javascript - 如何使用jquery点击按钮隐藏数据库记录

Question

我有一个 View ，我正在其中以引导卡的形式获取数据库记录。在每张卡中，我都有与数据库列关联的复选框。 在选中复选框并单击保存按钮时，我想隐藏包含我输入该值的记录的卡

我怎样才能实现这个目标？我尝试使用卡的类名，但它隐藏了所有卡。

$('.insert').click(function() {
  var rId = $(this).data('rid');

  $.post("@Url.Action("
    SetCleaningStatus ", "
    HouseKeeping ")", {
      id: rId,
      InvChk: $('input[data-invchkid=' + rId + ']:checked').length,
      ClnChk: $('input[data-cleanid=' + rId + ']:checked').length,
      NewLin: $('input[data-nlid=' + rId + ']:checked').length,
      DpClean: $('input[data-dcid=' + rId + ']:checked').length
    });

  $('.Resbook').hide();
});

@model IEnumerable
<RoomTypeView>
  <div class="row">
    @foreach (var item in Model)

这个$('.Resbook').hide();隐藏了所有卡片。如何克服这个问题？我如何使用该 rId 来隐藏该特定卡片？

Answer 1

it is hiding all the cards

您需要确保仅隐藏相关卡。 .insert按钮位于 .card 内这样你就可以找到.card它在使用 .closest 内然后使用相对查找。

var card = $(this).closest(".card");
$('input[data-invchkid=' + rId + ']:checked', card)

或

card.find('input[data-invchkid=' + rId + ']:checked')

作为.card也是.Resbook ( <div class='card Resbook'> )您可以使用 .Resbook而不是.card ，例如:

var card = $(this).closest(".Resbook");
$(card).hide();

给予:

$('.insert').click(function() {
  var card = $(this).closest(".card");
  var rId = $(this).data('rid');

  $.post("@Url.Action("
    SetCleaningStatus ", "
    HouseKeeping ")", {
      id: rId,
      InvChk: $('input[data-invchkid=' + rId + ']:checked', card).length,
      ClnChk: $('input[data-cleanid=' + rId + ']:checked', card).length,
      NewLin: $('input[data-nlid=' + rId + ']:checked', card).length,
      DpClean: $('input[data-dcid=' + rId + ']:checked', card).length
    });

  $(card).hide();
});

显示 .closest() 的使用的示例片段使用OP结构:

$(".insert").click(function() {
  $(this).closest(".card").hide();
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
  <div class="col-3">
    <div class="card Resbook">
      <div class="card-body">
        Room 1
        <button type="button" class="btn btn-default insert" data-rid="@item.RoomId">Save</button>
      </div>
    </div>
  </div>
</div>
<div class="row">
  <div class="col-3">
    <div class="card Resbook">
      <div class="card-body">
        Room 2
        <button type="button" class="btn btn-default insert" data-rid="@item.RoomId">Save</button>
      </div>
    </div>
  </div>
</div>

如果按钮不在要使用的卡片的层次结构内，则可以通过data-rid=将它们链接在一起。值(value)观。

添加 .data-rid到.card让它们匹配:

<div class='card' data-rid='@item.RoomId'/>

然后将两者匹配

$("button").click(function() {
    var rid = $(this).data("rid");
    var card = $(".card[data-rid=" + rid + "]")

示例片段:

$(".external-insert").click(function() {
  var rid = $(this).data("rid")
  var card = $(".card[data-rid=" + rid + "]")
  card.hide();
  $(this).fadeOut(); // also hide the button
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
  <div class="col-3">
    <div class="card Resbook" data-rid="1">
      <div class="card-body">
        Room 1
      </div>
    </div>
  </div>
</div>
<div class="row">
  <div class="col-3">
    <div class="card Resbook" data-rid="2">
      <div class="card-body">
        Room 2
      </div>
    </div>
  </div>
</div>

<button type="button" class="btn btn-default insert external-insert" data-rid="1">Save 1</button>
<button type="button" class="btn btn-default insert external-insert" data-rid="2">Save 2</button>
