ajax_link

The ajax link module give tools for themers and developers to easily implements ajax links.

Core implements AjaxResponse methods, but if you already have a page with content you want to append or replace in an area, you have to define custom AjaxResponse to each cases.

This module implements a generic AjaxResponse which load and render page accessible by the link you click on, and only respond with the markup of the array to replace.

Nothing to configure from the UI, everything happens by data attributes on the links, so it's easy to access for themers.

The ajax_link/ajaxLink library needs to be attached on pages where you want to use ajax link.

Example :

I want to load the next page of the product list in the area matching the class products-list.
Define the link as an ajax link adding 'ajax-link' class to the link markup.
Add the 'data-ajax-link-selector' data attribute with css selector where to find and replace content : '.products-list'.
<a href="{{ url }}" class="ajax-link" data-ajax-link-selector=".products-list">This is an ajax link</a>

And in preprocess :

$variables['#attached']['library'][] = 'ajax_link/ajaxLink';

or twig :
{{ attach_library('ajax_link/ajaxLink') }}

Here is available settings for the link :
