Nick, just use FileWriter.write to save your JSON data to disk. JSON is a text based file anyway so there is no need to set the mime type. When you are ready to load the file again use FileReader.readAsText. In your "onloadend" handler of the FileReader the method will be called with an event and event.target.result will be your JSON data. Then you'll do a

Nick，只需使用FileWriter.write将您的JSON数据保存到磁盘。无论如何，JSON是基于文本的文件，因此不需要设置mime类型。准备好再次加载文件时，请使用FileReader.readAsText。在FileReader的“onloadend”处理程序中，将使用事件调用该方法，event.target.result将是您的JSON数据。然后你会做一个

var myJson = JSON.parse(event.target.result);

to turn the text into a JSON object.

将文本转换为JSON对象。

(for template or default settings) I just store them in seperate constant files so i don't have to use any special file utility addons or commands, super easy:

（对于模板或默认设置）我只是将它们存储在单独的常量文件中，因此我不必使用任何特殊的文件实用程序插件或命令，超级简单：

(function(){
angular.module('app').constant('settings_json', 
{  
    "name":"settings",
    "data":[  
       {  
          "set":"globals",
          "share_diagnostics":true,
          "user_prefs_save_cloud": true         
       },
       {
          "set":"user",
          "fname":'',
          "lname": '',
          "telephone": '',
          "email": ''       
       }
    ]
}
)})();

Then in your app: (after injecting 'settings_json')

然后在你的应用程序中:(在注入'settings_json'之后）

var settings = angular.fromJson(settings_json);
