效果演示:

①默认页面(index.jsp):

 

②:点击左侧 用户管理 标签下的 用户列表 选项后,右边默认页面内容更新为用户列表页(userList.jsp)的内容 :

 

③:同理,点击 产品管理订单管理 标签下的 产品列表订单列表 时,右侧内容会相应的刷新为产品列表页(productList.jsp)、订单列表页(recordList.jsp)的内容

这样就使用Ajax+div实现了左边菜单选择,右边内容显示的效果,下面就来看看具体的实现过程吧

 

一:

整个演示用的示例程序包含默认页面(index.jsp),用户列表页(userList.jsp),产品列表页(productList.jsp),订单管理页(recordList.jsp)

使用了 Bootstrap 框架和 FontAwesome 的图标(没办法,bootstrap自带的图标太少了o(╯□╰)o),这俩货的使用方法请参见官网,都比较简单

先来看看index.jsp的代码吧,我基本都详细注释了:
