|
|
* The display is not yet object oriented. It's procedural code
|
|
* broken off into functions. It makes use of libphotofloat's
|
|
* PhotoFloat class for the network and management logic.
|
|
*
|
|
* All of this could potentially be object oriented, but presently
|
|
* it should be pretty readable and sufficient. The only thing to
|
|
* perhaps change in the future would be to consolidate calls to
|
|
* jQuery selectors. And perhaps it'd be nice to move variable
|
|
* declarations to the top, to stress that JavaScript scope is
|
|
* for an entire function and always hoisted.
|
|
*
|
|
* None of the globals here polutes the global scope, as everything
|
|
* is enclosed in an anonymous function.
