我有一个56000条记录的数据库，我需要实现数据表服务器端代码。问题是我已经完成了完成这项任务的所有必要步骤，但仍然徒劳无功，给我提供了全套数据。
主要问题是当我的页面加载时，它会在运行时加载所有56000条记录，并导致页面在非结束状态下停止。
因此，一旦数据表正确实现，这个问题就会自动发生。 我希望在运行时完成此操作。 页面加载后，它应显示分页并拆分页面中的所有56000条记录。限制应该是50。
搜索和排序也无效。
这是我的JS功能：
<link href="//cdn.datatables.net/1.10.0/css/jquery.dataTables.css" rel="stylesheet" type="text/css" />
<script src="http://legacy.datatables.net/release-datatables/media/js/jquery.js"></script>
<script src="//legacy.datatables.net/release-datatables/media/js/jquery.dataTables.js"></script>
<script type="text/javascript" language="javascript" class="init">
$(document).ready(function() {
$('#rounded-corner').dataTable( {
"processing": true,
"serverSide": true,
"ajax": "<?php echo WEB_URL; ?>assets/common/authorsServerSide.php",
} );
} );
</script>
这是我的HTML代码：
<table id="rounded-corner" summary="2007 Major IT Companies' Profit" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th scope="col" class="rounded-company">Sr No.</th>
<th scope="col" class="rounded">Author Name</th>
<th scope="col" class="rounded">Birth Year</th>
<th scope="col" class="rounded">Death Year</th>
<th scope="col" colspan="2" class="rounded-q4">Action</th>
</tr>
</thead>
<tbody>
<?php $count = 1; while($AuthorRecs = $RecordSet->fetch_object()){?>
<tr>
<td><?php echo $count++; ?></td>
<td><?php print stripslashes(html_entity_decode($AuthorRecs->a_name)); ?></td>
<td><?php print $AuthorRecs->a_birth; ?></td>
<td><?php print $AuthorRecs->a_death; ?></td>
<td><a href="editAuthors?a_ID=<?php echo $AuthorRecs->a_ID; ?>"><img src="../assets/styles/admin/images/user_edit.png" alt="" title="" border="0" /></a></td>
<td><a href="process/adminProcess.php?page=deleteAuthors&a_ID=<?php echo $AuthorRecs->a_ID; ?>" class="ask"><img src="../assets/styles/admin/images/trash.png" alt="" title="" border="0" /></a></td>
</tr>
<?php } ?>

看起来数据表函数的最后一行有一个额外的逗号。 “”

您缺少应用搜索的脚本：
table.columns().every(function () {
var that = this;
$('input', this.footer()).on('keyup change', function () {
if (that.search() !== this.value) {
that.search(this.value).draw();
}
});
});
