挣扎着循环并打开弹出窗口

Question

我对jQuery不是很有经验，我想在它所在的div上打开这个弹出窗口（所以有些东西用$（这个）我假设，只是不能让它工作:(），当我点击<a class="btn" data-popup-open="popup-1" href="#">Bekijk trekker</a>。现在发生的事情是它会打开循环中每个项目的每个弹出窗口。这是我的jQuery和HTML。

<div class="container">

    <h1> Trekkers </h1>

    <section id="filter">
        Filter
    </section>

    <section id="tractoren">

        <?php
            $args = array( 
                'post_type' => 'tractoren', 
                'posts_per_page' => -1 
            );
            $loop = new WP_Query( $args );
            while ( $loop->have_posts() ) : $loop->the_post();
        ?>

            <div class="tractor">

                <figure>
                    <?php the_post_thumbnail('tr_thumb'); ?>
                </figure>

                <div id="content">

                    <h3> <?php the_title(); ?> </h3>
                    <span> Bouwjaar: <?php the_field('tractoren_bouwjaar'); ?> </span>
                    <span> Uren: <?php the_field('tractoren_uren'); ?> </span>

        <a class="btn" data-popup-open="popup-1" href="#">Bekijk trekker</a>

        <div class="popup" data-popup="popup-1">
            <div class="popup-inner">
                <h2><?php the_title(); ?></h2>
                <p><a data-popup-close="popup-1" href="#">Close</a></p>
                <a class="popup-close" data-popup-close="popup-1" href="#">x</a>
            </div>
        </div>

        <script>

          $(function() {

              $('[data-popup-open]').on('click', function(e)  {
                  var targeted_popup_class = jQuery(this).attr('data-popup-open');
                  $('[data-popup="' + targeted_popup_class + '"]').fadeIn(350);
                  e.preventDefault();
              });

              $('[data-popup-close]').on('click', function(e)  {
                  var targeted_popup_class = jQuery(this).attr('data-popup-close');
                  $('[data-popup="' + targeted_popup_class + '"]').fadeOut(350);
                  e.preventDefault();
              });
          });
        </script>

                </div>

                <span class="price">
                    <?php if( get_field('tractoren_prijs') ): ?>
                        <?php the_field('tractoren_prijs'); ?>
                    <?php endif; ?>

                    <?php if( !get_field('tractoren_prijs') ): ?>
                        <?php echo 'Prijs onbekend' ?>
                    <?php endif; ?>

                </span>

            </div>

        <?php endwhile; ?>

    </section>

</div>

感谢。

我建议您使用已有的类.btn和.popup-close。

您可以使用 next() 方法打开弹出窗口：

$('.btn').on('click', function(e) {
  $(this).next('.popup').fadeIn();
  e.preventDefault();
});

和 parent() 表示关闭：

$('.popup-close').on('click', function(e) {
  $(this).parent().parent().fadeOut();
  e.preventDefault();
});

以下演示片段：

＆＃13;

＆＃13;

$(function() {
  $('.btn').on('click', function(e) {
    $(this).next('.popup').fadeIn();
    e.preventDefault();
  });
  $('.popup-close').on('click', function(e) {
    $(this).parent().parent().fadeOut();
    e.preventDefault();
  });
});

＆＃13;

.popup {
  display: none;
}
