How do I use jQuery for flow control from an if statement?

Question

example:

if(login()) {

// jQuery to change CSS attribute from hidden to visible

}

I want to present the user with a input form if logged in, otherwise they don't see the form.

Thanks,

Check out jQuery hide()

if(login()) {

        $('#inputthing').show();

    } else {

        $('#inputthing').hide();
    }
