字符串單個替換

項目中遇到的問題，要把‘1111100’變成‘週一，週二，週三，週四，週五’。

vm.ruleList = [{
                    "alarmruleId": "222",
                    "alarmruleName": "上學校門出入規則",

                vm.arr = ['週一', '週二', '週三', '週四', '週五', '週六', '週日'];
                for (var i = 0; i < vm.ruleList.length; i++) {
                    if (vm.ruleList[i].alarmruleinfo.timeType == 0) {
                        vm.ruleList[i].alarmruleinfo.dateRepeat = [];
                        for (var j = 0; j < 7; j++) {
                            vm.ruleList[i].alarmruleinfo.timeRepeat.charAt(j) === '0' ? '' : vm.ruleList[i].alarmruleinfo.dateRepeat.push(vm.arr[j]);
                        }
                        vm.ruleList[i].alarmruleinfo.dateRepeat = vm.ruleList[i].alarmruleinfo.dateRepeat.join(',');

                    }
                }

                $log.log(vm.ruleList)

 

耶！
