How To Save Data Using Only JavaScript?

Question

i need to save some changes and get it after reload the page !!

Answer 1

Look at web storage API: that's the modern replacement for cookies (which have also a JS kind-of API to handle them ^^):

https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API
https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie

Anyway, be aware that both are only supported in internet browser context (not working in androids app' html viewers -- webview)...
