我有一个服务器端数据表，上面有一个复选框。
当我检查一个复选框并转到另一个页面或我搜索某个值并返回检查消失时。
如何使此复选框保持选中状态？
我使用的是php，我的视图部分是
<table class="table table-striped table-bordered bootstrap-datatable datatable" path="result/mark-list-json/<?php echo $selected_exam; ?>/" id="servertable123"><!--table starts-->
<thead>
<tr>
<th width="5%">Sl</th>
<th width="7%">Reg No</th>
<th width="7%">Name</th>
<th width="10%">School</th>
<th width="10%">Mark</th>
<th width="5%">Rank</th>
<th width="5%">Publish</th>
</tr>
</thead>
</table>
