javascript - 在 javascript 中创建具有自定义结构的对象

Question

我需要创建一个具有这种精确结构的数组对象：

{"item1": {
    0 :  {
        color:"description1",
        width:"description2",
        height:"description3"
    }
    1 :  {
        color:"description1",
        width:"description2",
        height:"description3"
    }
    //and so on
},
"item2": {
    0 :  {
        color:"description1",
        width:"description2",
        height:"description3"
    }
    //and so on
}
//and so on
}

静态工作正常。现在，我想让它动态化。所以，主要问题是......如何在构建对象的同时循环数据？这是我工作的传入对象的示例：

[
{
    "uid": 1,
    "legendname": "item1",
    "rows": [
        {
            "uid": 0,
            "color": "482400",
            "width": "482400",
            "height": "25"
        },
        {
            "uid": 1,
            "color": "587898",
            "width": "789658",
            "height": "30"
        }
    ]
}
{
    "uid": 2,
    "legendname": "item2",
    "rows": [
        {
            "uid": 0,
            "color": "482400",
            "width": "482400",
            "height": "25"
        }
    ]
}
]

如何在构建对象的同时循环数据？

不清楚。但是如果你想根据传入的结构创建一个新结构，你可以使用这个：

// ar = your incoming object
// b_obj = your result

var b_obj = {}
for (var i = 0; i < ar.length; i++)
{
    item = ar[i];
    b_item = {};
    for (var i_row = 0; i_row < item.rows.length; i_row++)
    {
        var row = {};
        row.color = item.rows[i_row].color;
        row.width = item.rows[i_row].width;
        row.height = item.rows[i_row].height;
        b_item[i_row] = row;
    }
    b_obj[item.legendname] = b_item;
}
