This emulates behavior of tab and shifttab with → and ←.

I.e., switch focus to the next/previous select field with parent class .tab (which are not siblings in the DOM.)

It works, but is there any way to make it more elegant? Especially the if/then and the limit to range. I'm fairly new to JavaScript.

$(document).on('keydown', '.tab select', function (e) 
 let tabs = $(".tab select"); //get all tabs
 let tab = tabs.index($($(document.activeElement))); //focused tab
 if (e.which == 37) //left arrow
 tab -= 1;
 else 
 if (e.which == 39) //right arrow
 tab += 1;
 
 ;
 tab = Math.min(tabs.length, Math.max(tab, 0)); //stay in range
 tabs.eq(tab).focus()
);
