Hi everybody, I am using framesets which has got a TOP Frame and Bottom Frame. I have <form> in the bottom form. After submitting the Form, I am redirecting to a HTML page which I want to open in a main window (Parent / no framesets) and not in the bottom window and also not in a new page. How to proceed on with JSP. SUggestions or Piece of code is always welcome.

1. <form .... target="_top">

2. For Netscape browsers only:
response.addHeader("Window-target", "_top");

3. Use a client-side Javascript instead of redirect:
out.println("<script language=\"javascript\">");
out.println("top.location.href = \"page.htm\";");
out.println("</script>");

1.Assume this to be your bottom frame.
2.Add this script
     <script language="JavaScript">
       function calme()
       {
     window.open("http://www.prabooo.com","_parent");
       }
     </script>
3.From the submit button call the script
  <form>
  <input type="button" onClick="calme()">
  </form>
4.this redirects to the url and opens in the whole window.
Hope this would hlp u.

2praburamalingam: Is the piece of Javascript code better than <form ... target="_top">? :o)

Hi

I find "<form target=_top>" itself enough for my work.

But I don't understand ur js

"-------------
2For Netscape browsers only:
response.addHeader("Window-target", "_top");

3. Use a client-side Javascript instead of redirect:
out.println("<script language=\"javascript\">");
out.println("top.location.href = \"page.htm\";");
out.println("</script>");
 "------------
Can I know the use of this code?

cheers

The solution (2) will work with Netscape browsers only. You should send the additional HTTP header before redirect (in JSP, assume response is a com.caucho.server.http.Response, for example):
<%
response.addHeader("Window-target", "_top");
response.sendRedirect("http://www.server.com/some_page.jsp");
%>

The solution (3) is a _client-side_ javascript. Simply replace the
<%
response.sendRedirect("http://www.server.com/some_page.jsp");
%>
line with
<%
out.println("<script language=\"javascript\">");
out.println("top.location.href = \"http://www.server.com/some_page.jsp\";");
out.println("</script>");
%>
in your JSP page.
