如何使用轮播关闭 X 上的 Bootstrap 4 弹出窗口

Question

当有人单击 X 图标时，我试图关闭 Bootstrap 4 弹出窗口。

如果我删除代码 'data-backdrop="static"，每当我单击模式外的任何位置时，它都会关闭弹出窗口。但是，这不会起作用，因为每次有人尝试单击轮播的下一个图标时，它都会自动关闭弹出窗口。我只想在有人只点击 X 图标时关闭弹出窗口。

Answer 1

您应该链接到 正确 CSS 和 JavaScript 文件；对于 Bootstrap 4（目前的版本是 4.3.1）：

• CSS：https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css

• JavaScript：https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js

关闭按钮的data-dismiss属性的值也应该设置为modal：

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

关闭按钮和轮播也应该放在.modal-content 中——您可以使用自定义 CSS 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>
</div>

Answer 2

将此代码添加到您的脚本标签中：

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

所以你的代码应该是这样的：

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

Answer 3

当你启动你的模式时，你可以传递下面给出的选项：

{ keyboard: false, backdrop: 'static'}

这将禁用通过单击背景和退出按钮来关闭模式。

或

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

在关闭图标上，您可以通过添加属性来关闭模型

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

并在 cancel() 方法上添加功能以关闭模型

`$('#myModal').modal("hide");
