Answer 1

将表格结构更改为

<table id="info_table" class="table">
    <thead>
         <tr>
      <td><p align="center"><b>Ministry</b></p></td>
    </tr>
    <tr id="p1">  
      <td><p align="center"><b>Total ministries()</b></p></td>
    </tr>
   </thead>
   <tbody>
   </tbody>
  </table>

，然后将jQuery代码更改为

$('#info_table > tbody').append(info);

这真的很简单。只需定位您的元素<div role="tabpanel" class="tab-pane fade " id="tab3"> <div class="circular-div"> <table class="table table-striped table-hover" id="circular-table"> <thead> <tr> <th>ردیف</th> <th>دسته بندی</th> <th>عنوان</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>بخشنامه‌ها</td> <td>اطلاعیه جهاد دانشگاهی</td> </tr> <tr> <td>2</td> <td>بخشنامه‌ها</td> ... ... ...并将其HTML替换为您获得的值即可。
