Yes, using the google chrome browser hit the f12 key, and click on the console button. Then use
you can log objects, arrays, strings ,variables. Much more useful than alerts.
Also in firefox the firebug plugin is quite useful. Has similar functionality, and adds the inspect element function that google chrome has built in.
EDIT:
Ok, based on your comment, you cannot just write to their file system. The browser will not let you. If you want something unobtrusive try something like a classy modal window or overlay, something that is optional for the user to interact with rather than the annoying alerts and confirms. You could even add something like this http://davidwalsh.name/dw-content/top-bar-opacity.php
