PHP JavaScript：PopUp窗口

Question

I have a table which echos a button, currently this button takes you to the 'details.php' with £booking_id record taken over to the new php scrpit. Here is my current code:

echo '<td>a href="Details.php?id='.$row['booking_id'].'"><button>View Details</button></td>';

I would like this button to open a new popup window. How do i merge the two together, so when i click the button the popup window and takes the 'booking_id' record over. i have the java script code:

<script type="text/javascript">
// Popup window code
function newPopup(url) {
    popupWindow = window.open(
        url,'popUpWindow','height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes')
}
</script>
<a href="JavaScript:newPopup('Details.php);">View Details</a>

echo '<td>';
echo '<input type="button" value="View Details" onclick="JavaScript:newPopup(\'Details.php?id='.$row['booking_id'].'\')" />';
echo '</td>';
