wp_localize_script

Localize a script.

Works only if the script has already been registered.

Accepts an associative array $l10n and creates a JavaScript object:

“$object_name” = {
key: value,
key: value,
…
}

function wp_localize_script( $handle, $object_name, $l10n ) {
	global $wp_scripts;

	if ( ! ( $wp_scripts instanceof WP_Scripts ) ) {
		_wp_scripts_maybe_doing_it_wrong( __FUNCTION__, $handle );
		return false;
	}

	return $wp_scripts->localize( $handle, $object_name, $l10n );
}
