Bind textbox to 'enter' key

I've made a chat system with AJAX and jQuery and there is no <form> tag wrapping the TextBox for chat messages, so I can't submit that message with the ENTER button on the keyboard.

Is there any way I can submit that value from TextBox with javascript?

Thanks.

document.getElementById("id_of_your_textbox").addEventListener("keydown", function(e) {
    if (!e) { var e = window.event; }
    e.preventDefault(); // sometimes useful

    // Enter is pressed
    if (e.keyCode == 13) { submitFunction(); }
}, false);
