评论和子评论形式：在 while 循环 (php) 中显示和隐藏它时出现问题，并且基于 jquery 脚本逻辑

Question

问题出在我的两个表单上（用于用户的评论和子评论）。我已经实现了 jquery 代码，以便在单击 "reply" 按钮时可以显示或隐藏此表单。好吧，伙计，到目前为止一切顺利。但我注意到，经过几次测试后，这对评论有效，但对子评论无效。

它在子评论上有效，但仅在我发布的子评论和我登录自己的系统时有效。在其余的子评论上，它不起作用，当我单击辅助评论或子评论 "reply" 按钮时，它不显示或隐藏任何内容，其他按钮如 "delete" 和 "edit" 看起来不活跃，根本不工作。嗯，这是我的第一个问题。现在，我的第二个问题是跨度 "view replies".

当我点击它时，它会立即隐藏所有带有 class“.replies”的 "ul"（无序列表）（其中有主评论的子评论）而不是一个像我喜欢的那样（隐藏和显示切换）。此外，当我再次单击它时，它根本不会重新显示。这是 jQuery 代码：

$(document).ready(function(){
  $(document).on('click' , '.reply' , function(){
     var closestDiv = $(this).closest('div'); // also you can use $(this).parent()
     //closestDiv.fadeOut();
     $('.replyto').not(closestDiv.next('.replyto')).hide();
     //$('.reply').closest('div').not(closestDiv).show()
     closestDiv.next('.replyto').slideToggle(100);
  });
});

上面这个是切换"reply"形式的评论。它在第一级（评论）上工作，但不适用于子评论。

$(document).ready(function(){
  $(document).on('click' , '.clicktoviewreplies' , function(){
     var closestUl = $(this).closest('ul'); // also you can use $(this).parent()
     //closestUl.fadeOut();
     $('.replies').not(closestUl.next('.replies')).hide();
     //$('.clicktoviewreplies').closest('ul').not(closestUl).show()
     closestUl.next('.replies').slideToggle(100);
  });
});

上面这个是切换子评论或回复。类似于 "show replies" 和 "hide replies"。这就是整个 php 代码。它基于四个表格：registered_users、视频（虽然这里没有）、评论和子评论，如您所见。

<?php
while($commentslist = $showcomments->fetch()){
$iduser = $commentslist['idUser'];
$idcomment = $commentslist['id'];
$showuser = $pdo->prepare("SELECT * FROM registered_users WHERE id = ?");
$showuser->execute(array($iduser));

while($row6 = $showuser->fetch()){

<li>
<div>
    <b><?php echo $row6['username']; ?></b><br>             
    <?php echo $commentslist['comments']; ?>

<!--additional comment buttons or controllers-->
    <?php
    if($iduser == $row['id']){ ?> <button>Edit</button><?php }else{ ?> <button>Report</button><?php } ?> <button class="reply">Reply</button><?php if($iduser == $row['id']){ ?> <a onClick="return confirm('You sure you wanna delete that comment there')" href=""><button>Delete</button></a><?php }
    ?>
</div>

<div class="replyto">
    <!--THIS IS TO SUBMIT THE CHILD COMMENTS(SUBCOMMENTS)-->
    <form enctype="multipart/form-data" method="post" action="<?php echo "postsubcomment.php?id=$idcomment"; ?>">
        <textarea name="subcomment" cols="50" rows="4"></textarea>
        <input type="submit" name="reply" value="Submit">
    </form>
</div>
<span class="clicktoviewreplies"><b>View replies</b></span> <!--ATTENTION!HERE IT IS WHERE MY PROBLEM IS. I CLICK ON IT AND IT HIDES ALL "UL"(Unordered Lists) WITH CLASS ".REPLIES" AND NOT ONE BY ONE (SWITCHING) LIKE I'D LIKE. AND WHEN I CLICK ON IT AGAIN, IT DOESN'T RESHOW.-->
<!--SECOND LEVEL UNORDERED LIST-->
    <ul class="replies">
<!--Subcomments go/show here. This happens everytime the user replies to a main comment-->
    <?php
    $showsubcomments = $pdo->prepare("SELECT * FROM subcomments WHERE idComment = ?");
    $showsubcomments->execute(array($idcomment));
    while($subcommentslist = $showsubcomments->fetch()){
        $subcommenter = $subcommentslist['idComment'];
        $selectcomment = $pdo->prepare("SELECT * FROM comments WHERE id = ?");
        $selectcomment->execute(array($subcommenter));
        $row7 = $selectcomment->fetch();

