Need help with Read/Write from LocalStorage
Posted: Thu Jan 25, 2018 12:36 pm
Hello, I use the following procedures to save/load cookies.
Unfortunately, these are lost after closing the browser. That's why I want to use the local storage for storing.
I would like to integrate these localstorage accesses into the code like the cookies.
The help describes how to load and save using a callback. How would it have to be reprogrammed so that it could be done as described above?
Code: Select all
Procedure SetCookie(Name.s, Value.s)
Protected Buffer.s = Name + "=" + Value
! document.cookie = v_buffer;
EndProcedure
Procedure.s GetCookie(Name.s)
! var value = "; " + document.cookie;
! var parts = value.split("; " + v_name + "=");
! if (parts.length == 2) return parts.pop().split(";").shift();
EndProcedure
I would like to integrate these localstorage accesses into the code like the cookies.
Code: Select all
SetLocalStorage (Name.s, Value.s)
value.s = GetLocalStorage (Name.s)
Code: Select all
