我有一个简单的相关选择问题。我有一个cfdiv绑定到cfm与选择输入。
选择＆＃34;工作＆＃34;正确地说，您从第一个选择中选择一个类别，它会更改第二个选择的值。但spec_id不是邮件形式。
这可能很简单。想法？

答案 0 :(得分：3)
您的<form>无效地嵌套在</tr><tr>之间。将它移到<table>标记之外，它应该可以正常工作。
像这样:(为了清楚起见，请注意剥离）
<table width="95%" align="center" cellspacing="5" border="0">
<tr>
<td width="50%">
<form action="cfdivtest.cfm" method="post" name="specForm" id="specForm">
<table cellpadding="3" width="100%" cellspacing="1" class="form">
<tr><td colspan="7" class="page_subTitle">Spec Sets</td></tr>
<tr>
<td class="grid_head">Set ID</td>
<td class="grid_head">Set Name</td>
<td class="grid_head">Event</td>
<td class="grid_head">Public</td>
<td class="grid_head">Standard</td>
<td class="grid_head" align="center">Edit</td>
<td class="grid_head" align="center">Delete</td>
