[gyl086]

我去下载过了,可是我觉得解决的不是我要的问题

[若白师妹]

ajax去做

[gyl086]

楼上大哥你好,我没用过你说的这个,能不能给点代码啊,非常感谢!

[斯洛文尼亚旅游]

ajax或者隐藏的iframe

ajax例子可以去这里下自己看看

就是ajax提交数据返回后台处理再赋给隐藏DIV

[gyl086]

楼上的你好啊,ajax俺没有学过,也没有用过,能不能给点代码啊?比如:数据库aa,表a1(user_name,user_sex),ip本地.
用asp来实现.谢谢!

[一天到晚游泳的鱼2016]

其实就是模仿google suggest 下拉菜单
http://blog.csdn.net/sandyxxx/archive/2008/02/03/2079690.aspx
这里有源代码，你看看吧。

[gyl086]

chinmo 你好,不好意思,您说的红色部分怎么该成数据库里的数据呢?比如:数据库aa,表a1(user_name,user_sex),ip本地.
