态拼接标签，样式丢失的解决方法

参考：http://blog.youkuaiyun.com/u010552788/article/details/49363107

今天使用jquery的append()方法来拼接，发现拼接的元素引用的easyui样式丢失。原因是easyui只在最初页面加载的时候进行一次性渲染。

想要的效果：

之前的效果：

起作用的代码：

var tagobj = $('#append');
$.parser.parse(tagobj);

页面相关代码：

<fieldset class="fieldset_jy">
                    <legend class="legend_jy">气瓶信息</legend>
