此分頁控件支持URL附加參數方式,比如說 xx?page=1 這種方式,
亦能實現自定義的URL得寫方式,比如說 news-list-1(分頁碼).Html
支付中英文兩種界面顯示方式,
對應CSS文件為:
1 .Pagination a{display:block;padding:1px 6px; border:1px solid #14A7FF;float:left;margin-left:2px;color:#14A7FF;font:normal 12px 'Arial'}
2 .Pagination a:hover{background:#14A7FF;color:#fff;border:1px solid #14A7FF;}
3 .Pagination a.curr{color:#CB05F5;background:#fff;border:1px solid #CB05F5;}
4 .Pagination a.curr:hover{color:#CB05F5;background:#fff;border:1px solid #CB05F5;}
5 .Pagination a.noboder{display:block;padding:1px 6px;float:left;margin-left:2px;border:0;}
6 .Pagination a.noboder:hover{display:block;padding:1px 6px;float:left;margin-left:2px;border:0;background:none;}
7 .Pagination span{float:left;margin:3px 6px 0 0;display:block;}
調用方式為:
1 <div class="Pagination">@Html.Pagination((int)ViewBag.PageSize, (int)ViewBag.Index, (int)ViewBag.RecordCount, new { @ViewType = 0, @IdentifIEr = "page", @Encrypt = false })</div>
具體參數為:
/*
* <span>共：{RecordCount}條 {PageSize}條/頁 {CurrentPage}頁/{PageCount}頁</span> {List}
* <span>Page {CurrentPage} of {PageCount} ({RecordCount} items) PageSize：{PageSize}</span> {List}
* @VIEwType = 0, 0中文 1英文 2自定義中文 3自定義英文
* @Template = "<span>共：{RecordCount}條 {PageSize}條/頁 {CurrentPage}頁/{PageCount}頁</span> {List}",
* @Postfix = "",
* @VirtualPath = "",
* @IdentifIEr = "page",
* @Encrypt = false }
*/
