Google Apps脚本replaceText正则表达式出现问题

Question

So in my code

body.replaceText("test1","test2");

works and so do simple regexs, but I can't get more complex ones to work. For example I want to remove all spacing between two tags and replace it with three carriage returns. I've tested it out in regexr and other tools and it works but it does nothing in my Apps Script.

 body.replaceText("/</em>[\r\n]+<strong>/g","</em>\r\r\r<strong>");

this doesn't work either

body.replaceText("</em>[\r\n]+<strong>","</em>\r\r\r<strong>");

Answer 1

我尝试了这个，对我有用

body.replaceText("</em>\\[\\\\r\\\\n\\]\\+<strong>", '</em>\r\r\r<strong>');
