        src = document.getElementById("fname");
        dest = document.getElementById("sitename");
        dest.value = src.value;
    }
</script>

Answer 1

This is pretty doable with jQuery:

$('#fname').keyup(function(event) {

    event.stopPropagation();

    $('#sitename').val($('#fname').val());
});

You will have to remove your copyText() function for this to work.

Hope this helps.

Answer 2

I assume you want something like this

if a user enters a name for eg 'StackOverflow'

in the second input box you want to have 'StackOverflow.co.in' where '.co.in' is your permanent text to the text box

However for this you can use simple javascript

<input id = "firstName" onkeyup="copyText()" />

<Input id = "siteName" value =".co.in" />

<script type="text/javascript">
function copyText(){
    var firstName = document.getElementById('firstName').value ;
    document.getElementById('siteName').value = firstName + '.co.in' ;
}
</script>
