Today I will talk about the JsLink we use to make custom displays in our good old classic 2013 interface.
A typical example is the following
In this example, we change the rendering of the “AssignedTo” field with a custom html of our own.
This example can sometimes be too much for simple requests such as “I want to display this field in Read-Only”.
To do this, you can use the default SharePoint rendering!
I want to thank the person who took time to compile this really useful information!
For my part, my source is the following: https://sharepoint.stackexchange.com/questions/112506/sharepoint-2013-js-link-return-default-field-rendering
Hoping this helps !
