Can you use Javascript to put date/time into form input onload?

Question

I am trying to put the date and time into a form field onload. Am I doing something wrong here, I can't get it to work. Here is my code:

<HEAD>
<script type="text/javascript">
            function updateData()
            {
                var cl_dt=new Date();
                document.getElementByName("lastpost_cl").value=cl_dt;
            }
</script>
</HEAD>

<BODY onLoad="updateData();">

<form id="FormName" action="updated.php" method="post" name="FormName">
<input id="lastpost_cl" name="lastpost_cl" type="text" size="25" maxlength="255">

Why not just use jQuery? In the '$(document).ready' jQuery function just set the default value like '$("#lastpost_cl").val = new Date();'. Will handle it easier. — subv3rsion

Just a footnote: Don't use uppercase tag names like <BODY> and <HEAD>, nor camel case attributes like onLoad - stick with lower case all the way. Also, if this is the full scope of what you're trying to do don't bother with jQuery; it would be like killing an ant hill with the Stark Jericho missile. — Richard JP Le Guen

Use getElementById. getElementsByName (There is an 's' after Element!) returns a collection of element(s).

getElementByName does not exist, at least not cross browser. Use getElementById instead. You already have an ID that is the same, so it will work with just that change.
