jQuery函数不知道选择哪个选项来移动

Question

我正在使用jQuery向下滑动并基于无线电选择向上滑动<div>。

然后，我有一些PHP代码，记得设置了什么选项，所以如果用户浏览和从页面导航，它会记住，如果他们有“隐藏框”。

该代码昨天工作，但似乎今天没有工作。我试过调试但没有运气。

的jQuery：

$('.children-under-18-yes').click(function(){ 
    $('.children-guardians').slideDown(); 
}); 
$('.children-under-18-no').click(function(){ 
    $('.children-guardians').slideUp(); 
}); 

PHP/HTML

<h2>Are any of the children under 18 years old?</h2> 
    <li> 
     <label class="radio"><input type="radio" name="children_under_18" id="children_under_18" group="underage" class="children-under-18-yes" value="yes"<?php echo stickyRadio('children_under_18','yes');?> />Yes</label> 
     <label class="radio"><input type="radio" name="children_under_18" id="children_under_18" group="underage" class="children-under-18-no" value="no"<?php echo stickyRadio('children_under_18','no');?> />No</label> 
    </li> 
    <br class="clear" /> 

    <div class="children-guardians"<?php echo isset($_SESSION['chidren_under_18']) && $_SESSION['chidren_under_18'] != 'no' ? 'style="display: block;"' : 'style="display: none;"' ?>> 
     <h3>As you answered yes, please provide the names of those persons you want to serve as guardians of your minor child(ren) in the event of your death. </h3> 

     <li> 
      <label class="float">1st Choice Guardian</label> 
      <input type="text" name="1st_guardian" id="1st_guardian" value="<?php echo stickyText('1st_guardian'); ?>" /> 
     </li> 

     <li> 
      <label class="float">2nd Choice Guardian</label> 
      <input type="text" name="2nd_guardian" id="2nd_guardian" value="<?php echo stickyText('2nd_guardian'); ?>" /> 
     </li> 
    </div> 

会议发布（从页）

if(empty($missing)) { 
    post2session(array('children')); 
    $_SESSION['step'][2] = 2; 
    if(isset($url)) { 
     redirect($url); 
    } 
} 

会后功能

 function post2session($parts = array()) { 

    $out = array(); 

    foreach($_POST as $key => $value) { 
     $value = is_array($value) ? $value : trim($value); 
     $par = explode("#",$key); 
     if(in_array($par[0],$parts)) { 
      $out[$key] = $value; 
     } else { 
      $_SESSION[$key] = $value; 
     }  
    } 

    if(!empty($out)) { 

     foreach($_SESSION as $key => $value) { 
      $par = explode("#",$key); 
      if(in_array($par[0],$parts) && !array_key_exists($key,$out)) { 
       unset($_SESSION[$key]); 
      } 
     } 

     foreach($out as $key => $value) { 
      $_SESSION[$key] = $value; 
     } 

    } else { 

     foreach($_SESSION as $key => $value) { 
      $par = explode("#",$key); 
      if(in_array($par[0],$parts)) { 
       unset($_SESSION[$key]); 
      } 
     } 

    } 

}

您正在验证的会话变量的名称与无线电控制的名称不匹配（chidren_under_18与chi * l * dren_under_18）。
