为什么 jQuery 移动设备上的弹出式滚动不起作用？

Question

我正在使用 jquery.mobile-1.4.5。我的情况是滚动在我的应用程序上不起作用。

此代码是我的 index.html 我的数据是从我的网络服务上的 JSON 获取的。

<div role="main" class="ui-content">
  <div data-role="popup" id="popupBasic" data-transition="slideup" style="height: 500px;">
    <div data-role="header" style="background: none;">
      <h1 class="poppinmedium" style="font-size:14px;">Detail Information</h1>
    </div>
    <div class="content">
      <div class=" img-responsive" id="img-container" style="text-align: center;"></div>
      <h4 id="poi-detail-title" class="poppinmedium" style="text-align: center;"></h4>
      <!-- <h4 style="text-align: center;" class="poppinthin">Distance:
          <span id="poi-detail-distance" class="poppinthin"></span>
      </h4> -->
      <h4 id="poi-detail-description" class="poppinthin"></h4>
    </div>
  </div>
</div>

这里是我弹出窗口的 CSS 代码。

.ui-popup-container {
  z-index: 1000;
  display: inline-block;
  position: absolute;
  /* background: #fff; */
  padding: 0;
  outline: 0;
  /* overflow: auto; */
  max-width: 100% !important;
  top: auto !important;
  bottom: 0 !important;
  left: 0 !important;
  width: 100%;
}

.ui-popup {
  border-radius: 20px 20px 0px 0px;
  padding-bottom: 8px;
  padding-left: 8px;
  padding-right: 8px;
  padding-top: 10px;
}

这是打开弹出窗口并滚动它的代码。但它不起作用：

$('#popupBasic').popup('open');
$('#popupBasic').on({
  popupafteropen: function() {
    var maxHeight = 400;
    $('#popupBasic').css('max-height', maxHeight + 'px');
    $('#popupBasic').css('overflow', 'auto');
  }
});

Answer 1

为什么你需要 z-index？ JQM 已经在设置自己的 z-index。例如，弹出屏幕覆盖（捕获弹出窗口外的点击）有 z-index 1099，弹出容器（用于边框和默认关闭按钮）有 z-index 1100。

如果您需要带有自动滚动内容的弹出窗口，请设置弹出内容的 overflow。

演示：

$(function(){
  var longText = ['<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi. Nulla quis sem at nibh elementum imperdiet. Duis sagittis ipsum. Praesent mauris. Fusce nec tellus sed augue semper porta. Mauris massa. Vestibulum lacinia arcu eget nulla. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>',
    '<p>Curabitur sodales ligula in libero. Sed dignissim lacinia nunc. Curabitur tortor. Pellentesque nibh. Aenean quam. In scelerisque sem at dolor. Maecenas mattis. Sed convallis tristique sem. Proin ut ligula vel nunc egestas porttitor. Morbi lectus risus, iaculis vel, suscipit quis, luctus non, massa. Fusce ac turpis quis ligula lacinia aliquet. Mauris ipsum. </p>',
    '<p>Nulla metus metus, ullamcorper vel, tincidunt sed, euismod in, nibh. Quisque volutpat condimentum velit. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Nam nec ante. Sed lacinia, urna non tincidunt mattis, tortor neque adipiscing diam, a cursus ipsum ante quis turpis. Nulla facilisi. Ut fringilla. Suspendisse potenti. Nunc feugiat mi a tellus consequat imperdiet. Vestibulum sapien. Proin quam. Etiam ultrices. Suspendisse in justo eu magna luctus suscipit. </p>'
    ].join('');

  $('#popupBasic').on({
    popupafteropen: function() {
      var maxHeight = 400;
      $('#popupBasic .ui-content').css({
        'max-height': maxHeight + 'px',
        'overflow': 'auto'});
      setTimeout(function(){ 
        $("#popupBasic .ui-content").html(longText);
      }, 1000);
    },
    popupafterclose: function() {
      $("#popupBasic .ui-content").html("");
    }
  });
});

/* 12 px is the JQM default blur for box-shadows */
.ui-popup-container {
  max-width: 100% !important;
  top: auto !important;
  bottom: 12px !important;
  left: 12px !important;
  right: 12px !important;
}
