js中文汉字按拼音排序
JavaScript 提供本地化文字排序,比如对中文按照拼音排序,不需要程序显示比较字符串拼音。
String.prototype.localeCompare
在不考虑多音字的前提下,基本可以完美实现按照拼音排序。
在没有出现意外的情况下,各个支持 localeCompare 的浏览器都很正常。最近将 Chrome 更新到 58.0.3029.110,突然发现中文排序不正常。
确认之后是 localeCompare 需要明确指定 locales 参数.
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:
1 function pySegSort(arr,empty) { 2 if(!String.prototype.localeCompare) 3 return null; 4 5 var letters = "*abcdefghjklmnopqrstwxyz".split(''); 6 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(''); 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([
"我"
,
"不"
,
"懂"
,
"爱"
,
"啊"
,
"按"
,
"已"
,
"呀"
,
"选"
,
"县"
]))
//结果
