javascript：替换linebreak

Question

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

Thanks in advance.

Answer 1

"\\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>");

Answer 2

theString.replace(/\n|\r/g, '<br />')
