javascript - Line break represented as "r" on Mac? - Stack Overflow

See fiddle: if you press Enter in the textarea on a recent Mac, the newline character appears to be represented by \r, which would be in direct contrast to the answers to this, this and this question and to Wikipedia. To summarise these links:

  • \r represents a line break on old Macs (OS 9 and before)
  • \n represents a line break on UNIX systems (OS X, Linux)
  • \r\n represents a line break on Windows.

When I press Enter in the JSFiddle, I get the following result (OS X 10.11.6):

textarea: \r

span: \n

This behaviour took a long time to figure out and seems illogical. What could be the underlying rationale?

  • 1 your fiddle looks at the wrong thing, try testing the .value of the textarea... – dandavis Commented Jul 31, 2016 at 21:39

Reset to default 11

I believe you're confusing two things:

  1. What character code does pressing the enter key yield?
  2. What line ending is used on which platforms?

As far as I know, the answer to #1 is 13 (ASCII carriage return, "\r") for all platforms.

Do you have a platform where this is not what you're seeing?
