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。

    </html>想用复选框获得选中的ID 然后传到 deletearticle.jsp中， 在数据库中删除
    但苦于没有获得articleid的方法， 怎么办，求教。
    Ps: 两个页面都是独立，不存在打不开页面的，大神们可以先复制到自己的工程上先看一下效果，真心求教，一下午也没憋出来啊，谢谢谢谢~
      

  2.   

    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;
    }
      

  3.   

    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
      

  4.   

    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
