javascript - 如何按对象字符串值之一对对象数组进行数字排序？

Question

我有一个与此类似的对象数组:

 var this array = [
    { 
    "id" : "A20",
    "age" : "16"
    },
    {
    "id" : "A2",
    "age" : "12"
    },
    { 
    "id" : "B16",
    "age" : "45"
    }]

我需要按 ID 对这个数组进行排序，所以它最终会像这样:

this array = [
        { 
        "id" : "A2",
        "age" : "12"
        },
        {
        "id" : "A20",
        "age" : "16"
        },
        { 
        "id" : "B16",
        "age" : "45"
        }]

我有这种排序方法:

nodes.sort(function(a,b){
    // console.log(a.Pos)
    // console.log(a.pinNum)
    var alc = a.id, blc = b.id;
    console.log(alc)
    return alc > blc ? 1 : alc < blc ? -1 : 0;
    });

但这只能按字母顺序工作。我也发现了这个，但它只返回我传递给函数的字符串，而不是对象数组:

function sortArray(arr) {
        var tempArr = [],
        n;
        console.log(arr)
        for (var i in arr) {

            var thisString = arr[i].id;

            // tempArr[i] = arr[i].match(/([^0-9]+)|([0-9]+)/g);
            tempArr[i] = thisString.match(/([^0-9]+)|([0-9]+)/g);
            for (var j in tempArr[i]) {
                if (!isNaN(n = parseInt(tempArr[i][j]))) {
                    tempArr[i][j] = n;
                }
            }
        }
        tempArr.sort(function (x, y) {
            for (var i in x) {
                if (y.length < i || x[i] < y[i]) {
                    return -1; // x is longer
                }
                if (x[i] > y[i]) {
                    return 1;
                }
            }
            return 0;
        });
        for (var i in tempArr) {
            arr[i] = tempArr[i].join('');
        }
        return arr;
    }
    console.log(sortArray(nodes).join(","));

我需要的是第二个排序功能，但能够按字母顺序和数字顺序排序。谢谢

var array = [{ 
   "id" : "A20",
   "age" : "16"
}, {
   "id" : "A2",
   "age" : "12"
}, { 
   "id" : "B16",
   "age" : "45"
}];

array.sort(function(a, b) {
 var aSplit = /(\D*)(\d*)/.exec(a.id),
     bSplit = /(\D*)(\d*)/.exec(b.id);

 if( aSplit[1] !== bSplit[1] )
    return aSplit[1].localeCompare(bSplit[1]);
 else
    return aSplit[2] - bSplit[2];
});
