How To Replace \n With In JavaScript?

I have a textarea where I insert \n when user presses enter. Code from this textarea is sent to a WCF service via jQuery.ajax(). I cannot save \n in DB as it won't show in other ap

Solution 1:

Replace with global scope

$('#input').val().replace(/\n/g, "<br />")

or

$('#input').val().replace("\n", "<br />", "g")

Solution 2:

it could be done like this:

$('textarea').val().replace(/\n/g, "<br />");

edit: sorry ... the regular expressions in javascript should not be quoted

working example

Solution 3:

Like said in comments and other answer, it's better to do it on server side.

However if you want to know how to do it on clientside this is one easy fix:

textareaContent.replace(/\\n/g, "<br />");

Where textareaContent is the variable with the data in the textarea.

Edit: Changed so that it replaces globally and not only first match.
