configuring jquery_update to use jquery via Google CDN?

2 things....

First, be aware that not everyone has access to the js in the google cdn. There are some countries (like Iran) that block it.

Second, Drupal 6 core doesn't support external JavaScripts. It may be possible to support this with a hack of sorts.

This can go on the mid term todo list. But, before you pursue this re-read the first point and consider what your site will be like when js breaks for people in those countries.

hi,

understood.

i did not realize that ... i note that . e,g, yui-editor module allows use of external js ... does it not touch core as well?

thanks!

drupal_add_js(), which is the function a module should use to add a reference to a JavaScript file into the page, doesn't allow to use a reference to a file that is not on the local server that is running Drupal.

I too need this - the biggest reason is that the jQuery folks themselves request this, so that it will be more likely to be cached from other sites and thus speed up the user's browsing experience, rather than re-downloading multiple jquery.js files from various websites that all have the same source. It's becoming one of the most heavily used libraries out there, especially given its inclusion in many CMSes, so this seems like a great idea...

Any ideas?

This would be a great addition.

One thought - due to Drupal's aggregation if cache is enabled, this would need to be outside of that to do any good (ie: to allow it to be cached on the client across sites)

The attached patch to 6.x-2.x-dev accomplishes the following:

• provides an additional option to use "Google CDN (External, Minified, Compressed)"
• updates to supporting functions to handle the new options
• adds a script tag for http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js - does not add this using drupal_add_js
  • added before any other scripts
  • it is not included in aggregation

Is it a little hacky? Yes.. but it works as expected and takes the load off of your server using a free CDN.
Comment if anyone has a better way of accomplishing this.
