I display a popup to ask confirmation of delete a record, the popup displays but with a "system message" like "the page at the address mywebsite show:" follows by my message "are you sure ....".
I want to display only my message 'Are you sure ?'Not the message 'the page at the address mywebsite show:' just above my message.
How can do this please ? Thank in advance.
<a href="php/Delete.php5?" onClick="return confirm('Are your sure ?');"><img src="images/Cancel16x16.png"></a>
