用点、字母、数字对对象数组进行排序。我能够按数字排序，但混合值很困难。不确定是否可以做对

我尝试了典型的排序功能并检查项目是否为字符串。但我得到了一个非常奇怪的输出。尝试了多种不同的方法。

 var arr = [{section: '12.2.a'},
               {section: '12.2.b.iii'},
               {section: '12.2.c'},
               {section: '12'},
               {section: '12A'},
               {section: '12.3.b'},
               {section: '12.3.c'},
               {section: 'Q2'},
               {section: 'Q32'},
               {section: 'Q6'},
               {section: 'Q5'}]



var arr2 = arr.sort(function(a, b) {
    var nums1 = a.section.split(".");
    var nums2 = b.section.split(".");

    for (var i = 0; i < nums1.length; i++) {
      if (nums2[i]) {
        if (nums1[i] !== nums2[i]) {
          if (isNaN(parseInt(nums1[i])) && isNaN(parseInt(nums2[i]))) {
            return nums1[i].localeCompare(nums2[i]);
          }
          return parseInt(nums1[i]) - parseInt(nums2[i]);   
        }
      } else {
        return 1;
      }
    }
    return -1;
});

我应该使用 localeCompare 还是可以不使用？ 希望输出为：

[
 {section: '12'},
 {section: '12A'},
 {section: '12.2.a'},
 {section: '12.2.b.iii'},
 {section: '12.2.c'},
 {section: '12.3.b'},
 {section: '12.3.c'},
 {section: 'Q2'},
 {section: 'Q6'},
 {section: 'Q5'}
 {section: 'Q32'}]

非常感谢任何建议

我提出了一种完全不同的方法。我们将修改您的字符串，直到它们可以排序localeCompare

就是这样：

// "12" sorts before "2", prefixing to "12" and "02" fixes this
// (length should be bigger than your largest nr)
var makeLength5 = prefixWithZero.bind(null, 5);

// This function generates a string that is sortable by localeCompare
var toSortableString = function(obj) {
  return obj.section
    .replace(/\./g, "z")            // Places `12A` before `12.` but after `12`
    .replace(/\d+/g, makeLength5);  // Makes every number the same length
};

var arr = [{section:"12.2.a"},{section:"12.2.b.iii"},{section:"12.2.c"},{section:"12"},{section:"12A"},{section:"12.3.b"},{section:"12.3.c"},{section:"Q2"},{section:"Q32"},{section:"Q6"},{section:"Q5"}];
var arr2 = arr.sort(function(a, b) {
  return toSortableString(a).localeCompare(toSortableString(b));
});

console.log(JSON.stringify(arr2.map(function(s){ return s.section; }), null, 2));

// Helper methods
function prefixWithZero(length, str) {
  while (str.length < length) {
    str = "0" + str;
  }
  return str;
};
