你编写jquery代码很好。问题是json文件不正确。 json对象的名称和值需要是双引号，如下所示

[ 
  {"name": "Afghanistan", "code": "AF"},
  {"name": "Ã…land Islands", "code": "AX"},
  {"name": "Albania", "code": "AL"},
  {"name": "Algeria", "code": "DZ"},
  {"name": "American Samoa", "code": "AS"},
  {"name": "AndorrA", "code": "AD"},
  {"name": "Angola", "code": "AO"},
  {"name": "Anguilla", "code": "AI"},
  {"name": "Antarctica", "code": "AQ"},
  {"name": "Antigua and Barbuda", "code": "AG"},
  {"name": "Argentina", "code": "AR"},
  {"name": "Armenia", "code": "AM"},
  {"name": "Aruba", "code": "AW"},
  {"name": "Australia", "code": "AU"},
  {"name": "Austria", "code": "AT"},
  {"name": "Azerbaijan", "code": "AZ"},
  {"name": "Bahamas", "code": "BS"},
  {"name": "Bahrain", "code": "BH"},
  {"name": "Bangladesh", "code": "BD"},
  {"name": "Barbados", "code": "BB"},
  {"name": "Belarus", "code": "BY"},
  {"name": "Belgium", "code": "BE"}
  ]
