JS method to sort Chinese characters by pinyin

This article mainly introduces the method of JS to sort Chinese characters by pinyin, involving JavaScript conversion, traversal, sorting and other related operation skills for Chinese strings. Friends who need it can refer to it. I hope it can help everyone.

Code 1, Pinyin sorting:

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);

Firefox resultArray The result is:

[ '北京' , '上海' , '天津' ,'武汉' ] ;

Code 2, sorted by pinyin and sorted alphabetically:

function pySegSort(arr,empty) {
 if(!String.prototype.localeCompare)
  return null;
 var letters = "*abcdefghjklmnopqrstwxyz".split('');
 var zh = "阿八嚓哒妸发旮哈讥咔垃痳拏噢妑七呥扨它穵夕丫帀".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"]))

Result:

"[
　　{"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"]}
]"
