如何在javaScript中使用jsp代码中定义的变量？？？

[qiongni]

<%
int id=Integer.parseInt(request.getParameter("id"));
//String id=request.getParameter("id");
String query="select * from v_publish where id="+id;
ResultSet rs=dbBean.executeQuery(query);
String book_name="";
String book_type="";
if(rs.next())
{
book_name=rs.getString("book_name");
if(book_name==null) book_name="";
book_type=rs.getString("book_type");
if(book_type==null) book_type="";
} }
rs.close();
%>
<script language="javascript">
function InitForm(){
document.add.book_type.value=??; //想在这里用上面定义的book_type
}
</script>
求各位大侠予以指教！！！

} }
rs.close();
out.print("<script language='javascript'>function InitForm(){
document.add.book_type.value=" + book_type + ";}</script>
");
%>
具体调试一下，我没调试，调试好了，想在哪里调用，就跟直接写的函数一样调用

谢谢各位！问题终于解决！

[javafaq2004]

<script language="javascript">
function InitForm(){
document.add.book_type.value<%=book_type%>
}
</script>

<script language="javascript">
function InitForm(){
document.add.book_type.value=<%=book_type%>

楼上正解！

这样都不行，无法得到book_type值

那就是你写的有问题了
