javascript sort with unicode
提问by Andrej Kaurin
There are a lot of examples for sorting some JSON array by some property (i.e. 'title') We are using compare function like this one:
有很多示例可以按某些属性（即“标题”）对一些 JSON 数组进行排序，我们正在使用这样的比较函数：
function sortComparer(a, b) {
if (a.title == b.title)
return 0;
return a1 > b1 ? 1 : -1;
}
Problem is that Serbian Latin alphabet order looks like "A, B, C, ?, ?, D,..." When using sortComparer above I am getting D sorted before "?" or "?". Any idea how to sort respecting current culture language?
问题是塞尔维亚拉丁字母顺序看起来像“A，B，C，？，？，D，...” 当使用上面的 sortComparer 时，我将 D 排在“？”之前。或者 ”？”。任何想法如何排序尊重当前的文化语言？

If the locale in your system is set correctly then you can use localeComparemethod instead of greater-thanoperator to compare the strings - this method is locale aware.
如果您系统中的语言环境设置正确，那么您可以使用localeComparemethod 而不是大于运算符来比较字符串 - 此方法是语言环境感知的。
function sortComparer(a,b){
return a.title.localeCompare(b.title)
};

For sorting an array with custom setting do as following:
要使用自定义设置对数组进行排序，请执行以下操作：
Create an array with a custom order of alphabets:
var alphabets = ["A", "B", "C", "?", "?", "D","D?","?","E","F","G","H","I","J","K","L","Lj","M","N","Nj","O","P","R","S", "??","T","U","V","Z","?"];Create a list of test array:
var testArrray = ["B2","D6","A1","?5","?4","C3"];Create a sort function name:
function OrderFunc(){ testArrray.sort(function (a, b) { return CharCompare(a, b, 0); }); }create the CharCompare function(index: sort "AAAB" before "AAAC"):
function CharCompare(a, b, index) { if (index == a.length || index == b.length) return 0; //toUpperCase: isn't case sensitive var aChar = alphabets.indexOf(a.toUpperCase().charAt(index)); var bChar = alphabets.indexOf(b.toUpperCase().charAt(index)); if (aChar != bChar) return aChar - bChar else return CharCompare(a,b,index+1)}
Call OrderFunc for sorting the testArray(the result will be : A1,B2,C3,?4,?5,D6).
创建一个具有自定义字母顺序的数组：
var alphabets = ["A", "B", "C", "?", "?", "D","D?","?","E","F","G","H","I","J","K","L","Lj","M","N","Nj","O","P","R","S", "??","T","U","V","Z","?"];创建测试数组的列表：
var testArrray = ["B2","D6","A1","?5","?4","C3"];创建排序函数名称：
function OrderFunc(){ testArrray.sort(function (a, b) { return CharCompare(a, b, 0); }); }创建 CharCompare 函数（索引：在“AAAC”之前排序“AAAB”）：
function CharCompare(a, b, index) { if (index == a.length || index == b.length) return 0; //toUpperCase: isn't case sensitive var aChar = alphabets.indexOf(a.toUpperCase().charAt(index)); var bChar = alphabets.indexOf(b.toUpperCase().charAt(index)); if (aChar != bChar) return aChar - bChar else return CharCompare(a,b,index+1)}
调用 OrderFunc 对 testArray 进行排序（结果将是：A1,B2,C3,?4,?5,D6）。
Good Luck
祝你好运

Use The Intl.Collator like you will get perfect sorting result
使用 Intl.Collator 就像你会得到完美的排序结果
function letterSort(lang, letters) {
letters.sort(new Intl.Collator(lang).compare);
return letters;
}
console.log(letterSort('gu', ['?','?','?']));
// expected output: Array ["a", "?", "z"]
console.log(letterSort('sv', ['a','z','?']));
// expected output: Array ["a", "z", "?"]
