JavaScript Filtering | Examples

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.

<button type="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 type="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>

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

/**

* @param {*} 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.com/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);

});

}

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"]
