css樣式

/* CSS Document */
body {
  margin: 0 auto;
  padding: 0 auto;
  font-size: 9pt;
  font-family: 微軟雅黑, 宋體, Arial, Helvetica, Verdana, sans-serif;
}
.accordion {

.submenu li span {
  display: inline-block;
  height: 30px;
  padding: 5px 0px;
}
.hover {
  background-color: #4A5B79;
}

自定義js

(function ($) {
  piano = function () {
    _menu ='[{"title":"一級目錄","img":"images/cog.png","submenu":[{"title":"二級目錄","img":"images/monitor_window_3d.png"},{"title":"二級目錄","img":"images/monitor_window_3d.png"},{"title":"二級目錄","img":"images/monitor_window_3d.png"}]},{"title":"一級目錄","img":"images/cog.png","submenu":[{"title":"二級目錄","img":"images/monitor_window_3d.png"},{"title":"二級目錄","img":"images/monitor_window_3d.png"},{"id":"4","title":"二級目錄","img":"images/monitor_window_3d.png"}]}]';
    return ep = {
      init: function (obj) {
        _menu = eval('(' + _menu + ')');
         var li ="";
        $.each(_menu, function (index, element) {
          li += '<li><div class="titlemenu"><img src=' + element.img + ' width="16" height="16" alt=""/><span>' + element.title + '</span></div>';
          if(element.submenu!=null)
          {
            li+='<ul class="submenu">';
            $.each(element.submenu, function (ind, ele) {
              li += '<li><img src=' + ele.img + ' width="16" height="16" alt=""/><span><a href="#">' + ele.title + '</a></span></li>';
            });
            li+='</ul>';
          }
          li+='</li>';
        });
        obj.append(li);
      }
    }
  }

  $.fn.accordion = function (options) {
    var pia = new piano();
    pia.init($(this));
    return this.each(function () {
      var accs = $(this).children('li');
       accs.each(reset);
      accs.click(onClick);
      var menu_li = $(".submenu").children("li");
      menu_li.each(function (index, element) {
        $(this).mousemove(function (e) {
          $(this).siblings().removeClass("hover");
          $(this).find("a").css("color", "#fff");
          $(this).siblings().find("a").css("color", "#000");
          $(this).addClass("hover");
        });
      });
    });
  }

  function onClick() {
    $(this).siblings('li').find("ul").each(hide);
    $(this).find("ul").slideDown('normal');
    return false;
  }

  function hide() {
    $(this).slideUp('normal');
  }

  function reset() {
    $(this).find("ul").hide();
  }
})(jQuery);

html調(diào)用方式

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>無標(biāo)題文檔</title>
<script src="jquery-1.8.0.min.js"></script>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="accordion.js"></script>
<script type="text/javascript">      
  $(function(){
    $("#accordion").accordion();
  });
</script>
</head>
<body>
<ul id="accordion" class="accordion" style="width:200px;height:500px;">
</ul>
</body>
</html>
