You can set a localStorage item when a user clicks the button, and on page load look for the localStorage item and conditionally show the hidden div.
var $hidden = $('.hidden'); localStorage.getItem('show') && $hidden.show(); $('button').on('click',function() { localStorage.setItem('show',true); window.location.reload(false); })
.hidden { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="hidden">hidden</div> <button>click</button>

First, if your requirement is to have a button be clicked, you'll need a button, not a paragraph.
Next, instead of the visibility property (which still allocates space on the page for the element even when it is not shown), use display (which does not).
Most importantly, if you reload the document, then any local variables you have will be lost. You need to persist some kind of "flag" between page loads. This can be done in a variety of ways (cookies, sessionStorage, localStorage, server-side), but localStorage is probably the simplest.
This code won't actually run, here in the Stack Overflow snippet environment due to sandboxing, but you can see a working version of it here .
See other comments inline:
$(document).ready(function(){ // Check to see if this is a page reload or not by seeing if a value was placed // into localStorage from a previous page load if(localStorage.getItem("loadedEarlier")){ // Page has already loaded earlier $("#test2").css("display","block"); } $("#btn").click(function(){ location.reload(); }); // Place a value into localStorage localStorage.setItem("loadedEarlier", "yes") });
/* No need for JavaScript to initially hide the element which can cause the usre to see it momentarially before the JS runs. Set its default display to none instead. */ #test2 { display:none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="btn">Click to Reload</button> <div id="test2"><p id="p2">this is invisible text</p></div>
