Download file from URL to the file system with PhoneGap

How can I download a file from URL to the file system with PhoneGap? I see there is a plugin for this (http://www.toforge.com/2011/02/phonegap-android-plugin-for-download-files-from-url-on-sd-开发者_运维技巧card/), but it's only for Android.

Are there any cross-platform solutions?

Looks like the FileWriter is supported on most platforms. I haven't tried it, but it might work for you.
