Message box when accessed from iPad

Question

I am still looking for a solution for this and can't seem to find it. I have the following code to start, but am not sure how to write the function to fire off a .js file. I need this to work on one specific page ID.

function ipad_alert() {
 if( preg_match('/ipad/i',$_SERVER['HTTP_USER_AGENT'])) {?>
      // link to .js file? 
 <?php }
 }
 add_action('init','ipad_alert');

Answer 1

use wp_enqueue_script() to add a js file. I've hooked wp_enqueue_scripts so I can check is_page() for a specific page.

function ipad_alert() {
    if( preg_match('/ipad/i',$_SERVER['HTTP_USER_AGENT']) && is_page(7) ) {
        wp_enqueue_script('my_script', get_bloginfo('template_directory') . '/js/my_script.js');
    }
}
add_action('wp_enqueue_scripts','ipad_alert');
