I have 2 asp-route-id values as below:

  <a class="btn btn-block btn-primary" asp-controller="Sales" asp-action="Data" asp-route-sales_pid="0" asp-route-users_pid="users_pid">New</a>

the above is used for a new sales transaction, when it clicked, I expect to set asp-route-users_pid with current users_pid.

how to archive this with javascript?
