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 <br> elements, insert raw text with new line character and then remove the <br> 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');

var str   document getElementById  mydiv   innerHTML  document getElementById  mytextarea   innerHTML   str replace   lt br s       gt  gi    n      or using jQuery   var str       mydiv   html    var regex     lt br s       gt  gi      mydiv   html str replace regex    n       example  edit  added i flag  edit2  you can use   lt br   gt    gt  gi which will match anything  between the br and slash if you have for example  lt br class  clear    gt

Not really anything to do with jQuery  but if you want to trim a pattern from a string  then use a regular expression    lt textarea id  ta0  gt  lt  textarea gt   lt button onclick     var ta   document getElementById  ta0      var text    some lt br gt text lt br   gt to lt br  gt replace     var re     lt br      gt  gi    ta value   text replace re    n      gt Add stuff to text area lt  button gt
