Answer 1

Working Demo

 $(".visitlink.item span").click(function() { $(this).closest(".coursebox").find(".summary.item").toggleClass("disNone"); $(this).closest(".coursebox").find(".fullsum.item").toggleClass("disBlock"); }); 

 .disNone { display: none; } .disBlock { display: block; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="wrapper"> <div class="coursebox"> <div class="summary item">summary</div> <div class="fullsum item">fullsum</div> <div class="visitlink item"><span>Readmore</span> </div> </div> <div class="coursebox"> <div class="summary item">summary</div> <div class="fullsum item">fullsum</div> <div class="visitlink item"><span>Readmore</span> </div> </div> </div> 

Answer 2

You can change to

 $(this).parent().siblings(".summary.item").toggleClass("disNone");
 $(this).parent().siblings(".fullSum.item").toggleClass("disBlock");

As the clicked element is span element and the target elements are the siblings of it's parent div.
