You should be a little clearer about what exactly you want to do. If you select View/View Source, then you will see that the circuit simulation Java applets are not stored on server that you linked to. They are elsewhere. Do you actually want the Java code used in the applets?
If you want only the animations, then you might try to screen capture the video. What do you want?
there is ability to copy the code of circuits and its elements. If you choose File->export the code list pops up and should be able to copy that, but that doesn't work.
