How to change order of javascript files in Drupal 6?

Question

I would like to change the order of my javascript files, and specifically move the jwplayer.js file so that it gets included after the jquery_ui*.js files. Does anyone know how to do this? I see how to do this in Drupal 7, using hook_js_alter(). But I do not see how to do this in Drupal 6.

UPDATE: Here is some more information on my setup, that might be relevant: - I call drupal_add_js('jwplayer.js') from within a custom views template. The template adds jwplayer.js conditionally, depending on whether the views data includes any videos.

Answer 1

If you look at drupal_add_js() and drupal_get_js(), you will see the details. Unfortunately, module_invoke_all() or it's cousins, don't get called, which means there are no hooks. Boo. A related issue is that when you aggregate, you loose the ability to do string manipulation (eg, explode, reorder, implode).

The best way to handle this is to alter the weight of the JW Player Module. One way to do this is to edit the {system} table and edit the weight column value. With the weights, lower numbers run earlier, higher numbers later, and where there is a tie, they run alphabetically. Make sure you clear cache when you do this. See Change module's weight - by module or manualy for some more details.

If this doesn't fix the problem, then the JS files aren't being added by the same hook. I am not sure what can be done it in this case w/o hacking the module.

A total sledgehammer approach would be to not include the your code, but to add it in the theme's .info file. This should add it after all modules.

I think you need to unset and attached it again in the order you prepared. See my post here which is a bit similar - How can I remove Javascript files?

Answer 3

JS Alter module for D6: http://drupal.org/project/jsalter

This module adds a hook_js_alter() hook that other modules can use to modify the javascript that gets output to the page.
