Global object

[avianmanagement]

Thanks Barry,

The local storage looks a very good way to do it using

lnDays = Lianja.localstorage.getItem(‘oApp’).ndays

I can easily do a search and replace in my code using that for my existing calls

That way I just need to have one code to make the objects in all platforms.

Many thanks

Hi David

To avoid polluting localstorage on web i recommend you have an "aims" object that contains everything else.

[avianmanagement]

Thanks Barry,

So to create that I first create the aims object then add opref to it then use setitem('aims.opref',aims.opref)

In the above if I later create aims.oegg is that treated as a separate object, added to the existing aims object in local storage or overwrites it?

Or should I create an object aims then setitem('aims',aims) then reference that to add oPref to it?


The oPref object is used for setting for code. Things like oEgg are passed as parameters to code, so they I assuem can just be created as object at the time and passed around rather than using local storage for them?

Hi David,

Or should I create an object aims then setitem('aims',aims) then reference that to add oPref to it? Yes.

aims = object()
Lianja.localstorage.setItem("aims", aims)

as "aims" is an object it can be assigned anywhere and its contents are shared. Am object reference in fact.

aims.oApp = object()
aims.oApp.oPrefs = object()

etc.

Hi Barry

if !used(dpref)
use dpref in 0
endif
clear

select dpref
Scatter name oPref

? oPref.NUPDATEDAYS && works and prints 14 as expected
Lianja.localstorage.setItem('oPref',oPref)
* ? Lianja.localstorage.getItem(‘oPref’)

? Lianja.localstorage.getItem('oPref').NUPDATEDAYS

Lianja.localstorage.setItem('oPref.NUPDATEDAYS',2)

? Lianja.localstorage.getItem('oPref').NUPDATEDAYS

I would have expected this to print 14 then 2, it prints 14 once

Can you please tell what I'm doing wrong.

Lianja.localstorage.setItem('oPref.NUPDATEDAYS',2) is meaningless

The item is a member name not an arbitrary expression.

Hi Barry,

This does not print anything to the console

*Lianja.localstorage.removeitem('oPref')

select * from dpref into cursor temp1
select temp1
Scatter name oPref

* ? oPref.NUPDATEDAYS && works and prints 14 as expected

Lianja.localstorage.setItem('oPref',oPref)
? Lianja.localstorage.getItem('oPref').NUPDATEDAYS

Nothing printed

[avianmanagement]

Lianja.localstorage.setItem('oPref.NUPDATEDAYS',2) is meaningless

The item is a member name not an arbitrary expression.

So how does one alter the value of oPref.NUPDATEDAYS in the local storage?


Lianja.localstorage.getItem('oPref').NUPDATEDAYS = 2 ?

[barrymavin]

Yes

[avianmanagement]

Thanks Barry,

I'll get the hang of this one day

? Lianja.localstorage.getItem('oPref').NUPDATEDAYS

I get no output to the console on this

where as the OPref object before it's added using the setitem does have a value for NUPDATEDAYS
