迷茫了 迷茫了， 用复选框删除数据怎么也也删不掉了，求教大神。
本来是想用JS结合做出一个选中然后删除的效果， 但删除总是实现不了， 无法获得选择的ID啊， 怎么办。求教了。

[解决办法]
对于复选框，应该按这种方式去取值吧：
if (obj.options[i].selected) {
arrSelValue[j] = obj.options[i].value;
arrSelText[j] = obj.options[i].text;
}
[解决办法]
先把你的表单提交方式改为post,再去测试下看传过去了没，没出问题就用request.getparameter("id");取到id就可以，这个不难啊。。。
[解决办法]
String[] deletes=request.getParameterValues(复选框的name);
for(int i=0;i<deletes.length;i++){
String sql="......where id="+deletes[i];
.......
运行sql语句
.......
}
类似这样试试
