how to sort mixed numeric/alphanumeric array in javascript

Question

I have a mixed array that I need to sort by number, alphabet and then by digit-

[\'A1\', \'A10\', \'A11\', \'A12\', \'A3A\', \'A3B\', \'A3\', \'A4\', \'B10\', \'         


        

Answer 1

You could sort it with splitted array by type and check for equality first and then by type.

var array = ['A1', 'A10', 'A11', 'A12', 'A3A', 'A3B', 'A3', 'A4', 'B10', 'B2', 'F1', '1', '2', 'F3'];

array.sort(function (a, b) {
    var isNumber = function (v) { return (+v).toString() === v; },
        aa = a.match(/\d+|\D+/g),
        bb = b.match(/\d+|\D+/g),
        i = 0,
        l = Math.min(aa.length, bb.length);

    while (i < l && aa[i] === bb[i]) {
        i++;
    }
    if (i === l) {
        return aa.length - bb.length;
    }
    if (isNumber(aa[i]) && isNumber(bb[i])) {
        return aa[i] - bb[i];
    }
    return aa[i].localeCompare(bb[i]);
});

console.log(array);
