我在做一个页面,需要用到键盘来操作页面
内容我需要从后台库里导出
前台页面我每个页面显示6个物件图片,每个图片下面有一个按钮
怎样才能让键盘焦点在按钮上
还有下面有“上一页,下一页”的按钮,同样怎么才能用键盘来执行页面
各位大大来帮我看看
我看了很多文章,都是静态的页面,动态的页面我找不到相关的内容来学习
谢谢各位大大比如说下面的代码是我显示产品的,最后面有一个按钮,我每个页面显示6个产品,但是我希望可以用键盘来操作按钮的执行和翻页功能,我看了一些文章,都是静态的功能,有没有可以做成动态的? 下面是显示的代码 <table width="150" cellpadding=0 cellspacing=0 >

看不明白.....你意思是使用方向键控制表格中的单元格中连接的选择?设置连接的样式??别发有<%%>的代码,发运行过后生成的html代码
