js网页代码怎么写( 二 ) _网页代码

5. 网页上的“上一页,下一页”JS代码怎么写需要准备的材料分别是：电脑、html编辑器、chrome浏览器。
1、首先，打开html编辑器，新建一个html文件，例如：index.html 。
2、在index.html中的<script>；标签，输入js代码：
var now=parseInt(location.href.split('?')[1].split('=')[1]);
$('body').append('<a href="http://www.xuexi88.com/zhishi/index?page='+ (now-1)+'">；上一页</a>');
$('body').append('<a href="http://www.xuexi88.com/zhishi/index?page='+ (now+1)+'">；下一页</a>');
3、chrome浏览器运行index.html页面，此时会用js打印出上一页和下一页的a标签。
