...With a twist!

Hey guys, and thanks for looking.

I have a combobox, such as this:
<form>
<select size=10>
<option>
<option>
<option>
<option>
<option>
</select>
<input type=submit>
</form>

I am also using JS to bring focus to this element on page load. My goal is to have keyboard-only based control. Is there anyway I can submit the form when the user presses enter, while the focus is still in the select box.

I understand they can use TAB then press enter, but I'd like to avoid that.

Thanks for all of your help,

Devin

Something like this would work:

function onEnter(e){
    var keynum;
    
    if(window.event){
        // IE
        keynum = e.keyCode;
    }elseif(e.which){
        // Gecko & Opera
        keynum = e.which;
    }
    
    if (keynum == 13){
        // 13 = return
        document.form_name.submit();
    }
}

<select onkeypress="onEnter(event);">

Thank you very much! I really appreciate the help. My final code looks like this for anyone searching for a solution:

<script>
function onEnter(e){
var keynum;

if(window.event){
// IE
keynum = e.keyCode;
}elseif(e.which){
// Gecko & Opera
keynum = e.which;
}

if (keynum == 13){
// 13 = return
document.form_name.submit();
}
}
function onEnter(e)
</script>
