function views_ui_add_ajax_wrapper($element, FormStateInterface $form_state) { // Find the region of the complete form that needs to be refreshed by AJAX. // This was earlier stored in a property on the element. $complete_form = &$form_state->getCompleteForm(); $refresh_parents = $element['#views_ui_ajax_data']['refresh_parents']; $refresh_element = NestedArray::getValue($complete_form, $refresh_parents); // The HTML ID that AJAX expects was also stored in a property on the // element, so use that information to insert the wrapper <div> here. $id = $element['#views_ui_ajax_data']['wrapper']; $refresh_element += array( '#prefix' => '', '#suffix' => '', ); $refresh_element['#prefix'] = '<div id="' . $id . '" class="views-ui-ajax-wrapper">' . $refresh_element['#prefix']; $refresh_element['#suffix'] .= '</div>'; // Copy the element that needs to be refreshed back into the form, with our // modifications to it.
