How to catch last iteration inside $.each in jQuery?

Question

var arr = {'a':fn1,'b':fn2,'c':fn3}

$.each(arr,function(name,func){
(do something particular for the last iteration)
...
})

It'll be best if no additional variables are used.

EDIT: I mean LITERALLY last one,which is the last pair I type them.

Your example variable is called 'arr', but it's not an array at all (it's an object). This makes it a little confusing.

When iterating over an object, there's no such thing as a "last" property, because the order of properties is undefined by design.

When iterating over an array, you can simply compare the first parameter of the callback with the (array.length-1) to detect the last iteration.

In code (for arrays):

var arr = [ "a","b","c" ];

$.each(arr, function(i,val) { if (i == arr.length-1) ... });
