WP_Widget_Text::enqueue_preview_scripts() public WP 4.9.3

Enqueue preview scripts.

These scripts normally are enqueued just-in-time when a playlist shortcode is used. However, in the customizer, a playlist shortcode may be used in a text widget and dynamically added via selective refresh, so it is important to unconditionally enqueue them.

{} It's a method of the class: WP_Widget_Text{}

No Hooks.

Return

null. Nothing.

Usage

$WP_Widget_Text = new WP_Widget_Text();
$WP_Widget_Text->enqueue_preview_scripts();
