Current Date In Input Field?

I need to write the current date (dd/mm/yyyy) inside an input element like this Code:<input name="name" type="text" id="id" value="current date here"> I know this code can give me the current date, but i don't know how to write it in the input element

Code:
<script type="text/javascript">
<!--
var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFullYear()
document.write(month + "/" + day + "/" + year)
//-->
</script>
