Cookie是最简单的方法.
每次进行搜索时，检索现有的cookie，如果已经有五个，则删除最旧的cookie，然后将新的serach添加到cookie列表中.然后将其保存回去.

您需要做的是保留最近5次搜索.

要保留数据，您可以使用
1. Cookie(客户端)
2.会话(服务器端)
3.存储到数据库

在上述3个选项中，如果搜索字符串的长度不是很大，我宁愿将数据存储在cookie中.

您可以使用分隔符创建一个字符串，就像这样
搜索1;搜索2;搜索3 .....
并将字符串存储在cookie中.

在获取字符串的同时，阅读cookie并将其显示在您希望显示的任何位置.

希望这会有所帮助.

What you need to do is to persist the last 5 searches.

To persist data you can use
1. cookie (client side)
2. session (server side)
3. storing to database

Among the above 3 options, I would prefer storing data in cookie provided the search string length is not so big.

You can create a string with a delimiter, some thing like this
search 1;search 2;search 3.....
and store the string in cookie.

While getting the string, read the cookie and show it wherever you want it to show.

Hope this helps.
cheers
