Hi mbc66 & dav123456,
Thank you for your shared interrest in extending Axure prototypes with custom javascript. As mbc66 describes the official method to do this is to use “AxShare” plug-ins. The limitation of this method is that it only works on prototypes hosted on AxShare. If the javascript must work when a prototype is previwed from Axure or hosted elsewhere then the “hack” is an option. Remeber that the hack is a hack, and may not work in new versions of Axure.
Thanks,
Sam
