特定页面上的 drupal jQuery 1.4 [英] drupal jQuery 1.4 on specific pages

问题描述

我正在寻找一种方法来强制 drupal 在特定页面上使用 1.4.

I'm looking for a way to force drupal to use 1.4 on specific pages.

这与这个老问题相同:特定页面上的drupal jQuery 1.4

我花了一段时间来尝试我标记为正确的答案.但是因为我是模块开发的新手，所以我无法根据答案弄清楚.

It look me a while to try the answer which I marked correct. But because I'm new to module dev overall I couldn't figure it out based on the answer.

该答案中的代码如下所示:

The code from that answer looked like this:

/**
 * 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);
    }
  }
}

我需要在博客"和视频"的节点类型上取消设置 jquery_update 1.3.2.有人可以帮我吗?

I need the jquery_update 1.3.2 to be unset on the node-types of 'blog' and 'video'. Can someone help me out?

谢谢.

推荐答案

在 MYMODULE_preprocess_page 函数中，$scripts 变量包含一个数组，其中包含将添加到页面的所有 JavaScript 的信息.

In the MYMODULE_preprocess_page function, the $scripts variable contains an array with the information about all JavaScript that will be added to the page.

如果你想从页面中删除一个 JS 文件，你应该从 $scripts 数组中删除它的条目(然后更新 $variables['scripts']).这就是 unset 函数所做的.

If you want to remove a JS file from the page, you should remove its entry from the $scripts array (and then update $variables['scripts']). That's what the unset function is doing .

如果您要删除的 jQuery 是 Drupal 附带的 jQuery，您可以使用以下命令删除它:

If the jQuery you're trying to remove is the one that's shipped with Drupal, you can remove it with:

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

否则，您必须print_r $scripts 变量才能找到您需要删除的条目.

Otherwise, you'll have to print_r the $scripts var in order to find the entry you need to remove.
