In the code below I get the values from checkbox and onClicking the checkbox and delete/modify I want to send the values of the checkbox and the type of the button to servlet. How to do that?

<html>
<head>
<%String user=request.getParameter("Users"); %>
<script type="text/javascript">
var chk_val="";
	function get_check_value(chkbox){
    	if(chkbox.checked){
    		alert(chkbox.value);
    		var checked_value=chkbox.value;
    		
    	    document.list.name.value="AddUserServlet?type=delete&name="+checked_value;//This line is not working
    		
   	}
       
}
	
 function doDelete(theClick){        
      var type=theClick;
      alert(type);
      alert(checked_value);  
      chk_val=chkbox.value;
      alert(chk_val);	
	 
	
   }	
	
</script>
</head>
<body>
<center>

<%

String User[]=user.trim().split(" ");

for(int i=0;i<User.length;i++){
	
    out.println("<form name='list'>");
    out.println("<input type='checkbox' name='user" + i + "' value='"+ User[i] + "' onClick='return get_check_value(this)'>" + User[i] + "</input>");	
	out.println("</form>");
}
 
 %>

<form method="Post" name="add">
<input type="submit" value="ADD" onclick="return doSubmit(this)">
<input type="submit" value="MODIFY" onClick="return doDelete(value)">
<input type="submit" value="DELETE" onClick="return doDelete(value)">
</form>
</center>
</body>
</html>

Can't you use getParamterValues at server end, that seems to be earier.
