I need to access a JSON array from outside of the scope of the sub-
function. I'm not sure how I can explain it more clearly...
Basically, I want to do this to save iterating over a specific anchor
class more than once. I'll try to provide an example.
Here is what I currently have to do:
$("a.item").each(function(index){
$(this).doStuff();
});
$.getJSON("example.js", function(json){
for(key in json){
$("a.item:contains(key)").addClass(json[key]);
}
});
As you can see, that means I am looping over the same set of anchors
multiple times, which seems wildly inefficient. I don't want to go
synchronously, because this is just a superficial change and shouldn't
delay a user's interaction with the page. Maybe the inefficient second
loop is the only way to do it.
At first glance, it seems moving the doStuff() function inside the
getJSON sub-function would be best, but there is no guarantee every
anchor will have an associated key, and they all need doStuff().
Any additional thoughts are appreciated.
