JavaScript provides localized text sorting, such as sorting Chinese according to pinyin, without the need for programs to display and compare the pinyin of strings.
String.prototype.localeCompare Under the premise of not considering polyphonic words, the sorting according to pinyin can basically be perfectly realized.
Every browser that supports localeCompare works fine, without exception. Recently updated Chrome to 58.0.3029.110, and suddenly found that the Chinese sorting is not normal.
After confirmation, localeCompare needs to specify the locales parameter explicitly.
Code 1, Pinyin sorting:
var array = ['Wuhan', 'Beijing', 'Shanghai', 'Tianjin'];
var resultArray = array.sort(
function compareFunction(param1, param2) {
return param1.localeCompare(param2,"zh");
}
);
console.log(resultArray);
Firefox browser resultArray result is: [ 'Beijing' , 'Shanghai' , 'Tianjin' , 'Wuhan' ] ;
Code 2, Pinyin sort and alphabetical:
1 function pySegSort(arr,empty) {
2 if(!String.prototype.localeCompare)
3 return null;
4
5 var letters = "*abcdefghjklmnopqrstwxyz".split('');
6 var zh = "Abahadahahahahahaaaaaaaaaaaaaaaaaaaaaaaaaa".split('');
7
8 var segs = [];
9 var curr;
10 $.each(letters, function(i){
11 curr = {letter: this, data:[]};
12 $.each(arr, function() {
13 if((!zh[i-1] || zh[i-1].localeCompare(this,"zh") <= 0) && this.localeCompare(zh[i],"zh") == -1) {
14 curr.data.push(this);
15 }
16 });
17 if(empty || curr.data.length) {
18 segs.push(curr);
19 curr.data.sort(function(a,b){
20 return a.localeCompare(b,"zh");
21 });
22 }
23 });
24 return segs;
25 }
JSON.stringify(pySegSort([
