Bootstrap - div 在 div 上滑

Question

我无法理解这个问题：我正在使用 bootstrap 创建一个移动网络应用程序。所以我有一个带有导航栏的容器，一些 divs 和下面的药丸导航：

<div class="container">
<!-- top navbar -->
    <nav class="navbar navbar-default navbar-fixed-top">
    <!-- ... -->
    </nav>

    <div class="tab-content">

        <div role="tabpanel" class="tab-pane active fade in" id="map-panel">
            <div id="map"></div>


            <div class="container-fluid" id="teaser-container">
                <div class="row" id="teaser-slideup-button">
                    <div class="col-xs-12">
                        <a role="button" href="#teaser-content">
                            <i class="fa fa-chevron-up"></i>
                        </a>
                    </div>
                </div>
                <div class="row" id="teaser-header">
                    <div class="col-xs-12">Teaser header</div>
                </div>

                <div id="teaser-content">
                    <div class="row">
                        <div class="col-xs-12">
                            <div style="height: 160px" />
                        </div>
                    </div>
                </div>
            </div>            
        </div>
    </div>

    <nav class="navbar navbar-default navbar-fixed-bottom">
        <!-- ... -->
    </nav>

</div>

我想做的是让#teaser-container 从下方滑过#map。基本上

$('#teaser-slideup-button').on('click', function (e) {

     $('#teaser-container').animate({
            'bottom': '0px'
     });

});

一些相关的CSS：

#teaser-container {
    z-index:1000; 
    position: absolute;
    bottom: -100px;
    background: #fff;
    width: 100%;
    display: inline-block;
    overflow-y: hidden;
}

#map-panel {
    position: absolute;
    top: 0px;
    overflow-y: hidden;
    height: 100%;
    width: 100%;
}

但是，发生的是 div 刚刚出现，似乎动画随后发生，向上滚动地图 div。我在这里创建了一个 JSFiddle：

我想这应该不难，但我在这里有点困惑...如果需要，我很乐意提供更多详细信息。

谢谢！

这可能有帮助也可能没有帮助，看起来和似乎以类似的方式操作，但使用按钮和手风琴。

var map;

function initialize() {
  map = new google.maps.Map(document.getElementById('map-canvas'), {
    zoom: 8,
    center: {
      lat: -34.397,
      lng: 150.644
    }
  });
}

google.maps.event.addDomListener(window, 'load', initialize);

$('.collapse').on('shown.bs.collapse', function() {
  $(this).parent().find(".fa-chevron-up").removeClass("fa-chevron-up").addClass("fa-chevron-down");
}).on('hidden.bs.collapse', function() {
  $(this).parent().find(".fa-chevron-down").removeClass("fa-chevron-down").addClass("fa-chevron-up");
});

html,
body,
#map-canvas {
  height: 100%;
  margin: 0;
  padding: 0;
}
.navbar {
  margin-bottom: 0 !important;
}
.navbar-fixed-bottom .col-md-6 {
  padding: 0;
  border: none;
}
.navbar-fixed-bottom .btn {
  width: 100%;
  height: 50px;
  border-radius: 0;
  margin: 0;
  border: none;
  padding-top: 15px;
}
.navbar-fixed-bottom .panel-group,
.navbar-fixed-bottom .panel-heading {
  padding: 0;
  margin: 0;
  border: none;
  border-radius: 0;
}

Answer 2

我通过重新分组标记解决了这个问题：

<div class="container-fluid" id="teaser-container">

    <div class="teaser-inner">
        <div class="row" id="teaser-slideup-button">
            <div class="col-xs-12">
                <a role="button" href="#">
                    <i class="fa fa-chevron-up"></i>
                </a>
            </div>
        </div>
        <div class="row" id="teaser-header">
            <div class="col-xs-12">Teaser Header</div>
        </div>

        <div class="row" id="teaser-content">
            <div class="col-xs-12">
                <div style="height: 160px" />
            </div>
        </div>
    </div>
</div>

在父级上使用 position:relative，在子级上使用 position:absolute：

#map-panel {
    height: 100%;
    width: 100%;
    position: relative;
}
#teaser-container {
    z-index:1000; 
    position:absolute; 
    bottom: 20px;
    background: #fff;
    width: 100%;
    height:40px;
    overflow: hidden;     
}

并为高度设置动画属性（基本上是 $.slideUp 所做的）

$('#teaser-container').animate({
    'height': '260px'
}, 500);

如果有人知道更优雅的解决方案，请告诉我
