how to control redirecting to classic from lightning detail page?

General flow:
I have one object.
From that object i have created a "Create Record" custom javascript button in the related list(self lookup). 
When i was click on the "Create Record" button it will redirected to the new record creation page.
after saving the record it will redirected to the previous detail page and the record will in the related list.
working fine in classic.

issue in lightning view:
if i login into the lighning, click on "create Record " button it will redirected to the record creation page (i.e in classic view), but it should be in a lightning view only.

can you please suggest on this issue.

thanks in advance

Hi,

I trust you are doing very well.

It is an Idea (https://success.salesforce.com/ideaView?id=08730000000cGX8AAM) to support Javascript Buttons in Lightning Experience.

However, you can use Lightning Experience Configuration Converter to convert JavaScript buttons to lightning. Please refer to the below links which might help you further with the above issue.

There are other options also to replace the javascript button in lightning. You can use Quick Actions, Custom Buttons, or Apex. Go through this trailhead module to understand the alternatives available:
