Parametri

Scoraggiando gli script in functions.php

Se vuoi aggiungere lo script custom.js che si trova nella cartella js/ del tuo tema, dovrai accodarlo. In functions.php aggiungi

<?php

add_action( 'after_setup_theme', 'yourtheme_theme_setup' );

if ( ! function_exists( 'yourtheme_theme_setup' ) ) {
    function yourtheme_theme_setup() {

        add_action( 'wp_enqueue_scripts', 'yourtheme_scripts' );
        add_action( 'admin_enqueue_scripts', 'yourtheme_admin_scripts' );

    }
}

if ( ! function_exists( 'yourtheme_scripts' ) ) {
    function yourtheme_scripts() {

        wp_enqueue_script( 'yourtheme_custom', get_template_directory_uri().'/js/custom.js', array( 'jquery' ), '1.0.0', true );

    }
}

if ( ! function_exists( 'yourtheme_admin_scripts' ) ) {
    function yourtheme_admin_scripts() {

        wp_enqueue_script( 'yourtheme_custom', get_template_directory_uri().'/js/custom.js', array( 'jquery-ui-autocomplete', 'jquery' ), '1.0.0', true );

    }
}

Script Enqueue solo per IE

add_action( 'wp_enqueue_scripts', 'enqueue_my_styles_and_scripts' );

/**
 * Enqueue scripts (or styles) conditionally.
 *
 * Load scripts (or stylesheets) specifically for IE. IE10 and above does
 * not support conditional comments in standards mode.

 */
function enqueue_my_styles_and_scripts() {

     // Internet Explorer HTML5 support
    wp_enqueue_script( 'html5shiv',get_template_directory_uri().'/js/html5shiv.js', array(), '3.7.3', false);
    wp_script_add_data( 'html5shiv', 'conditional', 'lt IE 9' );

    // Internet Explorer 8 media query support
    wp_enqueue_script( 'respond', get_template_directory_uri().'/js/respond.js', array(), '1.4.2', false);
    wp_script_add_data( 'respond', 'conditional', 'lt IE 9' );

}

Scoraggiando script in modo condizionale per pagine specifiche

Puoi utilizzare operatori condizionali in WordPress per accodare script su pagine specifiche del tuo sito web.

function load_script_for_single_post(){
    if(is_single()){
        wp_enqueue_script(
                'some',
                get_template_directory_uri().'/js/some.js',
                array('jquery),
                '1.0.0', 
                false
        );

    }
} 
add_action('wp_enqueue_scripts','load_script_for_single_post');

Nell'esempio precedente, se la pagina web corrente è single post, lo script verrà accodato. Altrimenti la funzione wp_enqueue_script non verrà eseguita.
