Question

我有一个值列表，超链接'onclick'将在下面的数组中显示相关的记录集。

通过PHP，我有连接表值的数据集。现在我需要将该数据集链接到onclick事件。

通过我的研究，有几种方法可以解决这个问题：iFrames（似乎不推荐）; JSON / AJAX（我不知道的语言，我的其他数据都不使用这种结构，但可以直接使用PHP吗？）;

带有相关函数的$ _ GET变量似乎是一种方法，但我正在努力获得正确的语法来创建响应。这会使用过滤功能吗？

本质上：$ row_artistrecordset ['artist'] = $ row_getartists ['artist']。如果我可以在这个匹配结构上建立代码，那么它将具有足够的通用性，可以用于其他页面。

到目前为止，这是我的代码：

<?php
mysql_select_db($database_connectmysql, $connectmysql);
$query_artistrecordset = "SELECT * FROM artists ORDER BY artist ASC";
$artistrecordset = mysql_query($query_artistrecordset, $connectmysql) or die(mysql_error());
$row_artistrecordset = mysql_fetch_assoc($artistrecordset);
$totalRows_artistrecordset = mysql_num_rows($artistrecordset);
 ?>

您希望在用户点击某些内容时执行操作。假设您有一个值表，并且希望获得有关值的更多信息。 html可能如下所示：

<table width=100% cellpadding=0 cellspacing=0>
<tr>
<td width=30% valign=top><span onclick="alert('Value 1 was clicked');">1</span></td>
<td width=70% valign=top>Description of Value 1</td>
</tr>
<tr>
<td width=30% valign=top><span onclick="alert('Value 2 was clicked');">1</span></td>
<td width=70% valign=top>Description of Value 2</td>
</tr>
</table>

这里会发生的是当您单击表格的最左边两列中的任何一列时，将调用javascript alert（）函数。

您也可以将信息传递给您自己的脚本，如：

    <script>
    function myOwnAlert(value) {
         alert(value);
    }
    </script>
<div id="myTable">
    <table width=100% cellpadding=0 cellspacing=0>
    <tr>
    <td width=30% valign=top><span onclick="myOwnAlert('Value 1 was clicked');">1</span></td>
    <td width=70% valign=top>Description of Value 1</td>
    </tr>
    <tr>
    <td width=30% valign=top><span onclick="myOwnAlert('Value 2 was clicked');">1</span></td>
    <td width=70% valign=top>Description of Value 2</td>
    </tr>
    </table>
</div>

净效果相同，显示了一条消息。但是，您也可以使用jQuery动态更新表。有很多关于jQuery的在线教程。您将基本上使用javascript函数，例如：

<script>
function myOwnAlert(value) {
    $.post("getnewtable.php",'v=' + value, function(data) {
          $("#myTable").html().trigger("create");
    });
}
</script>

这将导致表的内容被getnewtable.php脚本的输出替换。

注意：这并不是使用HTML或jQuery的主要示例 - 只是一个非常小的教程。
