FWIW, I'd say it's a clever use of bind(). The question of whether
it's what bind() is *for* is kind of moot. (I'd say, on balance, yes
it is -- bind() is for binding functions to objects [or maybe vice-
versa]. This isn't the way you normally see it used, but that's a
different matter...) So yeah, if you don't need the context ("this")
for some other purpose, no reason you can't do it like that.
Once you're at the point where you have your JSON data turned back
into an object (I'll call it 'json'), hooking up an event handler
would look like this:
$('someElement').observe('click', clickHandler.bind(json));
Then when someone clicks that element and your clickHandler() function
is called, you have access to 'json' within your function as "this":
function clickHandler(evt)
{
// Get the blarg from json:
var blarg = this.blarg;
}
I don't think I've seen anyone do quite that thing before, but it
seems like a perfectly valid use of bind().
HTH,
