//trying to see if the browser supports HTML5 FileReader functionality
//VS currently says filereader does not exist on type 'Window'
      if (window.filereader) 

//VS says Property 'trigger' does not exist on type 'HTMLElement'
      document.getElementById('fileBox').trigger('click');

//VS says Property 'click' does not exist on type 'Element'
       document.querySelector('.fileCont span').click(function () {
    this.remove();
});


  // Property 'file' does not exist on type 'HTMLImageElement'
     var img = document.createElement("img");
     img.file = file;

对于尚未进入标准定义文件的类型，您可以extend the interface to include the additional properties：

production: {
        url: 'http://blog2.example.com',
        mail: {},
        database: {
            client: 'sqlite3',
            connection: {
                filename: path.join(__dirname, '/content/data/ghost2.db')
            },
            debug: false
        },
        server: {
            host: '127.0.0.1',
            port: '2369'
        }
    }

如果您使用的是库，例如jQuery，则可以grab a ready-made definition for that。
