Views is loading these files, I need to dequeue them but I can't:

mediaelement/mediaelement-and-player.min.js?ver=2.22.0
js/mediaelement/wp-mediaelement.min.js?ver=4.7.4
js/mediaelement/wp-playlist.min.js?ver=4.7.4
plugins/wp-views/embedded/res/js/wpv-pagination-embedded.js?ver=2.3.1
js/wp-embed.min.js?ver=4.7.4
js/jquery/ui/datepicker.min.js?ver=1.11.4

and here are some snippets of code, that are loaded which I don't use/need:

<script type="text/html" id="tmpl-wp-playlist-current-item">
	<# if ( data.image ) { #>
	<img src="{{ data.thumb.src }}" alt="" />
	<# } #>
	<div class="wp-playlist-caption">
		<span class="wp-playlist-item-meta wp-playlist-item-title">&#8220;{{ data.title }}&#8221;</span>
		<# if ( data.meta.album ) { #><span class="wp-playlist-item-meta wp-playlist-item-album">{{ data.meta.album }}</span><# } #>
		<# if ( data.meta.artist ) { #><span class="wp-playlist-item-meta wp-playlist-item-artist">{{ data.meta.artist }}</span><# } #>
	</div>
</script>
<script type="text/html" id="tmpl-wp-playlist-item">
	<div class="wp-playlist-item">
		<a class="wp-playlist-caption" href="{{ data.src }}">
			{{ data.index ? ( data.index + '. ' ) : '' }}
			<# if ( data.caption ) { #>
				{{ data.caption }}
			<# } else { #>
				<span class="wp-playlist-item-title">&#8220;{{{ data.title }}}&#8221;</span>
				<# if ( data.artists && data.meta.artist ) { #>
				<span class="wp-playlist-item-artist"> &mdash; {{ data.meta.artist }}</span>
				<# } #>
			<# } #>
		</a>
		<# if ( data.meta.length_formatted ) { #>
		<div class="wp-playlist-item-length">{{ data.meta.length_formatted }}</div>
		<# } #>
	</div>
</script>

Here's the php in my functions.php but it does nothing:

add_action('wp_enqueue_scripts', 'cleanup_scripts', 11);
function cleanup_scripts() {
if (!is_admin()) {
global $WP_Views;
wp_dequeue_style( 'views-pagination-style' );

wp_dequeue_script( 'wpv-front-end-utils' );
wp_dequeue_style( 'views-table-sorting-style' );
wp_dequeue_style( 'wpv_render_css' );
wp_dequeue_script( 'jquery-ui-core' );
wp_dequeue_script( 'jquery-ui-datepicker' );
wp_dequeue_script( 'jquery-ui-datepicker-local' );
wp_dequeue_script( 'wpv-date-front-end-script' );
remove_action('wp_print_styles', array($WP_Views, 'add_render_css'));
remove_action('wp_head', 'wpv_add_front_end_js');
}
}

Please help me rid of these bloats!

Thanks

Hi Andy

Toolset has its own system for enqueuing styles and scripts, but it is still based upon the standard WordPress registering and enqueuing functions, and you should be able to dequeue the unwanted scripts or styles before they are added to the page.

The recommended hooks to use are wp_print_scripts and wp_print_styles respectively, which run immediately prior to the scripts and style links being printed to the page. Used with a late priority it will ensure you are attempting to dequeue them once they have been enqueued.

Here is a simple example I used to dequeue the pagination script and stylesheet from the front-end:

function cleanup_scripts() {

	if ( !is_admin() ) {

		wp_dequeue_script( 'views-pagination-script' );

	}
}
add_action( 'wp_print_scripts', 'cleanup_scripts', 100 );

function cleanup_styles() {

	if ( !is_admin() ) {

		wp_dequeue_style( 'views-pagination-style' );

	}
}
add_action( 'wp_print_styles', 'cleanup_styles', 100 );

I don't recognise the code snippets for the media player controls, do you know what is adding them?

The datepicker script is a dependancy of the pagination script, so removing that should remove datepicker, too, unless something else is trying to add it.

This is added with views, when I deactivate views it isn't added.

Hi Andy

It looks like the media element files are dependencies for the Views navigation script which my sample code dequeues, so I'm not sure why they are still being loaded.

By dequeuing views-pagination-script it removes those dependencies at the same time. On my local test site that's what I experience, removing views-pagination-script also dequeues the media element and playlist scripts.

Can I just check, are you still seeing those scripts added after adding the code to dequeue views-pagination-script?

[AndyS4926]

yes it removes it, however I am in a catch 22.

I will need the pagination script so will it be possible to remove the datepicker without removing the pagination?

Hi Andy

Sorry for the delay getting back to you.

Well, the datepicker script is declared as a dependency of the pagination script, so if you leave the pagination script enqueued WordPress will automatically and unavoidably load the datepicker script, too.

The only solution I can think of is to dequeue the pagination script and the re-enqueue it yourself, without specifying datepicker as a dependency (you'll probably want to specify at least jQuery as a dependency).

I haven't tried it and can't be sure it would work but given how the pagination script is currently enqueued by Views there is no other means I can think of.

If you do try let me know how you get on as I would be curious to know.
