javascript - 如何在数组中呈现当天？

Question

我正在从我的应用程序中的 REST API 中提取一些数据，并尝试使用 moment 将当天解析为结果。

这是我的代码示例:

{restaurants.map((item, index) =>
<View key={item.id}>
<Text>
{`item.store_open_close.time.${currentDay.toLowerCase()}.opening_time`}</Text></View>
)}

但这是渲染，例如:item.store_open_close.time.thursday.opening_time

而不是我所期望的，例如:

上午 10:00

我觉得我快到了？任何帮助表示赞赏。谢谢!

PS - 我的餐厅数据如下所示

"store_open_close": {
        "enabled": true,
        "time": {
            "sunday": {
                "status": "close",
                "opening_time": "",
                "closing_time": ""
            },
            "monday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            },
            "tuesday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            },
            "wednesday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            },
            "thursday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            },
            "friday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            },
            "saturday": {
                "status": "open",
                "opening_time": "10:00 am",
                "closing_time": "7:00 pm"
            }
        },
        "open_notice": "We are open",
        "close_notice": "Sorry we are closed"
    },

Answer 1

您正在寻找这个:

<Text>{item.store_open_close.time[currentDay.toLowerCase()].opening_time}</Text>

之前您使用的是 string literal并且只在 js 中表达 ${currentDay.toLowerCase()}，但你想要整行。
