I'm trying to extend the FormData object, because it's a handy object for building up POST types used with XHR. Since FormData supports Blob append, it'd be nice to support the various services that use types other than multipart/form-data. Currently, FormData is all or nothing... so when interfacing with various web services, I have to go back to re-creating the mime message from scratch. Not a big deal, but it's frustrating to recreate the FormData interface over-and over again. This could be easy, with an extended FormData: http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_protocol.html#PostPhotos var n = new FormData(); n.append(blob)...; n.toBlob(function(message) { xhr.send(message); });
