ios 13 升級後 程序出現 openDatabase 異常

原創 29号同学 2020-06-23 22:59

在蘋果手機升級IOS13後，部分頁面突然打不開了，尤其是那些在前端做緩存處理的頁面。

常見的錯誤就是

window.openDatabase is undefined

主要原因：

蘋果在IOS13升級後，將safari的 WebSQL功能去掉了，除此之外還做了其他的調整，詳見Safari 13發行說明

解決方案：

1.用IndexedDB 代替 WebSQL

具體使用教程，可參見  瀏覽器數據庫 IndexedDB 入門教程

2.若移動端，用Cordova 套一層，然後用 SQLite 插件
