The first element is // view_array. However, view_array does not get set anywhere, but since we do // have access to the View object, we can also access the View object's // element, which is a render element that does have #contextual_links set if // the display supports it. Doing this allows contextual_preprocess() to // access this theme hook's render element, and therefore allows this template // to have contextual links. // @see views_theme() $variables['view_array'] = $variables['view']->element; // Attachments are always updated with the outer view, never by themselves, // so they do not have dom ids. if (empty($view->is_attachment)) { // Our JavaScript needs to have some means to find the HTML belonging to // this view. // // It is true that the DIV wrapper has classes denoting the name of the view // and its display ID, but this is not enough to unequivocally match a view // with its HTML, because one view may appear several times on the page. So // we set up a hash with the current time, $dom_id, to issue a "unique" // identifier for each view. This identifier is written to both // drupalSettings and the DIV wrapper. $variables['dom_id'] = $view->dom_id; }} |
