Question

How do i write a regex to replace <br /> or <br> with \n. I’m trying to move text from div to textarea, but don’t want <br>‘s to show in the textarea, so i want to replace then with \n.

Answer 1

var str = document.getElementById('mydiv').innerHTML;
document.getElementById('mytextarea').innerHTML = str.replace(/<br\s*[\/]?>/gi, "\n");

or using jQuery:

var str = $("#mydiv").html();
var regex = /<br\s*[\/]?>/gi;
$("#mydiv").html(str.replace(regex, "\n"));

example

edit: added i flag

edit2: you can use /<br[^>]*>/gi which will match anything between the br and slash if you have for example <br class="clear" />
