在fra中从框架页面移动到普通页面

Question

hey guys i was working on my college intranet login using php now i created a main page with three frames. this page will come after successful login. the page consists of 2 buttons namely submit and logout. if submit is chosen then based on radio button checked i will be directed to a new page. now my problem is if i click logout button the new page is loaded in the frame rather than full window. i want my new page to open in full window rather than the frame. is it possible??

here is my code:

<frameset rows="20%,80%">
<frame src="stheader.php" name="top" id="top" noresize="noresize">
<frameset cols="15%,85%">
<frame src="stmenu.php" name="bottomleft" id="bottomleft" noresize="noresize">
<frame src="staff2.php" name="bottomright" id="bottomright" noresize="noresize">
</frameset>
</frameset>

the top frame is nothing but an image file in it. the stmenu.php is:

    <h2><u>MENU</u></h2>
<h3><font color="green">Student Database</font></h3>
<ul>
<li><a href="stins.php" target="bottomright">Insert</a></li><br>
<li><a href="stdel.php" target="bottomright">Delete</a></li><br>
<li><a href="stup.php" target="bottomright">Update</a></li><br>
</ul>
    <button type="submit" formaction="staff1.php" target="bottomright" >Logout</button>

now based on this click of the above links, the new page opens in right bottom frame. now if say i click logout button then the page opens in right bottom frame rather than full page. i want it to open full page.

Answer 1

use javascript for the onclick event :

window.top.location.href = "http://www.site.com"; 

or use target attribute as _top

<a href="logout.php" target="_top">Log out</a>
