Drupal programmatically remove JavaScript

I am trying to disable the JavaScript when the user is using IE. Is there a way to accomplish this in template.php or a custom module?

As alternative to handling the content of $vars['scripts'], which is a string containing the HTML to output in the <head> tag, you could use the value returned from drupal_add_js(NULL, NULL, 'header'), which is similar to the following one:

$header_javascript = array(
  'core' => array(
    'misc/jquery.js' => array(
      'cache' => TRUE,
      'defer' => FALSE,
      'preprocess' => TRUE,
    ), 
    'misc/drupal.js' => array(
      'cache' => TRUE,
      'defer' => FALSE,
      'preprocess' => TRUE,
    ),
  ), 
  'module' => array(), 
  'theme' => array(), 
  'setting' => array(
    array('basePath' => base_path()),
  ), 
  'inline' => array(),
);

The "module" index contains the reference to the JavaScript files added from the modules, "settings" contains all the JavaScript settings generally added by the modules, and "inline" contains inline JavaScript code.
It could help if you need to distinguish between the different JavaScript files, and (for example) not touch any JavaScript file that has been marked as "core."

The counterbalance is that to populate the content of $vars['scripts'] you need to duplicate part of the code used from drupal_get_js(). As you would need a customized code, you would not duplicate all the code of that function, but you still would duplicate part of it.

In Drupal 7, the variable $vars['scripts'] is not passed anymore to template_preprocess_page() (and similar preprocess functions implemented by modules or themes); it is passed to template_preprocess_html().

You can use the preprocess_page() hook in template.php.

function YOUR_THEME_preprocess_page(&$vars) {
  if (isset($_SERVER['HTTP_USER_AGENT']) && (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false)) {
    $vars['scripts'] = 'get a mac!';
  }
}

Obviously you should do something more intelligent with the $vars['scripts'] content :)
