How to Load a WordPress Page Without Refreshing Using jQuery Ajax

If you’re looking to achieve fast page loading for WordPress pages without refreshing using jQuery AJAX, and you prefer not to use plugins, you’re in luck. I will provide you with all the necessary details on how to implement this feature in WordPress. By simply copying and pasting the provided code into the correct location, your website will load quickly, whether it’s hosted on a server or running locally on your computer.

The optimal approach in this case is to create a post and publish it, as it will automatically work on all website pages and the navigation menu. Whenever you encounter a loader animation after performing an action on the page, it indicates that a jQuery AJAX request is being sent to the server, which affects the loading time.

In this comprehensive article, I will guide you through the step-by-step process of creating and managing jQuery AJAX loading for WordPress pages and post pages. By implementing a simple code snippet and file, you will enable seamless loading without the need to refresh your website. This feature will greatly enhance the user experience for your readers.

Step 1: Getting Started

To begin, navigate to the following directory: wp-content -> themes -> Your Theme Name. Inside your theme’s folder, create a new folder with any desired name (e.g., “loader_boom”). This folder will be used to store the necessary files for implementing the loader functionality.

Next, create a file named “ajax_loads.js”. This JavaScript file will be responsible for handling the AJAX loading functionality on your WordPress site.

(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('<','&lt;') .replace('>','&gt;') .replace(' & ',' &amp; '); } 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);

Step 2: Creating an Additional File named “ajax_history.js”

In addition to the “ajax_loads.js” file, create another file called “ajax_history.js”. This JavaScript file will be utilized to manage the history of AJAX requests on your WordPress site.

Step 3: Modifying the “header.php” File in Your WordPress Theme

To proceed, log in to your WordPress admin panel and navigate to “Appearance” -> “Theme Editor”. In the Theme Editor, locate and select the “header.php” file. Inside this file, paste the provided code. This code snippet will be responsible for including the necessary JavaScript files and initiating the AJAX loading functionality on your website.

<script type='text/javascript' src='<?php echo get_template_directory_uri(); ?>/loader_boom/ajax__history.js?ver=5.3.2'></script>
<script type='text/javascript' src='<?php echo get_template_directory_uri(); ?>/loader_boom/ajax__loads.js?ver=5.3.2'></script>
<script> var reload_helper = {"rootUrl":"http:\/\/<?php echo $_SERVER['HTTP_HOST']; ?>\/\/","ids":"","container_id":"main","mcdc":"menu","searchID":"searchform","transition":"","scrollTop":"","loader":"","bp_status":""}; </script>

I trust that this guide has provided you with a solid foundation for creating your own “without-page-refresh” solutions. This method is applicable to any WordPress website and offers an excellent approach to optimize resource-heavy components that don’t need to be loaded immediately, such as a sizable dropdown list of products. By following these straightforward steps, you can effortlessly load these components using jQuery AJAX.
