Putting table values into Local Storage

[Michael Smith]

I have a table called "company". One field is "compname" (Company Name).

The user can click on a checkbox to select the company which I can filter with
SELECT * FROM company where check01 = 1;

I am trying to find a way of saving this to local storage as "mcompname" with code as below.

localStorage.setValue('mcompname', company.compname)

This code does not work.

Any thoughts?
