在阅读一些小说或图片类网站时,为了方便大家阅读,往往会加入利用键盘方向键进行翻页、返回上一级、返回目录、回首页等功能。一个小小的人性化功能,却给用户很大的方便。下面介绍一下这个小程序的用法。
功能描述:
按下向左方向键转到:www.baidu.com
按下向右方向键转到:haoji.la网址大全
按下回车键转到:www.faydo.com
按下CTRL+回车键转到:www.faydo.com
实现本功能的javascript代码:
<script language=javascript>
document.onkeydown=nextpage
var prevpage="http://www.baidu.com/" //左方向键去百度
var nextpage="http://haoji.la/" //右方向键去好极啦
var bookpage="http://www.faydo.com/" //回车键去飞度网
function nextpage(event)
{
event = event ? event : (window.event ? window.event : null);
if (event.keyCode==13) location=bookpage;//回车键
if (event.keyCode==37) location=prevpage;//左方向键
if (event.keyCode==39) location=nextpage;//右方向键
if (event.ctrlKey && event.keyCode==13) {alert("你点了 ctrl + enter ,现在转向到 飞度网."); location="http://www.faydo.com/";} //同时按下键盘多个键的事件情况
}
</script>
