document.getElementById('<%= divpassword.ClientID %>').style.display = 'block';

Answer 1

You can use runat="server" and also hide the div from javascript using clientidmode="static" .

<div id="divpassword" runat="server" clientidmode="static" style="display: none;" >
----
----
</div>

document.getElementById('divpassword').style.display = 'block';

Answer 2

It can be very easily done if you use jQuery.

$( "#divpassword" ).hide();

And if you need to do it in pure java script, the following link might help - Show/hide 'div' using JavaScript
