Drupal and the latest jQuery

I need to use the latest version of jQuery in my Drupal.

jQuery update module is not enough because it doesn't update jquery to its latest version.

Is th开发者_开发问答ere anyway to use the latest version of jquery in the front-end, and the drupal included version for the back-end ?

Should I work on the theme templates files ? Is this going to cause issues ?

thanks

Drupal includes the jQuery library in each page that uses JavaScript. The only way to use a more recent version of jQuery than the one Drupal comes with is to install jQuery Update, which provides also a script for compatibility with scripts using an older version of the library. The jQuery Update module updates:

• Drupal 5 to jQuery 1.2.6
• Drupal 6 to jQuery 1.3.2
• Drupal 7 to jQuery 1.5.2, and jQuery UI 1.8.11

If you are going to simply replace the jQuery library contained in /misc, then Drupal scripts will stop to work (I tried doing that, and that was the result). Loading a more recent version after Drupal loaded the library in /misc will also cause problems.

To complete the information, there was a module that came with its own version of the jQuery library that was then binded to $ui; in that way, other code would still use the default jQuery library, while your module / theme would use the more recent library. The module simply loaded its own version of jQuery, and then executed the following JavaScript line:

window.$ui = jQuery.noConflict(true);

Using the same approach, you would be able to load the latest version of jQuery without creating any conflict with existing modules. This system doesn't work if you are using a module developed from somebody else, and that uses Javascript code that uses $; it works for your custom module/theme you run on your site, though.

Yes you can using jquery update (if you need jQuery 1.8 use the dev version) and a code like that in a module to switch version for front end and backend.

/**
 * Implements hook_module_implements_alter().
 */
function mymodule_site_module_implements_alter(&$implementations, $hook) {
  if ($hook == 'library_alter') {
    if(isset($implementations['jquery_update'])) {
      // Move jquery update to the end. This will make sure our hook_library_alter
      // is always called before the jquery_update.
      $jquery_update = $implementations['jquery_update'];
      unset($implementations['jquery_update']);
      $implementations['jquery_update'] = $jquery_update;
    }
  }
}

/**
 * Implements hook_library_alter().
 */
function mymodule_site_library_alter(&$libraries, $module) {
  // If it is the admin theme all we want to do is change the global $conf
  // variable so when jquery_update runs right after us it will use 1.5.
  // We are not using path_is_admin(current_path()) because some admin path can use
  // the frontend theme like node edit page
  global $theme_key;
  if (variable_get('admin_theme') == $theme_key) {
    // Modifying global $conf variable, can be dangerous. Be carefull.
    global $conf;
    $conf['jquery_update_jquery_version'] = '1.5';
  }
}

I write a blog post about it http://antistatique.net/blog/2013/01/04/drupal-use-a-different-jquerys-version-for-the-frontend-and-backend/ .

Are you using separate themes for front-end and back-end? You can probably add some code to the themename_preprocess_page() function in the front-end's template.php to replace the jquery files in that theme only.

What about using jQuery.noConflict()? I don't know of any concrete examples of Drupal modules that work in jQuery 1.2/1.3 but break in 1.4 to test this, but ostensibly loading jQuery 1.4 after Drupal loads jQuery 1.2/1.3 (so, add it to your theme) and using var jNew = jQuery.noConflict() would pass $() back to the jQuery most of Drupal expects, and allow you to use jNew() to do the jQuery 1.4 stuff you need to do.

For the front-end I did something "bad", but it works.

I included the latest jQuery

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">$.browser = {msie: false}; // fix for scripts that use that property</script>

disabled the drupal's jQuery

<?php print str_replace(
    '<script type="text/javascript" src="/misc/jquery.js', 
    '<script no-drupal-jquery="', 
    $scripts
);
?>

and I get

<script no-drupal-jquery="?W"></script>
<script ...
