一个通用的JavaScript分页
1.JavaScript代码
- Pagination=function(id)
- {
- var totalNum=0;

- currentpage = parseInt(currentpage);
- }
- var pagecount = Math.floor(count/perpage)+1;
- var pagestr = "";
- var prevnum = currentpage-currentposition;
- var nextnum = currentpage+currentposition;
- if(prevnum<1) prevnum = 1;
- if(nextnum>pagecount) nextnum = pagecount;
- pagestr += (currentpage==1)?'<span class="disabled"> <上一页</span>':'<span><a href="javascript:'+pageName+'.page_onclick('+(this.getIndexPage()-1)+',\''+pageName+'\')"><上一页</a></span>';
