jQuery add text to span when div is visible - 


<div class="box"> <span class="test"></span> </div> <div class="row"></div> <input type="button" value="add" id="button">  <style type="text/css">     .box {         display: none;      } </style>

above div not visible when page load. making div visible after button click. want append text span when div visible.

$('#button').on("click",function(e){    e.preventdefault();    $('.box').clone().show().append('.row'); });

i tried 

1) $(".box").closest(".test").text("hello"); 2) $(".box").find(".test").text("hello");

but not adding text span.

try :

$(document).ready(function(){       $("button").on("click",function(){           $(".box").find(".test").text("hello");           $(".box").show(500);       })   })

final code :

<!doctype html>  <html lang="en">  <head>            <style type="text/css">          .box {              display: none;           }      </style>        </head>      <body>                    <div class="box">              <span class="test"></span>          </div>          <div class="row"></div>                    <button>show div</button>          <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>          <script>                        $(document).ready(function(){                 $("button").on("click",function(){                     $(".box").find(".test").text("hello");                     $(".box").show(500);                 })             })             </script>      </body>  </html>
