我的想法是，点击重庆就会隐藏或显示铜梁和奉节这两行数据，现在的设计只能隐藏和显示铜梁这一行的数据。原本打算用document.getElementsByName，然后再遍历设置style属性，但是<tr>没有name属性，而且真正的项目中会有很多个市及其下的县，即使能加上name属性也不好实现，因为要求点不同的城市只能隐藏或显示对应的县的数据,自然name属性也会有很多个，这样js就需要判断（感觉太繁琐了，这样下去），我该怎么做呢

[解决办法]
以上是根据中文来定位需要隐藏的行，最好给每行加上一个ID列用ID列的值来过滤而不是通过innerText的中文来过滤

哦, 那里的td里面要加上,  colspan="7"
还有就是, 样式你要重新设置下,
------解决方案--------------------  
tr  css: display:none
[解决办法]
可以在functions（this）这个试试，可以通过this。getpartentNote来操作当前所选的tr对象
