zTree是不错的树形工具,功能强大异常,不过因此也带来一些问题,使用复杂,体型庞大.
这是zTree的官方网站喜欢的朋友可以多加关注 http://www.baby666.cn/hunter/zTree.html
zTree有很完善的版主手册,对于老手来说很方便,不过例子里没有附带说明,对于新手立即使用上有些问题.这里我举个最简单例子,用于新手立即使用,以后遇到更多应用时我也会把例子贴上来.

把以上代码复制到html文件里就可以了,当然你必须把该导入的文件全部导入,至于这些文件去官网下就有了,至于数据内容就得自己想办法组成这样格式就行了,也可以用jquery异步请求json数据
php异步传输数据:
