Closing an iPad webapp from HTML/Javascript?

I'm developing a webapp for iPad and i'm close to finish it (thank's to you guys by the way) but now that I'm pretty close I'm开发者_如何转开发 wondering and can't find documentation on how do I tell the browser to close the application onClick? Thanks a lot!

I haven't done iPad web apps but I've done them on some other platforms, and in all of them you close the app with:

window.close();

As a side note, iOS applications don't usually have close buttons, so perhaps you don't even need one?
