Javascript动态添加新的数组对象到现有数组中(使用键)?

I have an existing Javascript Array with Keys, like:

我有一个现有的带有键的Javascript数组，比如:

var myArray = new Array();
myArray.push({ "id":"A123", "pwd":"helloworld", "items":[] });

So the ..

所以. .

myArray["items"] <-------- will store multi-dimension Arrays inside again.

.. is currently a blank room.
Then now, how do I add new multiple Arrays into this myArray["items] room?

. .目前是空房间。现在，如何在myArray["items]空间中添加新的多个数组?

Lets say I have a loop to add items (total count is dynamic then):

假设我有一个添加项的循环(那么total count是动态的):

foreach(.......)
{
    var newItem = [{"itemcode": "i1001", "itemname": "apple"}];
    myArray.items.push( newItem ); // NOT WORKING
    myArray["items"] = newItem; // NOT WORKING ALSO
}

Simply debug like this:

简单的调试:

alert( JSON.stringify( myArray ) );

.. and it is returning the Array Structure but the "items" room is blank.

. .它返回数组结构，但是“items”空间是空的。

So how do I dynamically add new Objects into an existing Array room, with KEY, please?

那么如何动态地将新对象添加到现有的数组空间中呢?

The problem is myArray is an array, and the object which has items array is at index 0 so

问题是myArray是一个数组，而具有项数组的对象是索引0

myArray[0].items.push( newItem );

In your case there is no need to use an array, just use a object lik

在您的情况下，不需要使用数组，只需使用对象lik。

var obj = {
    "id": "A123",
    "pwd": "helloworld",
    "items": []
};
obj.items.push(obj);
