Where is the second argument in multiplier()? I'll try to explain in
example:
function multiplier(obj, times) {
times = isNaN(times) ? 2 : times;
if (typeof obj.value != 'undefined') {
return obj.value * times;
} else {
alert(obj + ': does not have a value property!');
}
}
obj_a.multiply = multiplier.methodize();
multiplier(obj_a, 2); // same as obj_a.multiply(2);
obj_a.multiply(2); // same as multiplier(obj_a, 2);
