[Shantanu38]

I am trying to send custom message in alert box. It didnt worked in my application. below is code snippet.I have created variable .

$('#searchCriteria').areYouSure( { 'message' : userNavigateAwayMessage
});

Then i verified it on your sites, its not showing custom messages too.

For security reason this cannot be modified, this message is generated by the browser. I have not found any way to bypass this message using this script or similar script.

I hope there is a workaround on this or any way to bypass the security. :(
