I would like to add a delete confirmation to my form button 
Possible javascript to use??

```
<script type="text/javascript"> 
function confirmDelete() { 
return confirm("Are you sure you want to delete?");   
} 
</script> 

```

This is currently working inside my form.

```
<input type="button" onclick="parent.location='<?php echo "delete.php?id=" . $people['id'] ?>'" value='Delete'>

```

How can I integrate the javascript into the onclick event? Either using the above javascript or any other way that may be better
