Interface

Namespace should always be GB2260.

Data Structure

There is a standard structure named Division. Those following properties should be included in it.

• code: (str) The six-digit number of the specific administrative division.
• name: (str) The Chinese name of the specific administrative division.
• revision: (str) The revision year (month).

For example, a county of Beijing in JavaScript is defined like this:

{
  "code": "110105",
  "name": "朝阳区",
  "revision": "2014"
}

The administrative level representation depends on recursion records. The division codes XX0000 (X is non-zero digit) mean provinces. And there are XXXX00 for prefectures and XXXXXX for counties.

{
  "code": "110100",
  "name": "市辖区",
  "revision": "2014"
}

{
  "code": "110000",
  "name": "北京市",
  "revision": "2014"
}

.province

Return province level division of current division.

.prefecture

Return prefecture level division of current division. If current division is a province, return none/null/nil.

.description

A description of current division. e.g.

北京市 市辖区 崇文区

Methods

The interface MUST have a constructor method to create a new instance:

gb2260 = new GB2260(str revision)

If revision is not specified, use the latest data.

.get(str code)

Return the division of the given code.

gb2260.get("110105")

// =>
{
  "code": "110105",
  "name": "朝阳区",
  "revision": "2014"
}

.provinces() 省

Return a list of provinces in Division data structure.

.prefectures(str province_code) 地级市

Return a list of prefecture level cities in Division data structure.

A province_code is a 6-length province code. It can also be:

• 2-length code
• 4-length code that endswith 00

.counties(str prefecture_code) 县

Return a list of counties in Division data structure.

A prefecture_code is a 6-length code that endswith 00. It can also be a 4-length code.

#revisions()

List all revisions supported by GB2260 in descendant.

Additional Information

The code value is always a string. In weak typed languages, the parameter for code, province_code and prefecture_code can also be int.
