特定页面上的drupal jQuery 1.4

标签: jquery drupal drupal-modules

我正在寻找一种强制drupal在特定页面上使用1.4的方法。

这与旧问题相同:drupal jQuery 1.4 on specific pages

我想看一下我标记为正确的答案。但是因为我是模块开发人员的新手,所以根据答案我无法弄明白。

该答案的代码如下:

/**
 * Implementation of hook_theme_registry_alter().
 * Based on the jquery_update module.
 *
 * Make this page preprocess function runs *last*,
 * so that a theme can't call drupal_get_js().
 */
function MYMODULE_theme_registry_alter(&$theme_registry) {
  if (isset($theme_registry['page'])) {
    // See if our preprocess function is loaded, if so remove it.
    if ($key = array_search('MYMODULE_preprocess_page', 
      $theme_registry['page']['preprocess functions'])) {
      unset($theme_registry['page']['preprocess functions'][$key]);
    }
    // Now add it on at the end of the array so that it runs last.
    $theme_registry['page']['preprocess functions'][] = 'MYMODULE_preprocess_page';
  } 
}

/**
 * Implementation of moduleName_preprocess_hook().
 * Based on the jquery_update module functions.  *
 * Strips out JS and CSS for a path.
 */
function MYMODULE_preprocess_page(&$variables, $arg = 'my_page', $delta=0) {

  // I needed a one hit wonder. Can be altered to use function arguments
  // to increase it's flexibility.
  if(arg($delta) == $arg) {
    $scripts = drupal_add_js();
    $css = drupal_add_css();
    // Only do this for pages that have JavaScript on them.
    if (!empty($variables['scripts'])) {
      $path = drupal_get_path('module', 'admin_menu');
      unset($scripts['module'][$path . '/admin_menu.js']);
      $variables['scripts'] = drupal_get_js('header', $scripts);
    }
    // Similar process for CSS but there are 2 Css realted variables.
    //  $variables['css'] and $variables['styles'] are both used.
    if (!empty($variables['css'])) {
      $path = drupal_get_path('module', 'admin_menu');
      unset($css['all']['module'][$path . '/admin_menu.css']);
      unset($css['all']['module'][$path . '/admin_menu.color.css']);
      $variables['styles'] = drupal_get_css($css);
    }
  }
}

我需要在'blog'和'video'的节点类型上取消设置jquery_update 1.3.2。有人可以帮助我吗?

谢谢。

MYMODULE_preprocess_page函数中,$ scripts变量包含一个数组,其中包含有关将添加到页面的所有JavaScript的信息。

如果要从页面中删除JS文件,则应从$ scripts数组中删除其条目(然后更新$ variables ['scripts'])。这就是unset函数正在做的事情。

如果您尝试删除的jQuery是Drupal附带的jQuery,您可以使用以下命令将其删除:

unset($scripts['core']['misc/jquery.js']);

否则,您必须print_r $ scripts var才能找到需要删除的条目。
