javascript 中英文數組排序 sort結合localeCompare

var arr = new Array(6)
arr[0] = "a計划量余額";
arr[1] = "b計划發出";
arr[2] = "1計划量";
arr[3] = "強";
arr[4] = "采購倍數";
arr[5] = "計划收到";
arr[6] = "凈需求";
arr[7] = "毛需求";
arr[8] = "期初庫存";
arr[9] = "期末庫存";
arr[10] = "已經發出";
arr[11] = "已經收到";
arr[12] = "最小庫存";
arr[13] = "最小采購/生產量";
alert(arr.sort(function(a, b) {
return a.localeCompare(b)
}));
