访问chrome.storage.sync

Question

I am working on a chrome extension that has 30 checkboxes on the options page. I am trying to save which checkboxes are checked using

var jsonfile={};
document.getElementById("teamdiv").addEventListener('change',function(e){
    jsonfile[e.target.id+""]=true;
    storeValue(jsonfile);
});

How can I retrieve all the values inside the jsonfile inside a different javascript file without having a seperate

chrome.storage.sync.get() 

statement? Thanks in advance.

Use Background Script in extension backgoundscript to communicate between pages

      {
        "name": "My extension",
         ...
        "background": {
           "scripts": ["background.js"]
         },
         ...
      }
