WordPress插件按需加载js和css

Question

I created plugin with shortcode. I want to load js and css of my plugin only if i use the plugin(the shortcode in my post). I found few examples and i created something like this. Is it correct way? Everything works but i can't see these scripts in page source (i checked Firefox and chrome)

   public function __construct(){       
        add_shortcode( $this->tag, array($this, 'run_yoolek' ) );
        add_action( 'wp_enqueue_scripts',  array( $this, 'register_my_script' ) );  
    }

    public function run_yoolek(){

        wp_enqueue_style('yoolek-googlemap-simple-css');
        wp_enqueue_script('google-maps');
        wp_enqueue_script( 'yoolek-googlemap-simple-js' );

        ob_start();
        ...
        return ob_get_clean();
    } 

    public function register_my_script() {
        wp_register_style( 'yoolek-googlemap-simple-css',plugins_url( '/style.css' , __FILE__ ) );
        wp_register_script( 'google-maps', 'https://maps.googleapis.com/maps/api/js?key=AIzaSyAM10sMY' );
        wp_register_script( 'yoolek-googlemap-simple-js', plugins_url( '/script.js' , __FILE__ ) );

    }   

Answer 1

wp_enqueue_style（）和wp_enqueue_script（）在该位置不起作用，您应该在另一个函数中使用它们，例如，my_scripts_method（）用于wp_enqueue_scripts挂钩。

  add_action( 'wp_enqueue_scripts', array($this, 'my_scripts_method') );
