How can I change the name of an input element with jQuery?

Question

I know I can target an input element with a specific name, for example

$("textarea[name=form_textarea]").val();

However I can't seem to find any examples of how I could go about changing the name itself, is this possible?

Answer 1

$("textarea[name=form_textarea]").attr("name", "new_name");

$("textarea").val("Name is: " + $("textarea").attr("name"));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea name="form_textarea"></textarea>
