Well, first of all:
1. Allthough AJAX is a nice buzzword, this has nothing to do with
(a)synchronous calls with javascript to the server.
2. Are you absolutely sure you want to rely on javascript for this? In some
browsers/for some users it will simply not work.
3. This should actually be in comp.lang.javascript
But here you go:
What I'd do, is have the buttons in the SAME form. Either that, or
duplicate the selection list if you want a sturdy application.
junk.php
<?php
if(isset($_POST['B']||isset($_POST['A'])){
if(isset($_POST['B'])) echo 'You choose to open this a new window, but
this is not possible without javascript enabled';
$val = $_POST['theList'];
echo "A0=" . $val . "<br>";
}
?>
<script type="text/javascript">
function form_new_window(button){
var form = button.form;
form.action = './junk2.php';
form.method = 'GET'; //or keep it a post
form.target = '_blank'; //new window
return true; //just to make sure.
}
</script>
<form action="./junk.php" method="POST" target="_self">
<select name="theList">
<option value="First'">First </option>
<option value="Second'">Second </option>
</select>
<input type="submit" value="Same window" name="A">
<input type="submit" value="New window" name="B"
onclick="form_new_window(this)">
</form>
