javascript: replace linebreak

Question

I'm having a string which contains a chr(13) as linebreak. How can i replace it with eg.  ? I tried mystring.replace("\n"," "); but it didn't work

Thanks in advance.

Wouldn't it be simpler to assign the line break to a variable? — user1434364

"\n" is chr(10). I think you want "\r":

mystring.replace("\r", "<br>");

Updated: To replace ALL \r use a regular expression:

mystring.replace(/\r/g, "<br>");

If you want it to work with Windows, Unix and Mac style line breaks use this:

mystring.replace(/\r?\n|\r/g, "<br>");

Yep, chr(13) is '\r', not '\n'.

good news - it worked. but unfortunately only for the first linebreak (there's several in my string). any ideas?

you need to use the g flag in a regexp like in my answer, and not only take into account \r but \n too

Of course if you know the character code, you can always just use mystring.replace(String.fromCharCode(13), " ");

I like the third one above, nice solution. Is it not standard though to use instead of ? I could be wrong.
