MyValue : String;
MyValue := Window.SessionStorage.GetItem('my_value');
// How can I check if MyValue is null or not?
Right now I read a value and check if it is '1', and if it isn't then I assume my
settings are not initialised, but I'd rather have a better test.

Just use this:
if (MyValue=nil) then
ShowMessage('Value is null');
In EWB, strings, like arrays, can be nil if they haven't been assigned or
their length assigned via SetLength().
If you have any other questions, please let me know.
