当方框状态更改时，使用javascript提交表单。然后，可以使用wp\\u query创建新查询，并使用tax\\u query显示选中的分类：

$args = array(
    ... // posttype and such
    \'tax_query\' => array(),
    ...// other arguments 
);
//if post is set
if(isset($_POST[\'cats\'])){
    //pusch to array
    $args[\'tax_query\'][] = array(
        \'taxonomy\' => \'the taxonomy\',
        \'field\' => \'id\', // get tax by id or slug
        \'terms\' => $_POST[\'cats\'],
        \'operator\' => \'AND\' // or you can choose \'IN\'
    );
}
$new_query = new Wp_Query($args);
//start loop
while ($new_query->have_posts() ) : $new_query->the_post(); ?>
