我的主要目標是遍歷這個并回傳一個新物件，其中包含至少有一位數字的專案，所以最后我會得到類似于這個例子的東西。新物件應該是一個新的 JSON 檔案：
{
"key": "ASDV1-01.jpg",
"data": {
"documentid": "CE44DBAC-59B2-4178-8392-0141FB2F58DF",
"scandate": "Feb 1 2018 12:05PM",
"F08": "1",
"F10": "101076",
}
}
當然，這應該應用于整個物件。試圖用正則運算式語法來做到這一點，但沒有用。先感謝您

數字是指 0 還是 a？（那么它將是一個字符）您可以遍歷整個 Json 并檢查每個鍵是否對應的值是 len() >= 1 如果是，則將其添加到新物件中。您還可以使用本示例中的過濾器（獲取所有奇數的示例）：
const odd = x => x % 2 === 1;
[1, 2, 3].filter(x => x % 2 === 1);

回圈遍歷整個影像陣列和test()鍵，如果它包含任何帶有/\d/正則運算式的數字
let data = [
{ "key": "no-digit.jpg" },
{ "key": "has2-digits7.jpg" },
{ "key": "again-no-digit.jpg" }
];
data = data.filter(item => /\d/.test(item.key));
console.log(data);轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/353991.html
