"\n"is chr(10). I think you want "\r":
"\n"是 chr(10)。我想你想要"\r"：
mystring.replace("\r", "<br>");
Updated: To replace ALL \r use a regular expression:
更新：要替换 ALL \r 使用正则表达式：
mystring.replace(/\r/g, "<br>");
If you want it to work with Windows, Unix and Mac style line breaks use this:
如果您希望它与 Windows、Unix 和 Mac 样式的换行符一起使用，请使用以下命令：
mystring.replace(/\r?\n|\r/g, "<br>");
