parameter is used.源码

Run the filter only once per page load. if ( ! isset( $omit_threshold ) || $force ) { /** * Filters the threshold for how many of the first content media elements to not lazy-load. * * For these first content media elements, the `loading` attribute will be omitted. By default, this is the case * for only the very first content media element. * * @since 5.9.0 * @since 6.3.0 The default threshold was changed from 1 to 3. * * @param int $omit_threshold The number of media elements where the `loading` attribute will not be added. Default 3. */ $omit_threshold = apply_filters( 'wp_omit_loading_attr_threshold', 3 ); } return $omit_threshold; }
