点击按钮“删除”,如果选择了没有单选按钮如何显示一个警告后。我的html表格显示警报()如果没有单选按钮被选中
<form name="Action" method="post" action="RequestAction">
<table width="800px" cellpadding="5" style="color:black; border-top:1px solid #ccc;" border="0">
</table>
<div id="container">
<div id="demo_jui">
<table id="requestList" class="display" cellpadding="0" cellspacing="0" border="0" style="font-size:12px;" >
<thead id="headed">
<tr>
<th align="center" title="Employee">Employee</th>
<th align="center" title="Number of Days">Number of Days</th>
<th align="center" title="Start Date">Start Date</th>
<th align="center" title="End Date">End Date</th>
<th align="center" title="Leave Type">Leave Type</th>
<th align="center" title="Remark">Remark</th>
<th align="center">Approve</th>
<th align="center">Reject</th>
</tr>
</thead>
<tbody></tbody>
</table>
</div>
</div>
<table>
<tr>
<td style="padding-left:0px;" colspan="3">
<a href="#"><img src="images/Submit.png" style="border:none;" onClick="javascript:Go()"
onmouseover="this.src='images/Submit_Hover.png'" onmouseout="this.src='images/Submit.png'"/></a>
<a href="#"><img src="images/Reset.png" style="border:none;" onClick="javascript:clearForm()"
onmouseover="this.src='images/Reset_Hover.png'" onmouseout="this.src='images/Reset.png'"/></a>
</td>
</tr>
</table>
</form>
单选按钮值将在表格中检索。当我测试了一下,如果没有点击任何选择单选按钮提交按钮,我会得到错误
在功能围棋(),是这样的验证单选按钮是否正确?谢谢
function Go() {
if($('form[name=Action] input[name=statusList]:checked').length == 0)
{
$('form[name=Action]').submit();
}
else
{
alert("Please select at least one to delete");
}
}
你的HTML不会出现任何复选框或输入的。此外,你的JavaScript似乎是倒退的,因为你的条件只在没有检查输入时才提交。此外,Java和异常堆栈跟踪与问题无关。 –
