Yeah, roughly. But see below.

>2) What is evt.stopPropagation() ?

When an event happens (e.g., click on a table cell), you can have a
handler on the cell which handles the event. But the event propagates
up and down so that the row that the cell is in gets gets the event
too, and so on up to the body. If you have click handlers there, they
will also get called. If you want to stop that happening, you need to
call evt.stopPropagation() in the last handler that you want to have
deal with the event, and it won't propagate any further.

The above is incomplete and slightly erroneous, but good enough for
this explanation. My advice is indeed to delve into your JS books, and
read up on the various event models, and event propagation/bubbling, to
see more detail and to understand better.

My books are JavaScript: The definitive guide by David Flanagan, and
the JavaScript Bible 7th Edition (Goodman et al). All editions of both
books are out of date before they are even purchased (I'm on my second
version of Flanagan and third of Goodman) so you have to be a bit
careful, but by and large they'll do and they go into some detail about
a large number of things. Expect to replace books with newer editions
on a regular basis.

People here will argue the toss all day about this or that author being
a fool and incompetent, I'd say go on Amazon and Read Inside various
books to see which authors have writing styles that suit you and screw
the wise guys.
