我有一個 JSON 月份串列，想從 React Native 的串列中選擇當前月份
這是我的清單
Month: [{ value: "1", label: "JAN", key: "JAN" },
{ value: "2", label: "FEB", key: "FEB" },
{ value: "3", label: "MAR", key: "MAR" },
{ value: "4", label: "APRIL", key: "APRIL" },
{ value: "5", label: "MAY", key: "MAY" },
{ value: "6", label: "JUN", key: "JUN" },
{ value: "7", label: "JUL", key: "JUL" },
{ value: "8", label: "AUG", key: "AUG" },
{ value: "9", label: "SEP", key: "SEP" },
{ value: "10", label: "OCT", key: "OCT" },
{ value: "11", label: "NOV", key: "NOV" },
{ value: "12", label: "DEC", key: "DEC" }
]
uj5u.com熱心網友回復：
您可以使用
const currentMonthIndex = new Date().getMonth() 1
月份通常從 0 開始，因此您必須添加 1 然后您可以過濾陣列
const selectedMonth = months.find(m => m.value === currentMonthIndex)

通過這樣做，它會為您提供陣列中的當前月份：
let Month = [
{ value: "1", label: "JAN", key: "JAN" },
{ value: "2", label: "FEB", key: "FEB" },
{ value: "3", label: "MAR", key: "MAR" },
{ value: "4", label: "APRIL", key: "APRIL" },
{ value: "5", label: "MAY", key: "MAY" },
{ value: "6", label: "JUN", key: "JUN" },
{ value: "7", label: "JUL", key: "JUL" },
{ value: "8", label: "AUG", key: "AUG" },
{ value: "9", label: "SEP", key: "SEP" },
{ value: "10", label: "OCT", key: "OCT" },
{ value: "11", label: "NOV", key: "NOV" },
{ value: "12", label: "DEC", key: "DEC" }
];
let currentMonth = Month[new Date().getMonth()];
console.log(currentMonth);轉載請註明出處，本文鏈接：https://www.uj5u.com/ruanti/357555.html
