ASP.NET MVC+Bootstrap个人博客之打造清新分页Helper（三）

0.　没有找到一款中意的分页插件，又不想使用现成的(丑到爆)，所以自己动手造一个吧

先看下效果(其实也不咋滴...)：

有点另类，分页直接是在后台拼接好html，然后发送到前台的：

1. 分页容器：

<div class="pagination"><ul>//************分页HTML*********</ul>
</div>

2.  PagerHelper：

namespace ZYN.BLOG.WebHelper
{public class PagerHelper{/// <summary>/// 生成分页Html数据/// </summary>/// <param name="currentPage">当前页</param>/// <param name="pageSize">页容量</param>/// <param name="totalCount">数据总条数</param>/// <returns>pagerHtmlString</returns>public static string GeneratePagerString(int currentPage, int pageSize, int totalCount){var redirectToUrl = HttpContext.Current.Request.Url.AbsolutePath;pageSize = pageSize <= 0 ? 4 : pageSize;//1.0 总页数int totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1);//2.0 分页条的容量int pageBarSize = 6;//默认一个分页条显示6个页码。分页条容量 //3.0 分页条的个数 totalPages个页数按 pageBarSize = 6  可以 分为多少个分页条int pageBarNum = (totalPages + pageBarSize - 1) / pageBarSize; // totalPages=13时，也就是把13个页码分成3个分页条//判断当前页currentPage坐落在第几个分页条内int position = (currentPage - 1) / pageBarSize;  //根据分页条的序号，计算出该分页条的第一个页码start和最后一个页码endint start = position * pageBarSize + 1;//如果是最后一个分页条，则需判断它实际的页条容量；否则页条容量就是pageBarSizeint curBarCapacity = pageBarSize;if (position == pageBarNum - 1){curBarCapacity = totalPages - (pageBarNum - 1) * pageBarSize;}StringBuilder pagerHtmlString = new StringBuilder();StringBuilder endHtmlString = new StringBuilder();//处理首页pagerHtmlString.AppendFormat("<li id='start-page'><a href='{0}?pageIndex={1}&pageSize={2}'>首页</a></li> ", redirectToUrl, 1, pageSize);//处理上一页:如果当前页不是第一页,就加上上一页if (currentPage > 1){pagerHtmlString.AppendFormat("<li class='prev-page'><a href='{0}?pageIndex={1}&pageSize={2}'>上一页</a></li> ", redirectToUrl, currentPage - 1, pageSize);}//假如起始位置start为1  7  13for (int i = 0; i < curBarCapacity; i++)  //curBarCapacity=3  i=0 1 2
            {int j = start + i; //要显示的页码当量值if (j == currentPage){//对当前页的处理:class=activepagerHtmlString.AppendFormat("<li class='active show-page'><span>{0}</span></li> ", currentPage);if (curBarCapacity == pageBarSize){//不处理最后一个分页条页if (currentPage == start + pageBarSize - 1){if (currentPage + 1 < totalPages){endHtmlString.AppendFormat("<li class='show-page'><a href='{0}?pageIndex={1}&pageSize={2}'>{3}</a></li>", redirectToUrl, currentPage + 1, pageSize, currentPage + 1);}endHtmlString.Append("<li class='show-page'><span>...</span></li>");endHtmlString.AppendFormat("<li class='show-page'><a href='{0}?pageIndex={1}&pageSize={2}'>{3}</a></li>", redirectToUrl, totalPages, pageSize, totalPages);}}}else{pagerHtmlString.AppendFormat("<li class='show-page'><a href='{0}?pageIndex={1}&pageSize={2}'>{3}</a></li> ", redirectToUrl, j, pageSize, j);}}//省略号的处理
            pagerHtmlString.Append(endHtmlString.ToString());//处理下一页：如果当前页不是最后一页，则加上下一页。也即中间的所有分页条都显示下一页if (currentPage != totalPages){pagerHtmlString.AppendFormat("<li class='next-page'><a href='{0}?pageIndex={1}&pageSize={2}'>下一页</a></li> ", redirectToUrl, currentPage + 1, pageSize);}//处理末页pagerHtmlString.AppendFormat("<li id='end-page'><a href='{0}?pageIndex={1}&pageSize={2}'>末页</a></li> ", redirectToUrl, totalPages, pageSize);pagerHtmlString.AppendFormat("<li id='total-page'><span>共-{0}-页</span></li>", totalPages);pagerHtmlString.Append(" ");return pagerHtmlString.ToString();}}
}

3 渲染出来的分页HTML是这样的：

<div class="pagination"><ul>
　　　　<li id="start-page"><a href="/Home/WrapArtList/0?pageIndex=1&amp;pageSize=6">首页</a></li> 
　　　　<li class="active show-page"><span>1</span></li> 
　　　　<li class="show-page"><a href="/Home/WrapArtList/0?pageIndex=2&amp;pageSize=6">2</a></li> 
　　　　<li class="show-page"><a href="/Home/WrapArtList/0?pageIndex=3&amp;pageSize=6">3</a></li>
　　　  <li class="show-page"><a href="/Home/WrapArtList/0?pageIndex=4&amp;pageSize=6">4</a></li> 
　　　　<li class="show-page"><a href="/Home/WrapArtList/0?pageIndex=5&amp;pageSize=6">5</a></li>
　　　  <li class="next-page"><a href="/Home/WrapArtList/0?pageIndex=2&amp;pageSize=6">下一页</a></li>
　　　　<li id="end-page"><a href="/Home/WrapArtList/0?pageIndex=5&amp;pageSize=6">末页</a></li> 
　　　　<li id="total-page"><span>共-5-页</span></li> 
   </ul>
</div>

4. CSS样式：

/* 分页样式pagination ====== */
.pagination { /* div pagination*/margin: 0;padding: 20px;text-align: center;font-size: 12px;display: block;
}.pagination ul {display: inline-block;*display: inline;*zoom: 1;margin-left: 0;margin-bottom: 0;padding: 0;}.pagination ul > li {display: inline;}.pagination ul > li > a,.pagination ul > li > span {margin: 0 2px;float: left;padding: 5px 12px;background-color: #ddd;color: #666;border-radius: 2px;opacity: .88;}.pagination ul > li > a:hover,.pagination ul > li > a:focus {background-color: #bce8f1;}.pagination ul > .active > a,.pagination ul > .active > span {background-color: #45B6F7;color: #fff;}.pagination ul > .active > a,.pagination ul > .active > span {cursor: default;}.pagination ul > li > span,.pagination ul > .disabled > span,.pagination ul > .disabled > a,.pagination ul > .disabled > a:hover,.pagination ul > .disabled > a:focus {color: #999999;background-color: transparent;cursor: default;}
/* 自定义的分页pagination 结束====== */
