我正在尝试根据本指南为 WordPress 制作一个语法高亮与 ACF + ACE 编辑器相结合的语法突出显示。我已经这样做了：我正在尝试根据本指南为WordPress制作一个结合ACF + ACE编辑器的语法荧光笔。我已经这样做了： <?php class acf_field_ace_code_editor extends acf_field { // vars var $settings, // will hold info such as dir / path $defaults; // will hold default field options /* * __construct * * Set name / label needed for actions / filters * * @since 3.6 * @date 23/01/13 */ function __construct() { // vars $this->name = 'ace_code_editor'; $this->label = __('Ace Code Editor'); $this->category = __("Basic",'acf'); // Basic, Content, Choice, etc $this->defaults = array( // add default here to merge into your field. // This makes life easy when creating the field options as you don't need to use any if( isset('') ) logic. eg: 'ace_code_editor_type' => 'ace_html', 'ace_code_editor_theme' => 'theme_chrome' ); // do not delete! parent::__construct(); // settings $this->settings = array( 'path' => apply_filters('acf/helpers/get_path', __FILE__), 'dir' => apply_filters('acf/helpers/get_dir', __FILE__), 'version' => '1.0.0' ); } /* * create_options() * * Create extra options for your field.

'css/input.css', array('acf-input'), $this->settings['version'] ); 然后你已经使用了 wp_enqueue_script(array( 'acf-input-ace_code_editor', )); // styles wp_enqueue_style(array( 'acf-input-ace_code_editor', )); 在这种情况下，您应该在注册文件时为 js 和 css 使用不同的处理程序，例如 wp_register_script( 'acf-input-ace_code_editor_js', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version'] ); wp_register_style( 'acf-input-ace_code_editor_css', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version'] ); 然后使用 wp_enqueue_script(array( 'acf-input-ace_code_editor_js', )); // styles wp_enqueue_style(array( 'acf-input-ace_code_editor_css', )); 如果注册时给定的路径正确，希望这能正确地将脚本排入队列，并确保给定路径上有正确的js文件。
