拉風的jQuery制作的手風琴折疊菜單，效果非常不錯!這里是之前版本的改進版，主要是jquery代碼改進
演示圖：
main.js
$(function(){ var tmp = null, $title = $('.title'), $con = $('.title > ul'); $title.click(function(){ $(tmp).children('ul').slideUp().end().children('.arrow').removeClass('arrow-up'); $(this).children('ul').slideToggle().end().children('.arrow').addClass('arrow-up'); tmp = this; }); $con.click(function(){ return false; // 阻止事件冒泡 });});index.html
