How to add multiple object ID to mongodb using vue.js

Question

This is code that I still working on, I intend to make auto increment which user can choose how many bulk/multiple serial number that he/she want to send. for example 1 serialNumber=123 if user choose 3 multiple value it will be 124,125,126 it will auto increment by +1.

                              item-value="customerId"
                              :item-text="
