line break in alert popup

I would suspect that you need to change your code to;

string msg = "Your session will expire in 10 minutes. \\n Please save your work to avoid this.";

And escape the \n otherwise your code outputted would actually include the line break rather than \n

Your output code would look like:

setTimeout('alert("Your Session....
Please save your work to ....");', 1000);

Rather than:

setTimeout('alert("Your Session....\n Please save your work to ....");', 1000);

PHP interprets backslashes literally when expressed in single quotes.

Instead, use doubles and the newline will be parsed and honoured.

php echo alert message with new line '\n' not working

Edit it to not change to newline in PHP, instead in javascript:

'No result found for the following info:\nName: '.$FullName.'\nIC: '.$ID.' in database.'
^ ^ ^ ^ ^ ^

OR by adding extra backslash: "\\n".

According to Panther, also truth: use 'alert("' . $message . '")'.
