How to use chrome.storage in a chrome extension using a variable's value as the key name?

Question

I\'m trying to use chrome\'s local storage / sync storage (chrome.storage) for an extension, to store data entries, for many different entries. I can\'t seem to figure out

Answer 1

the set method accepts object items, and an optional callback, the get accepts optional string or array or object keys and if you passed the first argument, you got to pass the second argument as well.

Example:

// To set 
chrome.storage.local.set({'testKey':'Test Value'});

// To get
chrome.storage.local.get('testKey', function(data){
  console.log(data); 
  // logs out "Object {testKey: "Test Value"}"
})
