Question

我在页面中有4个动态添加的radiobuttonlist。我要检查一下其中一个选项在jquery中检查了其中4个。怎么做到呢？我尝试在c＃中的每个radiobuttonlist中添加相同的类（＆＃34; rb1＆＃34;）并尝试使用以下代码，但无法获得所需的结果。

$('table.rb1 input:radio').each(function () {
     var checked = $(this).find('input:radio:checked');
     if (checked.length == 0) {
         alert("All questions are mandatory !!! ")
         result = false;
         return;
     }
 });

Html代码如下：

<table id="ctl00_ContentPlaceHolder1_ctl34" class="rb1" border="0">
    <tr>
        <td>
            <input id="ctl00_ContentPlaceHolder1_ctl34_0" type="radio" name="ctl00$ContentPlaceHolder1$ctl34" value="1" />
            <label for="ctl00_ContentPlaceHolder1_ctl34_0">excellent</label>
        </td>
        <td>
            <input id="ctl00_ContentPlaceHolder1_ctl34_1" type="radio" name="ctl00$ContentPlaceHolder1$ctl34" value="2" />
            <label for="ctl00_ContentPlaceHolder1_ctl34_1">good</label>
        </td>
        <td>
            <input id="ctl00_ContentPlaceHolder1_ctl34_2" type="radio" name="ctl00$ContentPlaceHolder1$ctl34" value="3" />
            <label for="ctl00_ContentPlaceHolder1_ctl34_2">average</label>
        </td>
        <td>
            <input id="ctl00_ContentPlaceHolder1_ctl34_3" type="radio" name="ctl00$ContentPlaceHolder1$ctl34" value="4" />
            <label for="ctl00_ContentPlaceHolder1_ctl34_3">not relevant</label>
        </td>
    </tr>
</table>

您只需检查每个length table.rb1 input[type="radio"]:checked的{{1}}是否等于0：

table

$('#check').on('click',function(){
  $('table.rb1').each(function(){
    if($('input[type="radio"]:checked',this).length == 0) alert('None checked');
  });
});

$('#reset').on('click',function(){
  $('table.rb1 input[type="radio"]').prop('checked',false);
});

检查是否在jquery中的动态radiobuttonlist中选择了一个选项
