将javascript数组插入另一个数组

Question

考虑以下两个数组.如何将数组"行"附加到数组"array1".我试过.push但是它附加在数组之外.我也试过.unshift,它没有给我想要的结果.

array1 = [
  {
    "Activity #": "1111111",
    "Customer": "Last, First",
    "Tenure": "0 Year 2 Months",
    "Account #": "0000000"
  }];

lines = [
  {
    "Line #": "1",
    "Action Required": "New",
    "Status": "Closed",
    "Product Line": "test line1",
    "Product": "product1"
  },
  {
    "Line #": "2",
    "Action Required": "New",
    "Status": "Closed",
    "Product Line": "test line2",
    "Product": "product2"
  }];

我想要这样的东西.

my_array = [
{
    "Activity #": "1111111",
    "Customer": "Last, First",
    "Tenure": "0 Year 2 Months",
    "Account #": "0000000",
    "lines": [{
            "Line #": "1",
            "fields": "keys"
        },
        {
            "Line #": "2",
            "fields": "keys"
        }]
}] 

通过上面提到的使用方法我得到了类似的东西

my_array = [
{
    "Activity #": "1111111",
    "Customer": "Last, First",
    "Tenure": "0 Year 2 Months",
    "Account #": "0000000"
}, [
    {
        "Line #": "1",
        "fields": "keys"
    }, {
        "Line #": "2",
        "fields": "keys"
    }]
];

希望有人可以提供帮助,我的问题很明确.

看起来你想要lines在数组中添加属性到对象,所以你必须这样做:

array1[0].lines = lines;

如果你有更多的元素array1,你还没有解释究竟应该发生什么,所以我不能说什么.
