我在 Adob​​e Business Catalyst 站点上创建的页面中实现一些简单的 jQuery 时遇到了一些麻烦。我在下面包含了相关的 HTML：

<div class="banner-main">
  <div class="banner-top">
    <section class="banner">
      <div class="catProdAttributeItem">
        <select id="banner-pic">
          <option value="30644690">Red </option>
          <option value="30791632">Purple </option>
        </select>
      </div>
    </section>
  </div>
</div>

以下 HTML 是创建页面时生成的内容：

<div class="banner-main">
  <div class="banner-top">
    <section class="banner">
      <div class="catProdAttributeItem">
        <div class="ddOutOfVision" id="banner-pic_msddHolder" style="height: 0px; overflow: hidden; position: absolute;">
          <select id="banner-pic" tabindex="-1">
            <option value="30644690">Red </option>
            <option value="30791632">Purple </option>
          </select>
        </div>
        <div class="dd ddcommon borderRadius" id="banner-pic_msdd" tabindex="0" style="width: 422px;">
          <div class="ddTitle borderRadiusTp">
            <span class="divider"></span>
            <span class="ddArrow arrowoff"></span>
            <span class="ddTitleText " id="banner-pic_title">
              <span class="ddlabel">Purple</span>
              <span class="description" style="display: none;"></span>
            </span>
          </div>
          <input id="banner-pic_titleText" type="text" autocomplete="off" class="text shadow borderRadius" style="display: none;">
          <div class="ddChild ddchild_ border shadow" id="banner-pic_child" style="z-index: 1; position: absolute; visibility: visible; height: 59px; top: 40px; display: none;">
            <ul>
              <li class="enabled _msddli_ selected">
                <span class="ddlabel">Red</span>
                <div class="clear"></div>
              </li>
              <li class="enabled _msddli_">
                <span class="ddlabel">Purple</span>
                <div class="clear"></div>
              </li>
            </ul>
          </div>
        </div>
      </div>
    </section>
  </div>
</div>

如您所见，msDropDown正在更改选择下拉菜单并将其变成无序列表。.banner-main div 有一个背景图片，我想根据下拉选择更改该图片。下面的 jQuery 是我第一次，最直接的尝试，但没有奏效：

<script type="text/javascript">

  var pictureList = [
    'url(images/red.jpg)',
    'url(images/purple.jpg)', ];

  $(document).ready(function(){
    $('li.enabled._msddli_').click(function() {
      alert('clicked');
      var val = $('li.enabled._msddli_.selected').index();
      $('.banner-main').css('background-image', pictureList[val]);
    });
  });
</script>

从那以后，我又尝试了几件事，但无论出于何种原因，msDropDown 生成的任何元素都没有触发 .click() 事件。我很困惑，所以任何帮助将不胜感激！

$('#banner-pic_child').on('click', '.li.enabled._msddli_', function (event) {
      alert('clicked');
      var val = $('li.enabled._msddli_.selected').index();
      $('.banner-main').css('background-image', pictureList[val]);
    });

解决您的问题？
