change textfield with every keyup

I'm trying to fill three fields with the same text but I'm only writing into the first one. This code is only working once and then it isn't (the alert is working fine constantly).

$( 'textarea[name="posting"]' ).on( "keyup", function() {
 var text = $('textarea[name="posting"]').val();
    $('textarea[name="posting_twitter"]').replaceWith(text);
      alert(text)
});

Text area value can be replaced with val() 

  $('textarea[name="posting_twitter"]').val(text)

See the working jsfiddle:

JS:

$('#first').on('keyup', function() {
   $('#second').val($(this).val()); 
});

HTML:

<input id="first" type="text">
<input id="second" type="text">

output

All you need to do is use jQuery's .val() method, which can both set and get the value of an input element. Read the documentation.

Try this:

$( 'textarea[name="posting"]' ).on( "keyup", function() {

 var text = $('textarea[name="posting"]').val();
    $('textarea[name="posting_twitter"]').val(text);
      alert(text);

});
