Yes: you need to add a tabindex attribute to the <div> to allow it to receive the focus.

<div id="idtext" tabindex="1"></div>

Also, the property you want for the character code of the text entered in a keypress event is which, not keyCode.

Finally, the HTML comment tags inside the <script> element are unnecessary in all modern browsers.
