 piano = function () {
 _menu ='[{"title":"一级目录","img":"images/cog.png","submenu":[{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"}]},{"title":"一级目录","img":"images/cog.png","submenu":[{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"},{"id":"4","title":"二级目录","img":"images/monitor_window_3d.png"}]}]';
 return ep = {
 init: function (obj) {
 _menu = eval('(' + _menu + ')');
 var li ="";
 $.each(_menu, function (index, element) {
 li += '<li><p class="titlemenu"><img src=' + element.img + ' width="16" height="16" alt=""/><span>' + element.title + '</span></p>';
 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);
