通过本文主要向大家介绍了jquery,easyui等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
网上答案说是因为Easy-ui在低版本时应将class样式删去，而在javascript里写url，因为class里有url的话javascript里也存在url，就会使页面刷新俩次，但是测试后没有解决我的问题，后来通过反复测试终于找到问题，
<ul id="eva" style=" font-size:25px; "> </ul>
因为在页面写了style,将style里的样式删去就可以解决问题了，现附上完整的ajax动态树和Grid表格代码。
