javascript+css+xml 全选树

vs2005 的TreeView树控件入门非常简单,花费很少时间就可以构造一颗树形目录来,是新手的不错选择,但是它缺少灵活性,要改变它的图标除了它本身的模板外,就有点麻烦了,还有它的点击回发事件,特别烦。如果选择父节点同时选择子节点,就很麻烦了,因为它的结构是div+table的,我们要扩展它也要花不少时间。我发现很多高手都没有用到它,都是自己写的,这样可以灵活扩展,和修改相关属性,下面是我用javascript+css+xml写的一颗树,只要xml文件的格式不变,你可以随便增加、删除目录,很容易就可以得到相应的树目录了,你可以在原有的基础上扩展更多的属性、和相关的操作。当然刚刚写出来的东西不是很好,还有BUG,没有时间测试,如果大家有什么建议或发现bug请提出来。大家一起讨论。
