Hi
Js Link is the new property for the spfield introduced in share point 2013,so you cant use it in SharePoint 2010
Hi,
According to your description, my understanding is that you want to know if JSLink can be used in SharePoint 2010.
Per my knowledge, JSLink is a new feature in SharePoint 2013, so SharePoint 2010 not supported JSLink.
If you want to use Client Rendering which similiar with JSLink in SharePoint 2010, you can use XSLT style sheet for Client rendering.
Here are some detailed articles for your reference:
Overview of XSLT List View Rendering System
How to: Customize the Rendering of a Field on a List View
Thanks
Best Regards
