Bootstrap 可关闭警报不起作用

Question

我已经解决了这个错误一个小时，但似乎找不到任何解决方案！我正在使用引导程序并且我有一个可关闭的警报但是当我点击 x 关闭时没有任何反应。

这是我的 div

<div class="alert alert-warning alert-dismissible" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <strong>Warning!</strong> Still on beta stage.
</div>

这是我包含 js 文件的页脚

<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

Answer 1

对于 Bootstrap v.5.1 只需在 alert-dismissible 之后添加 fade show 并在类之后添加 btn-close 和 data-bs-dismiss

    <div class="alert alert-warning alert-dismissible fade show" role="alert">
  <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <strong>Warning!</strong> Still on beta stage.
</div>

Answer 2

我现在使用的是 Bootstrap v5.1，根据文档，模板是

<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
</div>

参考：https://getbootstrap.com/docs/5.1/components/alerts/#dismissing

Answer 3

如果您使用的是 Bootstrap 5.0，bootstrap.js 代码中的 data-dismiss 选择器似乎已更改为 data-bs-dismiss。 所以我只需要将 data-dismiss="modal" 更改为 data-bs-dismiss="modal" 就可以了。

Answer 4

确保您已成功将 CND 添加到 BootStrap Javascript。查看“入门”部分时，您可能只包含了指向 CSS 链接的链接。

将此添加到您的标题或在您的结束正文之前。

Answer 5

<div class="alert alert-success alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="close" data-dismiss="alert" aria-label="Close" style="outline: none;">
    <span aria-hidden="true">&times;</span>
  </button>
</div>
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-ho+j7jyWK8fNQe+A12Hb8AhRq26LrZ/JpcUGGOn+Y7RsweNrtN/tE3MoK7ZeZDyx" crossorigin="anonymous"></script>
<script>
  document.addEventListener('DOMContentLoaded', () => {
    $('.alert').alert()
  })
</script>

要解决您的问题，请使用上面的代码

<script>
  document.addEventListener('DOMContentLoaded', () => {
    $('.alert').alert()
  })
</script>

当您单击X 关闭警报时，它会运行一个名为 alert() 的 js 函数，要使用此函数，您需要将下面给出的 script-srcs 添加到您的代码中

<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-ho+j7jyWK8fNQe+A12Hb8AhRq26LrZ/JpcUGGOn+Y7RsweNrtN/tE3MoK7ZeZDyx" crossorigin="anonymous"></script>

Answer 6

试试这个功能

$('.close').click(function(){
     $(".test").css("display", "none");

或

  $('.test').hide();

});

并在 span 标签中声明一个类

<strong class="test">Warning!</strong> Still on beta stage.

应该可以工作

Answer 7

<div class="alert alert-warning alert-dismissible" role="alert">
  <span type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></span>
  <strong>Warning!</strong> Still on beta stage.
</div>
