Filtering

Filter and reset an Ajax Load More instance

In this example:

A custom menu will filter Ajax Load More between recent work and recent articles.

By utilizing Ajax Load More public and callback JavaScript functions you can create an intuitive filtering engine that adjusts shortcode parameters with the click of a button.

🔥  We’ve recently released the Filters add-on that makes filtering with Ajax Load More easier than ever!


HTML

Filtering is achieved by passing updated shortcode parameters as data attributes to the ajaxloadmore.filter public JavaScript function.

<div class="alm-filter-nav">
   <button data-repeater="template_8" data-post-type="portfolio" data-posts-per-page="3" data-scroll="false" data-button-label="More Work">Recent Work</button>
   <button data-repeater="default" data-post-type="post" data-posts-per-page="5" data-scroll="true" data-button-label="More Articles">Recent Articles</button>
</div>
HTML

Note: Shortcode parameters with underscores must be converted to dashes while using data attribute binding. e.g. post_type will be data-post-type.

JavaScript

The following code snippet should copied and placed inside your website JavaScript file.

/**
 * Filter button click event.
 */
function filterClick(event) {
	event.preventDefault();

	// Exit if button active.
	if (this.classList.contains('active')) {
		return;
	}

	// Get .active element.
	var activeEl = document.querySelector('.alm-filter-nav button.active');
	if (activeEl) {
		activeEl.classList.remove('active');
	}

	// Add active class.
	this.classList.add('active');

	// Set filter params
	var transition = 'fade';
	var speed = 250;
	var data = this.dataset;

	// Call core Ajax Load More `filter` function.
	// @see https://connekthq.local/plugins/ajax-load-more/docs/public-functions/#filter
	ajaxloadmore.filter(transition, speed, data);
}

// Get all filter buttons.
var filter_buttons = document.querySelectorAll('.alm-filter-nav button');
if (filter_buttons) {
	// Set initial active item.
	filter_buttons[0].classList.add('active');

	// Loop buttons.
	[].forEach.call(filter_buttons, function (button) {
		// Add button click event.
		button.addEventListener('click', filterClick);
	});
}
JavaScript

The following shortcode was used to create the Filtering example.

[ajax_load_more post_type="portfolio" scroll="false" posts_per_page="3" button_label="Load More Work"]

The following Template was used to create the Filtering example.
