Question

我试图在有人单击X图标时关闭Bootstrap 4弹出窗口。

如果我删除代码“ data-backdrop =“ static”，则每当我在模式之外的任何地方单击时，它将关闭弹出窗口。但是，这是行不通的，因为每次有人尝试单击轮播的下一个图标时，它将自动关闭弹出窗口。我只希望当某人仅单击X图标时关闭弹出窗口。

Answer 1

您应该链接到 proper CSS和JavaScript文件；对于Bootstrap 4（撰写本文时，当前版本为4.3.1）：

关闭按钮的data-dismiss属性的值也应设置为modal：

<button type="button" class="close" data-dismiss="modal">&times;</button>

关闭按钮和转盘也应放置在.modal-content内-您可以使用自定义CSS来使模式透明。

工作示例

/* Automatically open the modal */
$('#myModal').modal('show');

/* Make the modal be transparent */
#myModal .modal-content {
  background-color: transparent;
  border: 0;
}

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" />

<div id="myModal" class="modal fade" role="dialog" data-backdrop="static">
  <div class="modal-dialog">
    <div class="modal-content">
      <!-- Button to close the modal -->
      <div><button type="button" class="close" data-dismiss="modal">&times;</button></div>

      <!-- Carousel -->
      <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
        <div class="carousel-inner">
          <div class="carousel-item active">
            <img class="d-block w-100" src="https://placeimg.com/550/250/nature" alt="First slide">
          </div>
          <div class="carousel-item">
            <img class="d-block w-100" src="https://placeimg.com/550/250/any" alt="Second slide">
          </div>
        </div>
        <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
          <span class="carousel-control-prev-icon" aria-hidden="true"></span>
          <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
          <span class="carousel-control-next-icon" aria-hidden="true"></span>
          <span class="sr-only">Next</span>
        </a>
      </div>
    </div>
  </div>

Answer 2

将此代码添加到脚本标签：

$('#myModal').find(".close").click(function() {
      $('#myModal').modal("hide");
});

因此您的代码应如下所示：

<script type="text/javascript">
    $(window).on('load',function(){
        $('#myModal').modal('show');
    });
    $('#myModal').find(".close").on("click", function() {
        $('#myModal').modal("hide");
    });
</script>

Answer 3

启动模态时，可以通过以下选项：

$data = $response->getBody()->getContents();
$base64 = 'data:image/png;base64,' . base64_encode($data);
echo '<img src="'.$base64.'">';

将无法通过单击背景和退出按钮来关闭模式。

或

{ keyboard: false, backdrop: 'static'}

在关闭图标上，您可以通过添加属性来关闭模型，例如

<div id="modal" class="modal hide fade in" data-keyboard="false" data-backdrop="static">

并在cancel（）方法上添加功能以关闭模型

data-dismiss="modal" or ng-click="cancel()"
