等待中 急问 jsp中调用js中的一个函数 为什么参数传递不是本身的参数啊
jsp页面如下：
<%
  String id=(String)session.getAttribute("uid");
  StuInfDAO stuinfdao = new StuInfDAO(); 
  PageHelp pagehelp=null;
  List list = null;
  pagehelp=(PageHelp)request.getAttribute("pagehelp");
  if(pagehelp==null){
  //System.out.println("起始页");
  int currentPage=1;
  pagehelp =stuinfdao.queryInfo(" ",currentPage);
  }
list=pagehelp.getObjectlist();
 
  %>
   
  <form name="search" method="post" action="./servlet/ReinfServlet" target="_self" onSubmit="return docheck()">
<input type="hidden" name="opflag" value="search">
<table align="center" > 
  <tr>
  <td height="40" colspan="29" align="center"> <font size="5" face="华文楷体"><strong>学生信息</strong></font></td>
  </tr>
