The code is as follows:

function check(){

   var radio = document.getElementsByName("xingbie");
   var checkbox = document.getElementsByName("hobby");
   var select = document.getElementById("opt");

   //获取select标签
   var index = select.selectedIndex;
   var text = select.options[index].text;
   var value = select.options[index].value;

   //获取radio标签
   for(var i=0;i    if(xingbie.item(i).checked){
     var val = xingbie.item(i).getAttribute("value");
     break;
    }
    continue;
   }
   //获取checkbox标签
   for(var i=0;i    if(hobbys[i].checked){
     alert(hobbys[i].value);
    }
    continue;
   }

   //提交form表单
   document.formkk.submit();

   
  }

Java：

复制代码 代码如下:

 String[] hobbys = request.getParameterValues("hobby");  //checkbox
 String text = request.getParameter("text");    //text
 String password = request.getParameter("password"); //password
 String xingbie = request.getParameter("xingbie");  //radio
 request.getParameter("hidden");
 request.getParameter("opt");    //select
