在iOS上，您可以拖动以从顶部显示一个菜单来查看通知。您也可以在Android上执行相同的操作。

我正在一名Web设计人员中工作，我将使用这种类型的效果，并且我一直试图在jQuery中进行此操作，但很难使其仅更改元素的大小（即.reveal）。

$('strong').click(function() {
  $('.reveal').animate({ 'height': 'toggle' }, 100)
});

// Handles FunctionBar
$(".functionbar").draggable({
  axis: "y",
  handle: ".handlesbar",
  disabled: false
});

$(".revealbar").draggable({
  axis: "y",
  //containment: "parent",
  helper: "clone",
  drag: function (event, ui) { 
    var height = ui.offset.top; 
    $(this).prev().height(height); 
    $(".revealbar.ui-draggable-dragging").addClass("hide").css({
      "height": "0",
      "overflow": "hidden"
    });
  }
});

body {
  background:  #aaa;
}

/* FunctionBar */
.functionbar {
  overflow: hidden;
}

.handlesbar {
  margin: auto;
  width: 90%;
  padding: 6px 0;
  border-radius: 10px 10px 0 0;
  font: 24px arial;
  text-align: center;
  background: hsla(180, 0%, 0%, .75);
  word-spacing: 12px;
}

a {
  text-decoration: none;
  color: hsl(180, 0%, 90%);
}

.active {
  color: #9cf;
}

.hide {
  display: none;
}

/* Drag to Reveal Elements */
.reveal {
  margin: auto;
  width: 90%;
  background: #fff;
  overflow: visible!important;
  display:none;
}
.reveal, .revealcontent {
  z-index: 0;
  overflow: auto;
}
.revealbar {
  cursor: default;
  text-align: center;
  background: #666;
  color: #1c1c1c;
  z-index: 1;
  overflow: hidden;
}
.reveal h1 {
  margin: 0;
  padding: 16px 0;
}

删除“包含”参数：

$(".revealbar").draggable({
axis: "y",
//containment: "parent",
helper: "clone",
drag: function (event, ui) { 
    var height = ui.offset.top; 
    $(this).prev().height(height); 
    $(".revealbar.ui-draggable-dragging").addClass("hide").css({
        "height": "0",
        "overflow": "hidden"
    });
}
});
