trigger login window

I do a JQuery trigger on a login button to auto login. It works fine in IE but in Firefox i get this login window. My question is:

Can I trigger the click on OK with jQuery?

 j开发者_JS百科Query(document).ready(function(){
              jQuery('.centerButton').trigger('click');
    });

No. It is browser chrome and not part of the DOM so it isn't accessible.

You can not interact with windowed elements [prompts, alerts, etc] with JavaScript.
