is there a code to open a new window and close the old in one click?

ok so its as the title says

is there a way to open a new window and close the old one?

ok so ill explain a little more on what i want to achieve

i have 2 pages

  index.php

  page1.php

on the index.php page i have a dropdown box with 3 options

<select>
<option>--Choose--</option>
<option onclick="window.open('index.php')">Index</option>
<option onclick="window.open('page1.php')">Page 1</option>
</select>

ok so the dropdown box is doing what i would like by opening a new window but i would like to close the old one.

at the moment this is whats happening

the user is viewing "index.php" he clicks on the dropdown and selects "Page 1" this opens a new window displaying the content of page1.php but the index.php page is still open.

this is what i would like to happen

the user is viewing "index.php" he clicks on the dropdown and selects "Page 1" this opens a new window displaying the content of page1.php and also closes index.php.

is this possible??

i just cant get it to work... i have seen it done before but cant find the website that i saw it on

i have tried using onclick, onchange ect ect

if anyone could help me with this that would be great

could try something like

<option onclick="window.open('page1.php'); window.close('index.php')">Page 1</option>

could try something like

<option onclick="window.open('page1.php'); window.close('index.php')">Page 1</option>

thanks for your input Fugix

i have just tried that and it didnt work

i have found a different way to do this

my whole reason for the code above was because index.php has 3 frames on there and whenever i clicked a link it just opened in that frame and left the rest showing the content from index.php

i never thought to use parent.top or target="_top"

here is the code i have used and have got working

<select>
<option>--Choose--</option>
<option onclick=parent.top.location="index.php">Index</option>
<option onclick=parent.top.location="page1.php">Page 1</option>
</select>

this gets rid of the frames on the index page and loads page1.php in the full view
