[wp-hackers] Just a basic "how can this be accomplished?" question.

[Nathaniel Taintor]

First, you will have to know the ID of the particular page you want to
modify. You can create a settings page for users to select that page, or
calculate it however you need to. Store that as a plugin option to save the
trouble of calculating that on every page load.

Hook into wp_enqueue_scripts. That's the best place to set scripts and
styles to enqueue. You can enqueue the scripts using wp_enqueue_script and
wp_enqueue_style, and generate the variables to pass to your javascript
using wp_localize_script.

Your function will look something like this (I'm assuming the page you want
to modify is stored in a function called 'this_plugin_page')

add_action( 'wp_enqueue_script', 'my_plugin_enqueues' );

function my_plugin_enqueues() {
    $plugin_page = get_option( 'this_plugin_page' );
    if ( !is_page( $plugin_page ) )
        return;
    wp_enqueue_script( 'myscript', plugins_url('/js/newscript.js',
__FILE__) );
    $script_vars = array( 'this' => 'that', 'foo' => 'bar' );
    wp_localize_script( 'myscript', 'scriptVars', $script_vars );
    wp_enqueue_style( 'mystyle',  plugins_url('/css/newstyle.css',
__FILE__) );
}
