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。

在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。
