>我在 while 循环中有名称为 2d 数组的单选按钮。我想显示单击时选中的单选按钮的数量。
我的单选按钮
$n=0;
while($row= mysqli_fetch_row($rs)){?>
<form name="myfm" id="myfm" method="post" action="Quizn.php">
<table width=100%> <tr> <td width=30><td></td></td></tr> <table border=0>
<?php $n=$n+1; ?>
<tr><td>Question <?php echo $n.") "; echo $row[2]; ?></td></tr>
<tr><td class=style8>A. <input type="radio" name="ques['<?php echo $n; ?>'][]" value=1><?php echo $row[3]; ?></td></tr>
<tr><td class=style8>B. <input type="radio" name="ques['<?php echo $n; ?>'][]" value=2><?php echo $row[4];?></td></tr>
<tr><td class=style8>C. <input type="radio" name="ques['<?php echo $n; ?>'][]" value=3><?php echo $row[5];?></td></tr>
<tr><td class=style8>D. <input type="radio" name="ques['<?php echo $n; ?>'][]" value=4><?php echo $row[6];?></td></tr>
<input type="hidden" name="ques['<?php echo $n; ?>'][]" value="0" />
<input type="hidden" value="<?php echo $row[0]; ?>" name="qid[]" />
<?php }
echo "<tr><td><input type=submit name=submit id='result' value='Get Result'></form>";
?>
</table></table>
</form>
<p>Clicked:</p> <p id="clicked">0</p>
JavaScript
$("input:radio").click(function () {
var totalRd = $('table').find(':not(.pend) > input:radio:checked').length;
$("#totalRd .rd-count").html(totalRd);
});
如果您知道解决方案，请帮助我。谢谢
有一些假设，尝试这样
<?php
if(isset($_POST['submit'])){
echo "<pre>";
print_r($_POST);
echo "</pre>";
}
?>
<form method="post" action="">
<?php for ($i=0; $i < 3 ; $i++) { ?>
<br>
A<input type="radio" name="ques[<?php echo $i;?>][]" value=1>
B<input type="radio" name="ques[<?php echo $i;?>][]" value=2>
C<input type="radio" name="ques[<?php echo $i;?>][]" value=3>
D<input type="radio" name="ques[<?php echo $i;?>][]" value=4>
<?php } ?>
<br>
<input type="submit" name="submit" value="submit">
</form>

我建议不要在这里使用数组name="ques[<?php echo $i;?>][]"而只是使用name="ques[<?php echo $i;?>]"来干净清晰
试试这个
$(":radio").on( 'click', function() {
count = $(':radio:checked').length;
alert(count);
});
