JavaScript：If子句部分执行

Question

My problem is that when the condition is true it will close the window but not execute the php part !

here goes my code..

<script type="text/javascript">  
function onClose()  
{  
var r=confirm("Is the meeting Over!");  
if (r==true)
 {  
<?php $result=mysql_query($sql);?>  
window.close();  
 }  
else  
 {  
<?php $result2=mysql_query($sql2);?>    
 }  
}  
</script>  

this is the php part..

$sql="UPDATE previousmeetings SET Live='0' WHERE MeetingID='34'"; //$meeting_id  

$sql2="UPDATE previousmeetings SET Live='1' WHERE MeetingID='34'";

Answer 1

You are trying to execute PHP code inside a javascript block. PHP is server side, JS is client side so this wont work.

If you need to call a PHP script via JS you can use an AJAX call, a library such as jQuery or Prototype will make this easier.
