jQuery javascript regex Replace with \n

javascript jquery regex

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"));

edit: added i flag

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

javascript jquery regex

myString.replace(/ /g, "\n")

True jQuery way if you want to change directly the DOM without messing with inner HTML:

~~$('#text').find('br').prepend(document.createTextNode('\n')).remove();~~

Prepend inserts inside the element, before() is the method we need here:

$('#text').find('br').before(document.createTextNode('\n')).remove();

Code will find any elements, insert raw text with new line character and then remove the elements.

This should be faster if you work with long texts since there are no string operations here.

To display the new lines:

$('#text').css('white-space', 'pre-line');
