Answer 1

我在jsFiddle上为你做了几个演示，它是基于Windows的开始菜单，这里是Fiddle

<强> HTML

<footer id="taskbar" class="taskbar">

  <div id="startbutton">
    <img src="start.png" alt="Start"/>
  </div>

</footer>

<强> CSS

#startmenu {
  background: #666;
  position: absolute;
  display: none;
  bottom: 25px;
  left: 0;
  color: gray;
  width: 400px;
  height: 650px;
}
#taskbar {
  background: #444;
  position: absolute;
  bottom: 0;
  left: 0;
  width: 100%;
}
#startbutton {
  background: #ccc;
  width: 50px;
  height: 25px;
  cursor: pointer;
}

<强>的jQuery

// DEMO 1

$(function() {

  $('#startbutton').click(function() {
    $('#startmenu').fadeIn('slow');
  });

  $('#startmenu').mouseleave(function() {
    $(this).fadeOut('slow');
  });

});

// DEMO 2

$(function() {

  $('#startmenu').css({ height: '0', display: 'block' });

  $('#startbutton').click(function() {
    $('#startmenu').stop().animate({ height: '650px' }, 600 );
  });

  $('#startmenu').mouseleave(function() {
    $(this).stop().animate({ height: '0' }, 600 );
  });

});

Answer 2

1 .- 首先，您必须拥有unique个ID。您#startbutton和div元素都有img。

2 .- 您需要在要显示/隐藏的div中显示可见内容，或者使用CSS添加一些高度/宽度/边框等，这样您才能真正看到它。否则它就在那里，但你不会看到它。

<div id="startmenu" class="startmenu">CONTENT</div>，通过添加文字可以看到它; 和/或使用CSS为其指定高度/宽度/背景颜色/边框。

试试这个

将此添加到您的css display:none;，以便在页面加载时隐藏div，然后您可以尝试使用代码，它可以正常运行
