Hello everyone,
I am working with Mod Harbour and have noticed that in my JavaScript code \\n causes a line break,
while \n leads to an error. Is this a known behavior in Mod Harbour, or could there be another reason for it?
Has anyone had similar experiences or can give me a tip on how to handle this?
Best regards,
Otto

Dear Otto,

Could you please provide a small code example to review it ?

thanks

Dear Antonio,
"\n" -> "\\n" OK

Here is my test code. If I change the line to:
keysString += key + ": " + value + "\\n";
it works fine.

If I run it with keysString += key + ": " + value + "\n"; in HTML, all works fine.

Best regards,
Otto

Dear Otto,
I think \n leads to an error because the backslash is an escape character in javascript.
according to chatgpt :-)

... when used in a string, the \ expects to be followed by another character to form the escape sequence.
So \\n is needed in this case I suppose.
kind regards

Dear Ruth,
the problem is that \n in JS works in a html file but not in a mod harblur prg file.

Please copy the HTML part into a HTML file and test.
Best regards,
Otto
