Question

我在后台生成的表单中有一些下拉列表。在下拉列表中的每个选项结束时，在（括号）之间添加一些内容。我怎么能不显示这些括号及其变量内容？只留下括号前的内容。

<?php
    $magazine_category_object=get_queried_object();
    $magazine_category_taxonomy_slug = $magazine_category_object->slug;
    $magazine_category_term_id = $magazine_category_object->term_id;

    $magazine_type = 'magazine';
    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

    $magazine_args=array(
        'type'                     => $magazine_type,
        'post_status'              => 'publish',
        'posts_per_page'           => 4,
        'paged'                    => $paged, 
        'caller_get_posts'         => -1,
        'child_of'                 => 0,
        'parent'                   => 0,
        'order'                    => 'ASC',
        'hide_empty'               => 0,
        'hierarchical'             => 1,
        'exclude'                  => '',
        'include'                  => '',
        'number'                   => '',
        'tax_query'                => array(
                                            array(
                                                'taxonomy' => $magazine_category_taxonomy_slug,
                                                'field' => 'id',
                                                'terms' => $magazine_category_term_id
                                            )
                                        ),
        'pad_counts'               => false 
    );
    $magazine_my_query = null;
    $magazine_my_query = new WP_Query($magazine_args);

    if( $magazine_my_query->have_posts() ) 
    {

        while ($magazine_my_query->have_posts()) : $magazine_my_query->the_post(); 
            $magazine_description = get_the_excerpt($post->ID);

             the_title( '<h1>', '</h1>' );

            if ( has_post_thumbnail() ) {
                    //get_the_post_thumbnail( $post->ID, array( 100, 100) ); 
                    echo  get_the_post_thumbnail($post->ID,"thumbnail"); //thumbnail,medium,large,full,array(100,100)

            }
            echo $magazine_description; 
            echo '<a href="<?php echo get_permalink(); ?>">Read More...</a>';
        endwhile;

    }
    wp_reset_query($magazine_my_query);
 ?>

试试这个;

var carList=[{name:"Audi (45.000)" },{name:"Saab (40.000)"},{name:"Opel (15.000)"},{name:"Audi (45.000)"}];

var $cars=$("#cars");
$cars.empty();
carList.forEach(function(index){
  $cars.append(new Option(index.name.split("(")[0].trim()))
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="cars">
</select>

适用于所有选择元素

$("select").each(function(){
  var $wrapper=$(this);
  var $options=$wrapper.find("option");
  $wrapper.empty();
  $options.each(function(index){
      $wrapper.append(new Option($(this).text().split("(")[0].trim()))
  })
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<select>
<option>Fiat (32.00)</option>
<option>Audi (12.00)</option>
</select>

<select>
<option>Bmw (32.00)</option>
<option>Tofas (22.00)</option>
</select>

<select>
<option>Dog (1.00)</option>
<option>Fish (0.00)</option>
</select>

不显示部分拉下内容？
