如何在ajax responsetext中添加换行符

Question

How to add a new line character in ajax responsetext. I have to return the Exception message containing error code and description which I have to then show using Javascript alert box.

PHP code snippet returning an error exception:

echo('Update Aborted\r\n'.$mIAPException->getErrorCode() . ': ' . $mIAPException->getFurtherDetails());

Javascript code snippet:

alert(client.responseText);

This is not working.

You need to use " -quoted strings. In ' -quoted strings, the \\r and \\n chars are nothing special.

echo "\n"; // spits out a newline
echo '\n'; // spits out a '\' char and an 'n' char
