Html – Update HTML Text Fields

html

How can I update the text fields with HTML? I have a page with some textfields, and I need to update these fields at a specific time. I used the value property to display the default values, but how can I change the values later?

Thank you

I am forcing a JavaScript answer, since there is no way it can be done with only HTML.

Snippet:

<input type="text" id="textboxid" />
<script type="text/javascript">
    var txtBox = document.getElementById("textboxid");
    txtBox.value = "new value";
</script>
