js实现汉字中文排序的方法 例如：省市列表的排序

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"]

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‘}}]*/
