Answer 1

request.getparameter ("trailName1"）肯定是可以获得的。
先排除两个可能的因素：
1.先将表格样式去除试一下：即只用
<input type="radio" name="trailName1" value="./dirdat/ss">
<input type="radio" name="trailName1" value="./dirdat/co">
<input type="radio" name="trailName1" value="./dirdat/bb">
然后用request.getparameter ("trailName1"）常识是否能够获取
2.改一下value的值试一下能否获取，即
<input type="radio" name="trailName1" value="1">
<input type="radio" name="trailName1" value="2">
<input type="radio" name="trailName1" value="3">

如果还不能获取，那就是其他原因，request.getparameter ("trailName1"）一定是可以用的，有成功用例。

Answer 2

你这样提交好像是取不到,你写一个JS,在JS 里面取到radio选中的值了，把值写到URL 里面，直接用URL提交

Answer 3

第一次听说form里的表单内容还要给JS才能提交，你先别用action，用servlet试试
