I'm reading the Jquery Novice to Ninja book and on page 268 where there is this unexplained snippet of code containing a selector $(which);
I do not know what this means. Reading this book is FRUSTRATING as I have to keep a laundry list of things I got to research when something is not explained, but the string $(which); is NOT searchable as it seems to be mis-interpreted so I have to ask here. What does this piece of code mean???!?!??
Ok, on fourth read, I note that the text says its's storing our what the user has started to drag, but I would like to see some further explanation about what is the difference between this and $(which) and how do I know which of these I'm supposed to use?
The over all effect of having foreign syntax used without explanation is like taking a foreign language course where words are used without defining them in sentences and you have to guess what the word means and of course like the Indiana Jones movie where they have to chose the right cup out of many, the chances of a wrong guess and needed unlearning are great!
