If you looking at how WordPress page, post page load fast using jQuery AJAX, no plugin request. There is an all details, how you implement to WordPress simply paste code correct location and boom website weather online server or local computer.
So the best approach here is just to create a post and publish it can auto work on whole website pages and the navigation menu. Whenever you see a loader animation after you have made some action on the page, it’s probably a jQuery AJAX request loading time to the server.
In this article, I’m going to guide you through the entire process of creating and handling jQuery AJAX loading. We will simply locate a simple code and file which will allow readers WordPress pages and post pages load without refresh on your website.
1. First Steps
Go to wp-content -> themes -> Your Theme Name -> CREATE FOLDER (any name ex: loader_boom).
Now this want to create file name ajax__loads.js
(function(window,undefined){ var History = window.History, $ = window.jQuery, document = window.document; if ( !History.enabled ) return false; $(function(){ var rootUrl = reload_helper['rootUrl'], contentSelector = '#' + reload_helper['container_id'], $content = $(contentSelector), contentNode = $content.get(0), $body = $(document.body), scrollOptions = { duration: 800, easing:'swing' }; if ( $content.length === 0 ) $content = $body; $.expr[':'].internal = function(obj, index, meta, stack){ var $this = $(obj), url = $this.attr('href')||'', isInternalLink; isInternalLink = url.substring(0,rootUrl.length) === rootUrl || url.indexOf(':') === -1; return isInternalLink; }; var documentHtml = function(html){ var result = String(html).replace(/<\!DOCTYPE[^>]*>/i, '') .replace(/<(html|head|body|title|script)([\s\>])/gi,'<div id="document-$1"$2') .replace(/<\/(html|head|body|title|script)\>/gi,'</div>'); return result; }; $.fn.wp_reload = function(){ var $this = $(this); $this.find('a:internal:not(.no-ajaxy,[href^="#"],[href*="wp-login"],[href*="wp-admin"])').on('click', function(event){ var $this = $(this), url = $this.attr('href'), title = $this.attr('title') || null; if ( event.which == 2 || event.metaKey ) return true; History.pushState(null,title,url); event.preventDefault(); return false; }); return $this; }; $body.wp_reload(); $(window).bind('statechange',function(){ var State = History.getState(), url = State.url, relativeUrl = url.replace(rootUrl,''); $.ajax({ url: url, success: function(data, textStatus, jqXHR){ var $data = $(documentHtml(data)), $dataBody = $data.find('#document-body:first ' + contentSelector), bodyClasses = $data.find('#document-body:first').attr('class'), contentHtml, $scripts; var $menu_list = $data.find('.' + reload_helper['mcdc']); jQuery('body').attr('class', bodyClasses); $scripts = $dataBody.find('#document-script'); if ( $scripts.length ) $scripts.detach(); contentHtml = $dataBody.html()||$data.html(); if ( !contentHtml ) { document.location.href = url; return false; } $content.stop(true,true); $content.html(contentHtml) .wp_reload() .css('text-align', '') .animate({opacity: 1, visibility: "visible"}); if ( '' != reload_helper['scrollTop'] ) { jQuery('html, body').animate({ scrollTop: jQuery(contentSelector).offset().top }, 1000); } $('.' + reload_helper['mcdc']).html($menu_list.html()); $body.wp_reload(); $(reload_helper['ids']).each(function(){ jQuery(this).addClass('no-ajaxy'); }); document.title = $data.find('#document-title:first').text(); try { document.getElementsByTagName('title')[0].innerHTML = document.title.replace('<','<') .replace('>','>') .replace(' & ',' & '); } catch ( Exception ) { } $scripts.each(function(){ var scriptText = $(this).html(); if ( '' != scriptText ) { scriptNode = document.createElement('script'); scriptNode.appendChild(document.createTextNode(scriptText)); contentNode.appendChild(scriptNode); } else { $.getScript( $(this).attr('src') ); } }); if ( typeof window.pageTracker !== 'undefined' ) window.pageTracker._trackPageview(relativeUrl); if ( typeof window.reinvigorate !== 'undefined' && typeof window.reinvigorate.ajax_track !== 'undefined' ) reinvigorate.ajax_track(url); }, error: function(jqXHR, textStatus, errorThrown){ document.location.href = url; return false; } }); }); }); })(window);2.

You can do this all WordPress website. It’s also a great way to optimize any heavy piece of the website which doesn’t have to be loaded right away, such as a big list of products in a drop-down. You can load them via jQuery AJAX just after follow these simple steps.
