如何在Drupal 8中更新我的视图而无需回到顶部？ [英] How to update my View in Drupal 8 without scrolling back to the top?

问题描述

我试图在Drupal 8中刷新我的视图，而不用以下代码重新加载页面：

I'm trying to refresh my View in Drupal 8 without reloading the page with this code :

(function ($, Drupal) {

  'use strict';

  setInterval(function() {
    $('.view-message-activity-stream-timeline-public').trigger('RefreshView');
  }, 10000);

})(jQuery, Drupal);

有效。

我的问题：

每次刷新视图时，该页面就会回到视图顶部。

Each time the view is refreshed, that page scolls back to the top of the view.

页面刷新还有另一个问题。当我单击主页底部的 Afficher plus链接时，第2页显示在第1页的下面，但是刷新页面后它将自动关闭。

There is another problem with the refresh of the page. When I click the "Afficher plus" link at the bottom of the home page, page 2 appears below page 1, but it automatically closes when the page is refreshed.

推荐答案

您的问题是由于 ViewAjaxController 将 ScrollTopCommand 加到每次加载/重新加载视图时，ajax响应。您可以在方法 ajaxView 中找到所涉及的行：

Your issue is caused by the ViewAjaxController adding up the ScrollTopCommand to the ajax response every time it loads/reloads a view. You can find the involved lines in the method ajaxView:

if (isset($pager_element)) {
  $response->addCommand(new ScrollTopCommand(".js-view-dom-id-$dom_id"));
  $view->displayHandlers->get($display_id)->setOption('pager_element', $pager_element);
}

希望可以通过以下方式更改发送给客户端的命令数据：执行 hook_ajax_render_alter ，只需删除 viewsScrollTop 命令，使其不再被触发：

Hopefully it is possible to alter the command data that is sent to the client by implementing the hook_ajax_render_alter, just remove the viewsScrollTop command so that it is no longer triggered:

function <MODULE>_ajax_render_alter(array &$data) {
  $view_name = '<view_name>';
  $view_dom_id = '<view_dom_id>';
  $selector = '.js-view-dom-id-' . $view_dom_id;

  foreach ($data as $key => $value) {
    if ($value['command'] === 'viewsScrollTop' && $value['selector'] === $selector) {
      unset ($data[$key]);
      break;
    }
  }
}

如果需要匹配 view_dom_id 与 view_name ，您可以搜索设置 $ data数组中的命令，例如。 $ cmd ['settings'] ['views'] ['ajaxViews'] 具有如下结构，请注意，数组键正是根据views_dom_id构建的：

If you need to match the view_dom_id with the view_name, you can search for the settings command in the $data array, eg. $cmd['settings']['views']['ajaxViews'] has a structure that looks like the following, note the array key precisely being built up from the views_dom_id :

[ajaxViews] => Array
    (
        [views_dom_id:<views_dom_id>] => Array
            (
                [view_name] => <view_name>
                [view_display_id] => <view_display_id>
                [view_dom_id] => <views_dom_id>
            )

    )
