Changing value of text fields not inside form

S

Why doesn't this work? :-

<BODY onkeydown="display(event)">
<input type="text" name="text1">
<script language="Javascript">
function display(event) {
document.text1.value = event.keyCode+' : '+String.fromCharCode(event.keyCode);
}
</script>
</BODY>

Error: document.text1 has no properties

I have to put it in a Form to get it to work :-

<BODY onkeydown="display(event)">
<form name="form1">
<input type="text" name="text1">
</form>
<script language="Javascript">
function display(event) {
document.form1.text1.value = event.keyCode+' : '+String.fromCharCode(event.keyCode);
}
</script>
</BODY>

It is OK to put form controls into an HTML page without making
them part of a form. However, if you do, you don't have access
to certain features that are available when they are part of a
form. For example, they can never be successful and so can't be
submitted as if they were in a form.
