Question

这是我想要设置的偏好：

{
        "name": "datestamp",
        "title": "Date stamp?",
        "type": "bool",
        "value": true
    }

下载插件代码，

preference.js

var preference = require("simple-prefs");

exports.set = function(preferenceTemp, value){
    console.log(value);
    preference.prefs[preferenceTemp] = value;
}

main.js

Preference = require("./Preference")

Preference.set('datestamp', true);

尝试执行时控制台出错：

console.error: addon: 
  Message: [Exception... "Component returned failure code: 0x8000ffff 
  (NS_ERROR_UNEXPECTED) [nsIPrefBranch.setComplexValue]"  nsresult: "0x8000ffff 
  (NS_ERROR_UNEXPECTED)"  location: "JS frame :: resource://gre/modules/XPIProvider.jsm

    /loader.js -> resource://gre/modules/commonjs/sdk/preferences/service.js :: set :: 
    line 92"  data: no]

问题是，我在代码中的其他地方传入一个未设置为布尔值的字符串这就是诀窍：

Preference.set('datestamp', 'true' === "true");

无法设置bool simple-prefs
