在做网站没用 js ui控件时 很实用
用法:
var ps=new pagestring(); /*可选参数*/ ps.setisenglish = true;// 是否是英文 (默认:false) ps.setisshowtext = true;//是否显示分页文字 (默认:true) //ps.textformat="" (默认值:《span class=\"pagetext\"》《strong》总共《/strong》:{0} 条 《strong》当前《/strong》:{1}/{2}《/span》) //ps.setpageindexname request["pageindex"](默认值:"pageindex") ps.setisajax = false;// (默认值:"false") /*函数参数*/ int total = 10000; int pagesize = 10; int pageindex = convert.toint32(request["pageindex"]); var page = ps.tostring(total, pagesize, pageindex, "/ui/pagestringtest.aspx?"); //获取 page html 输出 response.write(page);
