Json. WebHome < Main < Reprap. RepRap is humanity's first general-purpose self-replicating manufacturing machine.
RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own.
There are actually two flavours of each observer that check for value changes. The first is a periodic observer, which works like this: new Form.Observer($("myform"), 1, myCallBackFunction); new Form.Element.Observer($("myfield"), 1, myCallBackFunction); These observers check every second whether or not the data has changed and, if it has, will call myCallBackFunction. The second type of observer is event-based and will only perform the check when change or click events are produced for the elements. New Form.EventObserver($("myform"), myCallBackFunction); new Form.Element.EventObserver($("myfield", myCallbackFunction); If all the fields in the form you're observing support an event handler, this is a much more efficient way to observe the form.
