[js] 基于字符串中的数字进行字符串排序

#1

            function order(words) {
                return words.split(' ').sort((a, b) => a.match(/\d/) - b.match(/\d/)).join(' ');
            }

#2

            function order(words) {
                return words.split(" ").sort((a, b) => a.replace(/[^\d]/g, "") - b.replace(/[^\d]/g, "")).join(" ")
            }

#3

            function order(words) {
                var reg = /[^\d]+/g,
                    original = words.split(' '),
                    correlation = [],
                    reorder = [];
                if (words === '') {
                    return words;
                }
                original.forEach(function(ele, index) {
                    correlation[index] = {};
                    correlation[index]['i'] = index;
                    correlation[index]['v'] = Number(ele.replace(reg, ''));
                });
                correlation.sort(function(a, b) {
                    return a.v - b.v;
                });
                correlation.forEach(function(ele, index) {
                    reorder.push(original[ele.i]);
                });
                return reorder.join(' ');
            }

#test

            console.log(order("is2 Thi1s T4est 3a"));
            console.log(order("4of Fo1r pe6ople g3ood th5e the2"));
            console.log(order(""));
