str.replace(/<br>/g,'\r');

The code should work - with the /gflag, it should replace all <br>s. It's possible the problem is elsewhere.
代码应该可以工作 - 使用/g标志，它应该替换所有<br>s。问题可能出在其他地方。
Try this:
尝试这个：
str = str.replace(/<br>/g, '\n');
'\n'is probably more appropriate than \r- it should be globally recognized as a newline, while \risn't common on its own. On Firefox, for example, \risn't rendered as a newline.
'\n'可能比\r- 它应该被全球公认为换行符更合适，而\r它本身并不常见。例如，在 Firefox 上，\r它不会呈现为换行符。

Use :
用 ：
str.replace(/<br>/gi,'\r');
/g is only for the first match. /gi is for global replacement
/g 仅用于第一场比赛。/gi 用于全局替换
