jQuery函数closest仅返回第一行的值

Question

我正在使用的jQuery最近函数只返回记录的第一个值。请检查下面的代码。

<?php
$myLat = $f['mem_latitude'];
$myLng = $f['mem_longitude'];
$mySex = $f['mem_sex'];
$myPref = explode(',', $f['mem_preference']);

$users = $pdo->prepare("SELECT * FROM members WHERE mem_id != :mem AND mem_sex != :sex ORDER BY RAND() LIMIT 50");
$users-> bindValue(':mem', $sessionUser);
$users-> bindValue(':sex', $mySex);
$users-> execute();

$count = 0;
while($a = $users->fetch()) {
  $userLat = $a['mem_latitude'];
  $userLng = $a['mem_longitude'];
  $userAge = getAge($a['mem_dob']);
  $userSex = $a['mem_sex'];
  $userPref = explode(',', $a['mem_preference']);
  $distance = round(distance($myLat, $myLng, $userLat, $userLng, "K"));
  $distData = round(distance($myLat, $myLng, $userLat, $userLng, "K"))." kms away";
  $geo = unserialize(file_get_contents("http://www.geoplugin.net/extras/location.gp?lat=$userLat&lon=$userLng&format=php"));

  if($distance < 1500) {
    if((in_array($mySex, $userPref)) && (in_array($userSex, $myPref))) {
            $count++;
?>

          <small><?php echo "".$geo['geoplugin_place'].", ".$geo['geoplugin_region'].", ".$geo['geoplugin_countryCode'].""; ?></small>

        </div>
        </div>
            <form class="cardform">
                <input type="text" value="<?php echo $a['mem_id']; ?>" class="hidden">
            </form>
  </div>
<?php } } } ?>

<script>
//Swipe active card to left.
function onSwipeLeft() {
    var hidid = $(".cardform").closest('form').find('.hidden').val();
    // console.log(hidid);
    alert(hidid);
    removeNoTransition();
    transformUi(-1000, 0, 0, currentElementObj);
    if(useOverlays){
        transformUi(-1000, 0, 0, leftObj); // Move leftOverlay
        transformUi(-1000, 0, 0, topObj); // Move topOverlay
        resetOverlayLeft();
    }
    currentPosition = currentPosition + 1;
    updateUi();
    currentElement();
    changeBackground();
    changeStages();
    setActiveHidden();
};
</script>

在这里，alert(hidid)只返回第一行的值。我一遍又一遍地检查，但在我看来一切都是对的。然而，这并不明显。请帮我纠正这个问题。

Answer 1

查看该库后，可以看到currentElementObj是当前活动卡存储的位置。然后，我们可以从这个对象中找到表单和隐藏字段，如下所示：

 //Swipe active card to left.
        function onSwipeLeft() {
            var hidid = $(currentElementObj).find('form .hidden').val();
            // console.log(hidid);
            alert(hidid);
            removeNoTransition();
            transformUi(-1000, 0, 0, currentElementObj);
            if(useOverlays){
                transformUi(-1000, 0, 0, leftObj); // Move leftOverlay
                transformUi(-1000, 0, 0, topObj); // Move topOverlay
                resetOverlayLeft();
            }
            currentPosition = currentPosition + 1;
            updateUi();
            currentElement();
          changeBackground();
          changeStages();
            setActiveHidden();
        };

Answer 2

您的问题是jQuery函数.val()只返回您选择的第一个元素的值。

您必须对表单中的所有隐藏元素执行$.each()操作，并将值放入一个数组中，然后才能在alert()中输出它们

代码示例

var array = [];
$('.cardform').find('.hidden').each(function(index, element) {
    array[index] = $(element).val();
})
alert(array);
