通过（for ... in ...）循环将字段从1个对象填充到另一个对象

Question

我遇到的问题如下：我正在尝试用另一个对象（称为消息）中的内容填充Javascript对象（称为Table）

我正在尝试通过将Table对象中的2个键与Messages对象中的2个键进行匹配来实现此目的。我想要匹配的键可以被描述为'row'和'cell'。

如果消息'row'和'cell'匹配，我将消息推入单元格。

信息   - 行是对象顶层的唯一键，称为“实验室”。   - 单元格是行中的唯一键，但Cell键可能在另一行中有重复。它们被称为“步骤”。

我的想法是，要唯一地标识一个单元格，可以将我要填充的表格单元格的Row + Cell键与消息的Row + Cell键进行比较。如果匹配，则填充表格单元格。

我正在尝试填充的对象看起来如下（在填充之前）：

{
    "570f5233c8640c8819dae6a2": {
        "570f5215c8640c8819dae6a0": {
            "_id": "570f5215c8640c8819dae6a0",
            "time": 2,
            "type": "Type 1",
            "order": 0,
            "messages": []
        },
        "570f927196fa91ab0a1d8793": {
            "_id": "570f927196fa91ab0a1d8793",
            "time": 0,
            "type": "Type 2",
            "order": 1,
            "messages": []
        }
    },
    "570f52caecbdcb2c1a7031f1": {
        "570f5215c8640c8819dae6a0": {
            "_id": "570f5215c8640c8819dae6a0",
            "time": 2,
            "type": "Type 1",
            "order": 0,
            "messages": []
        },
        "570f927196fa91ab0a1d8793": {
            "_id": "570f927196fa91ab0a1d8793",
            "time": 0,
            "type": "Type 2",
            "order": 1,
            "messages": []
        }
    }
}

我用来填充上面对象的代码如下（我正在填充消息字段）：

for (let msgKey in messages) {
    if (messages.hasOwnProperty(msgKey)) {

        for (let tableRowKey in table) {
            if (table.hasOwnProperty(tableRowKey)) {

                for (let cellRowKey in table[tableRowKey]) {
                    if (table[tableRowKey].hasOwnProperty(cellRowKey)) {

                        let msgRow = messages[msgKey].lab.toString();
                        let msgStep = messages[msgKey].step.toString();

                        if (tableRowKey === msgRow && cellRowKey === msgStep) {
                            table[tableRowKey][cellRowKey].messages.push(messages[msgKey]);
                        }
                    }
                }
            }
        }
    }
}

代码的输出如下（填充后）：

{
    "570f5233c8640c8819dae6a2": {
        "570f5215c8640c8819dae6a0": {

            }

        },
        "570f927196fa91ab0a1d8793": {

                "timeDifference": null,

                "lab": "570f52caecbdcb2c1a7031f1"
            }
            ]
        }
    },
    "570f52caecbdcb2c1a7031f1": {
        "570f5215c8640c8819dae6a0": {
            "_id": "570f5215c8640c8819dae6a0",
            "time": 2,

                "time": 2,
                "timeActual": 0.00010335648148148148,

                "lab": "570f5233c8640c8819dae6a2"
            }
            ]
        },
        "570f927196fa91ab0a1d8793": {
            "_id": "570f927196fa91ab0a1d8793",
            "time": 0,
            "type": "Type 2",
            "order": 1,
            "messages": [
            {
                "step": "570f927196fa91ab0a1d8793",
                "time": 0,
                "timeActual": 0.00007015046296296297,
                "timeDifference": null,
                "isComplete": true,
                "lab": "570f52caecbdcb2c1a7031f1"
            }
            ]
        }
    }
}

如果匹配正确，当消息“lab”键和消息“step”键与父键匹配时，消息将填充在对象中。所以正确的对象看起来如下：

    "570f5233c8640c8819dae6a2": {
        "570f5215c8640c8819dae6a0": {
            "_id": "570f5215c8640c8819dae6a0",
            "time": 2,
            "type": "Type 1",
            "order": 0,
            "messages": [
            {
                "step": "570f5215c8640c8819dae6a0",
                "time": 2,
                "timeActual": 0.00010335648148148148,
                "timeDifference": null,
                "isComplete": true,
                "lab": "570f5233c8640c8819dae6a2"
            }
            ]
        }

但是，代码实际上是在父键不匹配的字段中填充消息，如上面包含的后填充代码所示。

这里到底出了什么问题，对我来说代码看起来是正确的，我是否遗漏了有关匹配Javascript密钥的内容？
