Как экспортировать массив JavaScript в базу данных MySQL

0 голосов
/ 07 февраля 2019

У меня есть массив в JavaScript для отображения в качестве селектора на моей веб-странице.

Теперь я хочу экспортировать этот массив в базу данных MySQL и сделать селектор на моей веб-странице редактируемым из пользовательского интерфейса.

У меня проблемы с сохранением массива в базе данных.

Большая часть поста, который я видел, использует php, мне нужно только сделать это с помощью javascript и sql. 

const SEIKO = "seiko";
const WSL = "wsl";


const DATAFEED = SEIKO;


const SEIKO_EVENTS = [
