更新......

与ADDRESS属性混淆的换行符。只需在使用字符串之前删除所有换行符，就可以了：

 var headers = lines[0].split(",");
 for (var i = 1; i < headers.length; i++) {
    var header = headers[i];
    header = header.replace(/(\r\n|\n|\r)/gm,"");
    headers[i] = header;
  }

~~我真的无法找出为什么ADDRESS属性被包围在引号中并且无法访问，但是数组修复了问题...~~

~~我会调查更多以解决问题，但~~只是为了您的目的使用演示中的代码http://jsbin.com/hatasaf/2/edit?js,output
