jquery push to make multidimensional array

Question

I've looked at other similar posts with no help, they all start with a multidimensional array already made, I want to magically make one by using .push.

My array:

ItemsArray.push({ 
                   RoomName : RoomName, 
                   Item : {//this is where I want the multi-array } 
               });

I tried using: ItemsArray.Item.push{ stuff:morestuff } but it stopped saying 'ItemsArray.Item' is not defined... which is clearly ridiculous ?

Also tried: ItemsArray[1].push{} with same error...

Surely this must be a stupid simple problem.

Thanks!

Answer 1

You are creating Item as an object. You want it to be an array to be able to push into it.

var ItemArray = [];
ItemArray.push({
    RoomName : 'RoomName', 
    Item : []
});

ItemArray[0].Item.push("New Item");

console.log(ItemArray);

Here is a good blog post that has in-depth detail about the difference between objects and arrays.
