You can use this to do it...
你可以用它来做...
str = str.replace(new RegExp(String.fromCharCode(13), 'g'), '\r\n');
Naturally, if you don't need to pass a variable to get the char code (or if it's not clearer), use the character in a regex literal, e.g. /\r/g.
当然，如果您不需要传递变量来获取字符代码（或者如果它不清晰），请在正则表达式文字中使用该字符，例如/\r/g.

ASCII code 13 is not a newline character, it is a carriage return which in many programming languages (including JavaScript) can be represented in strings with \r.
ASCII 码 13 不是换行符，它是一个回车符，在许多编程语言（包括 JavaScript）中可以用\r.
Here is how you can replace all occurences of \rin a string with \r\n:
以下是如何用 替换\r字符串中所有出现的\r\n：
str = str.replace(/\r/g, "\r\n");
