Tutorial on saving DB array to local storage and vice versa

[Evgene Karachevtsev]

Hello Anil,

Variable data is available for absolutely all the services

[Anil Sagar]

Hi Evgene, variable "data" is not working for me in a query service. It returns "undefined" on using the following code on success of query service:

localStorage.setItem("Offers_LS", JSON.stringify(data.Offer));

Same code works absolutely fine in case of a read service.

Both services are displaying the same data on my page though.

Anil,

Entry data.Offer assumes that in response there is one object and it has the parameter Offer
You should output all variable data to the console and check this
preconsole.log(data);/pre

Hi Evgene, console shows as follows but alert says undefined on using alert(JSON.stringify(data.Offer));

Also, local storage also shows undefined for Offers_LS.

Mapping is exactly the same for read service which fills Offers_LS absolutely fine.

Hi Anil,

Try the following code please:prelocalStorage.setItem("Offers_LS", JSON.stringify(data[0].Offer));/pre

[Anil Sagar]

Yes this works. Thanks
