How could I improve this code so that I didn't need to place all code inside initAll()?

I have some form handling stuff, and I want to refactor that to OOP. This is the first thing I need to be more sure about.

/* Handling forms with object oriented programming. */

/* Wait for the DOM the be ready. */
window.onload = initAll;

function initAll() {

    var FormValidator = { // {{{
        msg: document.forms['contact'].msg,

    }; // }}}

    /* Inserts 'value' into the textarea. */
    FormValidator.msg.value = 'Hello world, from JavaScript!';
/* vim:set foldmethod=marker foldmarker={{{,}}}: */
