<script type="text/javascript" src="js/tablecloth.js"></script><br />
<?php<br />
require('inc/page.class.php');<br />
require("inc/pdo.php");<br />
$selectSpecialContent=$dbc->prepare("select * from naszt");<br />
$selectSpecialContent->execute();<br />
?><br />
<table align="center" cellspacing="0" cellpadding="0"><br />
<tr><br />
<th>专题名称</th><br />
<th>专题类型</th><br />
<th>发表时间</th><br />
<th>发表ip</th><br />
<th>操作</th><br />
</tr><br />
<?php while($row=$selectSpecialContent->fetch()){ ?><br />
<tr id="<?php echo $row['id']?>"><br />
<td><?php echo $row['ztname']?></td><br />
<td><?php echo $row['zttype']?></td><br />
<td><?php echo $row['zttime']?></td><br />
<td><?php echo $row['publiship']?></td><br />
<td><button><a href="ztselect.php?id=<?php echo $row['id']?>">查看</a></button><button><a href="upzt.php?act=up&id=<?php echo $row['id']?>">修改</a></button><button id="del"><a href="selectzt.php?act=del&id=<?php echo $row['id']?>">删除</a></button></td><br />
</tr><br />
<?php }; ?><br />
</table><br />
<script><br />
$(document).ready(function(){<br />
$("#del").click(function(){<br />
var q=$("tr").attr("id");<br />
alert(q);<br />
});<br />
});<br />
</script>

本来是想在tr 加个id  获取到这个id的值删除本行  但好像不行,请教高手

简单的改了下，你看看效果和做法

<script><br />
$(function() {<br />
  $('.del').click(function() {<br />
    $('#'+$(this).attr('id')).remove();<br />
  });<br />
});<br />
</script><br />
<table align="center" cellspacing="0" cellpadding="0"><br />
<tr><br />
<th>专题名称</th><br />
<th>专题类型</th><br />
<th>发表时间</th><br />
<th>发表ip</th><br />
<th>操作</th><br />
</tr><br />
<tr id="1"><br />
<td>$row['ztname']</td><br />
<td>$row['zttype']</td><br />
<td>$row['zttime']</td><br />
<td>$row['publiship']</td><br />
<td><a href="?id=1">查看</a><button><a href="?act=up&id=1">修改</a></button><button class='del' id=1>删除</button></td><br />
</tr><br />
</table><br />
<?php<br />
print_r($_GET);
