Question

我有六个单选按钮，其id正在foreach循环中动态变化，现在我必须在foreach循环之外获取该值。如果有任何机构比解知道，请帮助。下面是我的代码

<div class="person_option-block">
    <h5>No of Person</h5>
    <?php
        $no_of_persons = $this->Mdl_home->no_of_person_all();
        foreach($no_of_persons as $no_of_person){ ?>
    <label class="person_option">
        <?php echo $no_of_person['person']; ?> 
        ($ <?php echo $no_of_person['price']; ?>/person)
        <input type="radio" class="person-radio" name="no_person" id="<?php echo $no_of_person['id']; ?>" value="<?php echo $no_of_person['id']; ?>"
            onchange="get_makeup_service(<?php echo $no_of_person['person']; ?>)">

        <input type="hidden" id="person_<?php echo $no_of_person['person']; ?>" value="<?php echo $no_of_person['person']; ?> ($<?php echo $no_of_person['price']; ?>/person)">
    </label>
    <?php } ?>
</div>
<div class="pull-right">
    <a href="javascript:void(0);" class="custom-btn" id="step1-next-btn">
        Next
        <i class="fa fa-angle-double-right" aria-hidden="true"></i>
    </a>
</div>

当我单击下一步按钮时，特定单选按钮的ID应发出警报

$('#step1-next-btn').click(function(){ 
    $('#step1-block').hide();
    $('#step2-block').show();
});

Answer 1

使用$('input[name=no_person]:checked').val();表达式获取选定的单选按钮值。

Answer 2

尝试使用，

$（function（）{

if（$（“＃radioID”）。prop（“ checked”））{

SELECT COLUMN_NAME 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = 'MyTable' AND COLUMN IS NOT EMPTY

}

}）;
