You need the  g for global matching  replace   n g    lt br   gt      This works for me for  n  - see this answer if you might have  r n  NOTE  The dupe is the most complete answer for any combination of  r n   r or  n   x000D   x000D  var messagetoSend   document getElementById  x   value replace   n g    lt br   gt     x000D  console log messagetoSend   x000D   lt textarea id  x  rows  9  gt  x000D      Line 1 x000D       x000D       x000D      Line 2 x000D       x000D       x000D       x000D       x000D      Line 3 x000D   lt  textarea gt  x000D   x000D   x000D    UPDATE  It seems some visitors of this question have text with the breaklines escaped as      some text r nover more than one line    In that case you need to escape the slashes   replace    r  n g    lt br   gt      NOTE  All browsers will ignore  r in a string when rendering

Use a regular expression for  replace      messagetoSend   messagetoSend replace   n g    lt br   gt       If those linebreaks were made by windows-encoding  you will also have to replace the carriage return   messagetoSend   messagetoSend replace   r n g    lt br   gt
