带有Firefox插件SDK的SimpleStorage

Question

I'm working on an extension for Firefox v.42.0. In it, I have the Addon and on detecting a certain page, the addon injects some code into the page DOM. I am trying to use var simpleStorage = require("sdk/simple-storage"); to include simpleStorage. I save the variable as follows

simpleStorage.storage.token = $value;

and then trying to access the simpleStorage in the injected code as follows

if (private_self_options === undefined)
    var private_self_options = self.options;

var token = private_self_options.simpleStorage.storage.token;

However, this always returns an empty string. Could someone please point out my mistake?

Answer 1

You can get the contents of simpleStorage.storage.token into token with simply

var token = simpleStorage.storage.token

self.options is for use on the content script side, as shown here . Using it to pass information from simple-storage might be done thus:

tab.attach({
  contentScriptFile: "./content-script.js",
  contentScriptOptions: {
    token: simpleStorage.storage.token
  }
});

In that case, your assignment statement in ./content-script.js would be

var token = self.options.token;
