Counting an Object's Children

Recommended Posts

I'm using objects as associative arrays in Javascript.

 

var Cake = new Object();
Cake['ice cream'] = 'yummy';
Cake['chocolate'] = 'mmm';
Cake['none'] = 'aww...';

 

Do objects have a method or property that would tell me how many elements the pseudo-associative array Cake has?

 

Please don't tell me the only way is to loop through each element and count them.

 

Thanks.  :)

I don't think so. If you declare it as an Object, the category that all JavaScript data falls under, then I doubt it has an abstract length function that calculates that. Best you can do is change the Cake to an array and then loop through that or create your own function/method for it. There is no length method for an associative array in JavaScript either.
