Beispiel für nicht aktualisiertes Tabellen-Paging basierend auf jQuery_jquery

Das Beispiel in diesem Artikel beschreibt das nicht aktualisierende Tabellen-Paging basierend auf jQuery. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:

Die Darstellung ist wie folgt:

HTML-Struktur:

<table id="cs_table" class="datatable"></table>

CSS-Stil:

html,body{margin: 0;padding:0}
a:focus {outline: none;}
/* 通用表格显示 */
table, th, td {font: 12px Arial,Helvetica,sans-serif,'宋体';margin: 0;padding: 0}
table{border-spacing: 0;border-collapse: collapse;}
.datatable {width: 100%;border-style: none;background-color: #fff;margin-bottom: 20px;text-align: left;}
.datatable th, .datatable td { padding: 5px;line-height: 30px}
.datatable thead th {background-color: #eee;margin: 0;text-align: left;border-top: 1px solid #cfcfcf;border-bottom: 1px solid #cfcfcf;font-weight: 500}
.datatable tbody td {background-color: #fff;border-bottom: 1px solid #ddd;table-layout:fixed;word-break:break-all;font-weight: 400}
.datatable tbody tr.evenrow td {background-color: #f4f4f4;}
.datatable tfoot td {background-color: #fafafa;text-align: right;border-bottom: 1px solid #cfcfcf;}
/*表格分页列表*/
.datatable td.paging a {border: 1px solid #eee; color: #444; margin: 4px; padding: 2px 7px; text-decoration: none; text-align:center;}
/*表格分页当前页*/
.datatable td.paging a.current {background: #eee; border: 1px solid #CFCFCF; color: #444; font-weight: bold;}
.datatable td.paging a.current{border: 0;cursor: auto;background:none}
