Hi,

Does Mootools have an equivalent to jQuery's isEmptyObject() function?
http://api.jquery.com/jQuery.isEmptyObject

You could use:

Object.every({}, function(){ return false }) // true
Object.every({a: 1}, function(){ return false }) // false

Or with simple JS:

var empty = true;
for (var k in object){ empty = false; break; }

Thanks for the reply. I think I will go for either of those JS solutions,
found on Stackoverflow:

function isEmpty(obj) {
    for(var prop in obj) {
        if(obj.hasOwnProperty(prop))
            return false;
    }

    return true;}

Or for ECMAScript 5 compatible browsers: Object.keys( obj ).length === 0

I think jQuery's function is useful, and would be welcome in Mootools.

A solution using hasOwnProp, while it may seem most complete, does
make its own assumption about emptiness. This may make it compatible
with jQuery but it's not the only definition: deliberately inherited
properties may suffice to make an object non-empty depending on your
ecosystem. YMMV....
