JavaScript: Replace line break
Question by SimplyMe | 2012-02-12 at 19:18
I have a string in JavaScript and I would like to replace in this string all new lines with <br>. So far, I have developed the following approach:
str.replace("\n", "<br>");
For whatever reason, that does not seem to be working. What can be the reason?

Depending on the operating system, other characters can be used as a line break. On Windows, it is #13#10 (\r\n), Unix or Linux are only using #10 (\n) and macOS #13 (\r). So, if you have only replaced \n, for example, you will not get it work on Windows.
Try it with this solution:
This regular expression causes, that really all species of line breaks are replaced.
Besides, if you stay in your solution above, only the first occurrence of \n will be replaced. Here, it is also better, to use a regular expression:
The g at the end ensures that all occurrences are replaced.
