JS实现中文汉字按拼音排序的方法

本文实例讲述了JS实现中文汉字按拼音排序的方法。分享给大家供大家参考，具体如下：

代码1，拼音排序：

var array = ['武汉', '北京', '上海', '天津'];
var resultArray = array.sort(
 function compareFunction(param1, param2) {
  return param1.localeCompare(param2,"zh");
 }
);
console.log(resultArray);

火狐浏览器 resultArray 结果为：

[ '北京' , '上海' , '天津' ,'武汉' ] ;

代码2，拼音排序并按字母分类：

function pySegSort(arr,empty) {
 if(!String.prototype.localeCompare)
  return null;
 var letters = "*abcdefghjklmnopqrstwxyz".split('');
 var zh = "阿八嚓哒??发旮哈讥咔垃???噢?r七??P它?夕丫??".split('');
 var segs = [];
 var curr;
 $.each(letters, function(i){
  curr = {letter: this, data:[]};
  $.each(arr, function() {
   if((!zh[i-1] || zh[i-1].localeCompare(this,"zh") <= 0) && this.localeCompare(zh[i],"zh") == -1) {
    curr.data.push(this);
   }
  });
  if(empty || curr.data.length) {
   segs.push(curr);
   curr.data.sort(function(a,b){
    return a.localeCompare(b,"zh");
   });
  }
 });
 return segs;
}
JSON.stringify(pySegSort(["我","不","懂","爱","啊","按","已","呀","选","县"]))

结果：

"[
{"letter":"a","data":["啊","爱","按"]},

{"letter":"b","data":["不"]},

{"letter":"d","data":["懂"]},

{"letter":"w","data":["我"]},

{"letter":"x","data":["县","选"]},

{"letter":"y","data":["呀","已"]}
]"
