多个JQuery手风琴菜单-使用cookie记住唯一状态（持久状态）
我是jquery新手，这里需要一些帮助。我正在使用一个基于CSS、JavaScript和jQuery的手风琴菜单。。。我有一个问题，我希望这里的一些大师能回答。。。我的经验来自ASP和ActionScript，所以我需要一些指导或帮助 我没有问题设置和调整菜单，并将其设置为保存其打开状态，但我正在工作的网站是相当大的，菜单完全改变从一个网站部分到另一个。问题是保存的打开状态从一个菜单传递到网站其他部分的所有其他菜单。示例：如果菜单1中保存的打开状态为标题2，则用户使用菜单2导航到网站的另一部分，菜单将打开菜单1的保存状态，该状态为标题2，这变得非常奇怪。我知道这是通过一个在会话结束时过期的cookie完成的，为该cookie传递的值是类似c0、c1、c2之类的东西。c0表示收割台1，c1表示收割台2，依此类推。我还知道，我可以在每次菜单请求中传递查询字符串，以打开某个标题项，例如多个JQuery手风琴菜单-使用cookie记住唯一状态（持久状态）,jquery,cookies,accordion,state,Jquery,Cookies,Accordion,State,我是jquery新手，这里需要一些帮助。我正在使用一个基于CSS、JavaScript和jQuery的手风琴菜单。。。我有一个问题，我希望这里的一些大师能回答。。。我的经验来自ASP和ActionScript，所以我需要一些指导或帮助 我没有问题设置和调整菜单，并将其设置为保存其打开状态，但我正在工作的网站是相当大的，菜单完全改变从一个网站部分到另一个。问题是保存的打开状态从一个菜单传递到网站其他部分的所有其他菜单。示例：如果菜单1中保存的打开状态为标题2，则用户使用菜单2导航到网站的另一部分，
