Question

我已经使用下面的代码进行表格分页，包括bootstrap提供的javascript。我在分页中有三个链接，"1", "2", "3"将在表格下打开相应的行数，当我在打开页面后点击下一个按钮"3", "1"应该被"4", "2"替换"5"和"3" "6"，

这些是我的JS和html文件

$(document).ready(function(){

  $('#myTable').pageMe({pagerSelector:'#myPager',showPrevNext:true,hidePageNumbers:false,perPage:2});

});

请帮忙

Answer 1

当您执行$('#myTable').pageMe(...)时，listElement.children();会找到<thead>和<tbody>元素。

使用$('#myTable tbody')查找<tr>元素。

使用bootstrap的表分页不起作用
