Remove type attribute from script and style tags added by WordPress plugins

Question

I am using the function below to remove type attribute from a script and style tags but this function doesn't remove the type attribute from the scripts/styles added by the plugins. It only works on my theme files.

add_filter('style_loader_tag', 'codeless_remove_type_attr', 10, 2);
add_filter('script_loader_tag', 'codeless_remove_type_attr', 10, 2);

function codeless_remove_type_attr($tag, $handle) {
    return preg_replace( "/type=['\"]text\/(javascript|css)['\"]/", '', $tag );
}

Answer 1

The following code worked for me, please try this by pasting the code into you function.php file.

add_action('wp_loaded', 'prefix_output_buffer_start');
function prefix_output_buffer_start() { 
    ob_start("prefix_output_callback"); 
}

add_action('shutdown', 'prefix_output_buffer_end');
function prefix_output_buffer_end() { 
    ob_end_flush(); 
}

function prefix_output_callback($buffer) {
    return preg_replace( "%[ ]type=[\'\"]text\/(javascript|css)[\'\"]%", '', $buffer );
}

Hope this will work for you too.
