How do you get browsers to recognize a password change?

As I'm sure you are aware, a feature on most browsers is that they save passwords. Now, I have a site where a user can change their password on one of the pages. Is there a way to get the b开发者_运维问答rowser to recognize the change?

In other words, the I want the browsers to bring up their "save new password" dialog when a user enters their new password in a certain field. Is there a way to do this?

Obviously, a pure html solution is preferred, but I'd be happy to hear of ways to do this in Javascript.

FYI, the site I am working does not require very strong security.

It should be as simple as <INPUT TYPE="password" AUTOCOMPLETE="on" ...
