How can I get the value of the array on index?.

Are you sure there is correct json in localStorage variable?
How do you save it?
Show it in alert to see what is stored in localStorage.

It's not json in your localStorage. In maping from Marker to id add the following JS prereturn JSON.stringify(value);/pre
