大家在作分页时，多数是在后台返回一个导航条的html字符串，其实在前端用js也很好实现。
调用pager方法，输入参数，会返回一个导航条的html字符串。方法的内部比较简单。
1 /** 2 * pageSize, 每页显示数 3 * pageIndex, 当前页数 4 * pageCount 总页数 5 * url 连接地址 6 * pager(10, 1, 5, 'Index')使用方法示例 7 */ 8 function pager(pageSize, pageIndex, pageCount, url) { 9 var intPage = 7; //数字显示 10 var intBeginPage = 0;//开始的页数 11 var intEndPage = 0;//结束的页数 12 var intCrossPage = parseInt(intPage / 2); //显示的数字 13 14 var strPage = "<div class='fr'><span class='pageinfo'>第 <font color='#FF0000'>" + pageIndex + "/" + pageCount + "</font> 页 每页 <font color='#FF0000'>" + pageSize + "</font> 条</span>"; 15 16 if (pageIndex > 1) { 17 strPage = strPage + "<a class='pageNav' href='" + url + "?pageIndex=1&pageSize=" + pageSize + "'><span>首页</span></a> "; 18 strPage = strPage + "<a class='pageNav' href='" + url + "?pageIndex=" + (pageIndex - 1) + "&pageSize=" + pageSize + "'><span>上一页</span></a> "; 19 } 20 if (pageCount > intPage) {//总页数大于在页面显示的页数 21 22 if (pageIndex > pageCount - intCrossPage) {//当前页数>总页数-3 23 intBeginPage = pageCount - intPage + 1; 24 intEndPage = pageCount; 25 } 26 else { 27 if (pageIndex <= intPage - intCrossPage) { 28 intBeginPage = 1; 29 intEndPage = intPage; 30 } 31 else { 32 intBeginPage = pageIndex - intCrossPage; 33 intEndPage = pageIndex + intCrossPage; 34 } 35 } 36 } else { 37 intBeginPage = 1; 38 intEndPage = pageCount; 39 } 40 41 if (pageCount > 0) { 42 for (var i = intBeginPage; i <= intEndPage; i++) { 43 { 44 if (i == pageIndex) {//当前页 45 strPage = strPage + " <a class='current' href='javascript:void(0);'>" + i + "</a> "; 46 } 47 else { 48 strPage = strPage + " <a class='pageNav' href='" + url + "?pageIndex=" + i + "&pageSize=" + pageSize + "' title='第" + i + "页'>" + i + "</a> "; 49 } 50 } 51 } 52 } 53 54 55 if (pageIndex < pageCount) { 56 strPage = strPage + "<a class='pageNav' href='" + url + "?pageIndex=" + (pageIndex + 1) + "&pageSize=" + pageSize + "'><span>下一页</span></a> "; 57 strPage = strPage + "<a class='pageNav' href='" + url + "?pageIndex=" + pageCount + "&pageSize=" + pageSize + "'><span>尾页</span></a> "; 58 } 59 return strPage+"</div>"; 60 61 }
试用这个方法试试

看下效果
列有点多，我只截图了部分，界面好丑，加点样式，用bootstrap来美化下
使用Nuget安装bootstrap
加上样式后
虽说不是特别漂亮，但还是对得起观众吧。
