現在，我有引號的JSON文件，每次代碼運行時我都會獲得所有值。現在，我怎樣才能得到只有一（1）個值，並且每當我的頁面加載或刷新時，它都會改變或隨機化值。如何限制JSON值並隨機化頁面加載中的每個數據
儘管我在how to get random json data and append to div element上獲得了隨機化JSON文件的代碼，但它很難理解。
如何獲取一（1）個隨機JSON值？

查看複製我標記爲如何從數組中選擇一個隨機項。儘管如此，您應該注意，強制客戶端下載整個JSON文件只是爲了從中選擇一個項目，這是相當大的浪費時間。把你的服務器代碼寫成每個請求只返回一個單引號會更有意義。 –
@RoryMcCrossan即使它看起來很浪費時間。但對我來說它有一些目的。但還是要感謝評論，參考和建議。 – Ailyn
