Jquery replace not working over the entire input text
<p>I have a text box on a HTML page, the idea is that the user can enter any text into the box and then jquery will remove every other than letters of the alphabet.</p>

<p>This is what i have come up with, it works for small text samples, 1-2 lines, however anything over this it only works on a small section of the input text, is there a better way to do this?</p>

<pre><code>      $("#read").change(function () {
     read = $("#read").val().toLowerCase().replace(/[^a-z]+/, '');

      $("#read").val(read);

   });
</code></pre>
