Clear password text box on submit

I have an intranet page with a link to a coldfusion/sql server based project log. When one clicks on the link the first cfm page is a login page. When the user hits the submit button the first page of the project log opens in a new window (and hence, subsequent pages of the project log).

The problem is that the password remains behind in the parent window. Is there any code I can include that says clear the text field when the user hits the submit button?