        //This is to get the parent comment user
        $selectuser = $pdo->prepare("SELECT * FROM registered_users WHERE id = ?");
        $selectuser->execute(array($row7['idUser']));
        $row8 = $selectuser->fetch();

        $subcommentslist['idUser']; //The user that made the subcomment
        $selectuser2 = $pdo->prepare("SELECT * FROM registered_users WHERE id = ?");
        $selectuser2->execute(array($subcommentslist['idUser']));
        $row9 = $selectuser2->fetch();

?>
<!--SECOND LEVEL LIST ITEM: This is to show the subcomments-->
        <li>
        <div>   
            <?php echo "<b>".$row9['username']; ?>             
            <?php echo "<br>".$subcommentslist['subcomments']."<br>"; ?> 
            <!--additional subcomment buttons or controllers-->
            <?php
            if($row9['id'] == $row['id']){ ?> <button>Edit</button><?php }else{ ?> <button>Report</button><?php } ?> <button class="reply">Reply</button><?php if($row9['id'] == $row['id']){ ?> <a onClick="return confirm('You sure you wanna delete that comment there')" href=""><button>Delete</button></a><?php }
            ?>                                   
        </div>
        <div class="replyto" style="margin-left:5%; position:relative;">
            <!--THIS IS TO REPLY TO BOTH THE MAIN COMMENT AND SUBCOMMENTS BELOW IT-->
            <form enctype="multipart/form-data" method="post" action="<?php echo "postsubcomment.php?id=$idcomment"; ?>">
                <textarea name="subcomment" cols="50" rows="4"></textarea>
                <input type="submit" name="reply" value="Submit">
            </form>
        </div>
        </li>
<?php               
            }//THIRD (SUBCOMMENTS) WHILE CLOSED
        ?>
    </ul> <!--SECOND UNORDERED LIST CLOSED -->
</li>
<?php
} //SECOND WHILE CLOSED
} //FIRST WHILE CLOSED
?>

好吧，第一个实例（评论）"reply button "行为有效。为什么不是二审（回复子评论）？我想知道问题是第二个还是第三个 while 循环，或者它可能与 "ul" 和 "li" 安排有关。

Answer 1

嗯，这里的老大会为你解决这些问题，伙计。对于第二个问题（跨度："view replies"），将您的代码更改为：

$(document).ready(function(){
     $(".clicktoviewreplies").click(function(){
    //$(this).closest('ul').next('.replies').hide();
    //$('.replies').
    $('.replies').not($(this).next('.replies')).css("display", "none");
    $(this).next('.replies').slideToggle(100);
    }); 
});

并将文本更改为 "show/hide replies"。对于第一个问题（回复按钮和评论以及"subcomment"表单），删除"style"标签和所有css，属性"display: none"除外。请记住，jQuery 甚至 Javascript 代码可能会出现故障，因为您正在使用超出 class 本身所需的东西来识别代码中的元素。我不知道如何解释为什么会这样。所以不要使用：

<div class="replyto" style="margin-left:5%; position:relative;">

使用：

<div class="replyto">

而在 CSS 中，仅使用：

    .replyto
{
   display: none;
}

还有一个提示：为了拥有结构良好且 "understable" 的代码实现方式，您可以避免使用 "style" 标记并仅使用 CSS 在单独的样式表中组织文档。希望对你有所帮助，伙计。
