To count the number of objects in object literal using Jquery

Question

Code:

var animals = {
                    \"elephant\": {
                                    \"name\" : \"Bingo\",
                                    \"age\" :         


        

Answer 1

If you want something cross browser, that is also working on IE8, you can't do it in a really clean way (see compatibility of the keys property).

I suggest this :

var n = 0;
for (var _ in animals) n++;

(as it is an object literal, no need for hasOwnProperty)
