如何在firebase中添加元素数组？

问题描述：

我想知道如何简单地将数据从数组存储到Firebase。让我们考虑一下，我有一个元素数组。

I want know how to simply store the data from the array to firebase. Let us consider that I having an array of element.

function Something() {
    var elements=new Array()
    elements[0]=10;
    elements[1]=20;
    elements[2]=30;

    database = firebase.database();
    var ref = database.ref('ExTable');
    ref.set(elements);
}

ref.set（elements）; 函数会将数据保存到我的Firebase数据库中？

Will the ref.set(elements); function will save the data to my firebase DB?

现在，此数组包含三个值，我如何将它们作为任何父节点下面的节点存储到Firebase。像

Now this array contains three values, and how can I store them to firebase as nodes below any parent node. Like

+---Parent
      |
      |
      +---0
      |   |
      |   |
      |   +---10
      |
      |
      +---1
      |   |
      |   |
      |   +---20
      |
      |
      +---2
          |
          |
          +---10

我想像上面的示例一样存储它们。因为我的数组有时包含各种数量的元素。

I want to store them as like in the above example. Because my array sometimes contains various number of elements.

答

只需将其传递给对象数组，如下所示。

Just pass it with array of objects like shown below.

var array = [];

array.push({"name":"Barry"});
array.push({"name":"Allen"});

ref.push(array);
