Add JS to the bottom of the page in Drupal 7

How to add JS at bottom of a particular page in Drupal 7 Step 1: Get the page id. In case of front page "is_front"  Step 2: In template.php file of your theme add the below code : function illume_preprocess_page(&$variables) { if ($variables['is_front']) { drupal_add_js(path_to_theme().'/js/util.js', array('type' => 'file', 'scope' => 'footer')); drupal_add_js(path_to_theme().'/js/main.js', array('type' => 'file', 'scope' => 'footer')); drupal_add_js(path_to_theme().'/js/slideimage.js', array('type' => 'file', 'scope' => 'footer')); $variables['bottom_scripts'] = drupal_get_js(); } } This way you can add JS file using drupal_add_js() and define scope as footer.
