Question

首先，我不知道如何指定标题抱歉。

我有一个相当混乱的代码，但基本上这是它应该做的。按下删除按钮时，整个tr应该消失。目前只有最后一个带有按钮的td消失了。我试着替换

中的a

$('a').click(function(){

与tr。但是当我这样做时，行将消失，但它不会在数据库中删除。有谁知道溶剂？提前致谢

ps：对不起我的英文和严重显示的编码。

$safeid = mysql_real_escape_string($id);
$query = mysql_query("delete from units where id=$id", $con);

当您找到a的父级时，您会找到td。这可以解释为什么您看到td消失而不是tr。

因此，请使用parent()代替closest("tr")而不是//var parent = $(this).parent(); var parent = $(this).closest("tr");：

parent

然后slideUp / remove parent ...然后您可能还想将parentRow重命名为id。

删除数据库中的数据。您的代码似乎正在尝试查找a的{{1}}属性，因此您需要确保id中的a属性与<a href="#" id="<?php echo $row['id']; ?>" ... />匹配id你想要从db中删除...类似于$('document').ready(function () { $('tr').click(function () { //this assumes id will always be within the first td //you could also put classes on your td's to identify var del_id = $(this).find("td").first().text(); var row = $(this); $.post('delete.php', { id: del_id }, function (data) { row.slideUp('slow', function () { row.remove(); }); }); }); });

另一个解决方案，如果您希望能够点击该行中的任何位置（因为您提到尝试过），您可以这样做：

{{1}}

Javascript从数据库中删除/淡化表行
