Answer 1

If you want to make a non-focusable element focusable, you must add a tabindex attribute to it:

<div id="focusme" tabindex="1"></div>

Also, you can use the ID to reach it with the location hash. See the answer to your question here: Is it possible to focus on a <div> using javascript focus() function?

Answer 2

if you want to set focus to div through javascript you can use below code

$("#focusme").attr("tabindex",-1).focus();

Hope this helps you.

  $("#focusme").attr("tabindex",-1).focus(); 

 #focusme {width:400px; height:100px; overflow-y:scroll; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script> <div id="focusme"> focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me focus me </div>
