Question

I’m using $("#text").val() to get text from textarea field and send through ajax, but linebreaks (I mean \r\n in textarea) disappeares at all… Why could it be and how to prevent it?

Thanks!

Taken from the documentation for val():

Note: At present, using .val() on textarea elements strips carriage
return characters from the browser-reported value. When this value is
sent to the server via XHR however, carriage returns are preserved (or
added by browsers which do not include them in the raw value). A
workaround for this issue can be achieved using a valHook as follows:

$.valHooks.textarea = {
  get: function( elem ) {
      return elem.value.replace( /\r?\n/g, "\r\n" );
  } };

Adding the above snippet to your javascript will override the default behaviour of val() for textareas and will preserve whitespace.
