js实现汉字中文排序的方法 例如：省市列表的排序

localeCompare() 

　　1.数组内的元素是中文字符串的简单排序

var arr = ['南京', '北京', '上海', '杭州', '深圳'];
  function sortChinese (arr) { // 参数： 排序的数组
    arr.sort(function (item1, item2) {
      return item1.localeCompare(item2, 'zh-CN');
    })
  }
  sortChinese(arr)
  console.log(arr); //  ["北京", "杭州", "南京", "上海", "深圳"]

　　2.数组内的元素是对象，以对象某一个属性进行排序

var arr = [
    {name: '南京', code: '09', info: {province: '江苏'}},
    {name: '北京', code: '01', info: {province: '北京'}},
    {name: '上海', code: '02', info: {province: '上海'}},
    {name: '深圳', code: '05', info: {province: '广东'}}
  ];
  function sortChinese (arr, dataLeven) { // 参数：arr 排序的数组; dataLeven 数组内的需要比较的元素属性
    /* 获取数组元素内需要比较的值 */
    function getValue (option) { // 参数： option 数组元素
      if (!dataLeven) return option
      var data = option
      dataLeven.split('.').filter(function (item) {
        data = data[item]
      })
      return data + ''
    }
    arr.sort(function (item1, item2) {
      return getValue(item1).localeCompare(getValue(item2), 'zh-CN');
    })
  }
  sortChinese(arr, 'name') // 例如：比较的是name，传入的就是 'name'
  console.log(arr);
  /*[{name: '北京', code: '01', info: {province: '北京'}},
  {name: '南京', code: '09', info: {province: '江苏'}},
  {name: '上海', code: '02', info: {province: '上海'}},
  {name: '深圳', code: '05', info: {province: '广东'}}]*/
  sortChinese(arr, 'info.province') // 例如：比较的是数组元素属性info内的province属性，传入的就是 'info.province'
  console.log(arr);
 /* [{name: '北京', code: '01', info: {province: '北京'}},
  {name: '深圳', code: '05', info: {province: '广东'}},
  {name: '南京', code: '09', info: {province: '江苏'}},
  {name: '上海', code: '02', info: {province: '上海'}}]*/

　　3.对国内的所有省份进行排序，并且首字母相同的第一个添加首字母

 var provinceList = [
    {"code": "82", "value": "澳门"},
    {"code": "34", "value": "安徽"},
    {"code": "11", "value": "北京"},
    {"code": "50", "value": "重庆"},
    {"code": "35", "value": "福建"},
    {"code": "62", "value": "甘肃"},
    {"code": "44", "value": "广东"},
    {"code": "45", "value": "广西"},
    {"code": "52", "value": "贵州"},
    {"code": "46", "value": "海南"},
    {"code": "13", "value": "河北"},
    {"code": "41", "value": "河南"},
    {"code": "23", "value": "黑龙江"},
    {"code": "42", "value": "湖北"},
    {"code": "43", "value": "湖南"},
    {"code": "22", "value": "吉林"},
    {"code": "32", "value": "江苏"},
    {"code": "36", "value": "江西"},
    {"code": "21", "value": "辽宁"},
    {"code": "15", "value": "内蒙古"},
    {"code": "64", "value": "宁夏"},
    {"code": "63", "value": "青海"},
    {"code": "37", "value": "山东"},
    {"code": "14", "value": "山西"},
    {"code": "61", "value": "陕西"},
    {"code": "31", "value": "上海"},
    {"code": "51", "value": "四川"},
    {"code": "71", "value": "台湾"},
    {"code": "12", "value": "天津"},
    {"code": "54", "value": "西藏"},
    {"code": "81", "value": "香港"},
    {"code": "65", "value": "新疆"},
    {"code": "53", "value": "云南"},
    {"code": "33", "value": "浙江"}
  ]
