我已经解决这个bug一个小时了,但似乎找不到任何解决方案!我正在使用bootstrap,我有一个可解除的警报,但当我点击x来解除时,什么也没发生。
这是我的日记

<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>

这是我的页脚,我在其中包含了js文件。

<!-- 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>

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

<div class="alert alert-warning alert-dismissible" role="alert">

  <strong>Warning!</strong> Still on beta stage.

<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>
  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以消除警报时,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-src添加到代码中

<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

我现在使用Bootstrap v5.1,根据文档,模板为

<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

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-closedata-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>

我也一直在与之斗争。这不是最有效的方法,但这是我最终解决我正在工作的项目的方法。在我看来,当条件触发警报时,我使用了以下代码。

messages.error(request,'Insert your error message here')

然后在我想显示错误的页面模板中。其中“add_data”是显示错误的页面

<div class="alert alert-info">
    <a class="close" href="{% url 'add_data' %}" data-dismiss="alert"></a>
           {{ message }}
</div>

我的例子使用了href="#”,当你点击X时,它会转到页面的顶部。我只是改变了它,导航回清除警报消息的同一页面。希望这对大家有所帮助。

确保您成功地将CND添加到BootStrap Javascript中。您可能只在查看“入门”部分时包含了指向CSS链接的链接。
把这句话加到你的标题或结束语之前。

尝试使用此功能

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

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

});
并在span标记中声明类

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

应该在工作
