How are <pre> whitespace and line return "saved"?

Question

If you want to toy with white-spaces, tabs, linefeed and carriage-return, how do you "select them" in javascript?

  x = $('pre').html().replace(/(\r\n|\n|\r)/gm, "#");

edit : ^Does not work for linefeed and carriage-return.

Now, tabs are /(\t)/ and spaces are /( )/.

Answer 1

Your example actually works.
