Question

Hay, i have the following list

var feedObjects = {
    0:[
        "url",
        "image"
    ],
    1:[
        "url",
        "image"
    ]
}

However when i try doing feedObjects.length it always returns null, any ideas?

Answer 1

You have an Object ({} are the literal Object notation), not an Array, so there is no length property.

You will need to iterate over it with for ( in ), except this guarantees no ordering of the properties, unlike an Array (though in practice they generally come in the order defined).

Better still, swap { } with [ ] and use a real Array (well as close as JavaScript’s arrays are to real ones).
