警告框自动消失

Question

警告框自动消失

3

我正在使用Bootstrap，并希望实现以下功能：
有一种警报框，可以在短时间内自动消失。我想象中有一个特殊的东西，经常看到，但现在找不到了。我认为标准的bootstrap警报(http://getbootstrap.com/javascript/#alerts和http://getbootstrap.com/components/#alerts)不是正确的选择，因为我想要的只是“出现在某个东西的顶部”，而不是页面上的内容，如果你知道我的意思的话。

所以它应该只在进入页面时显示一个简短的“成功信息”，然后再次消失。或者我误解了Bootstrap警报，它正是我要寻找的东西吗？如果是，我该怎么使用它？我需要把那个“div”放在哪里？

我会使用toastr完成这样的事情 - exceptional exception

如果你想要一个警告框，可以考虑使用类似于Bootstrap模态框的东西。重点关注HTML和JS的使用。

这是一个简单的代码块，可以在点击时打开模态框，并在2秒后自动关闭模态框。

Html:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>


<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

Javascript：

$('#myModal').on('shown.bs.modal', function () {
  window.setTimeout(closeModal, 2000)
});

function closeModal(){
  $('#myModal').modal('hide');
}

是的，使用警报也可以实现这一点。只需为关闭添加超时并添加position: fixed样式，就可以使警报显示在内容前面。

下面的演示应该可以让您了解如何使用它。

相同的代码也在这个fiddle中。

$().alert();

setTimeout(function(){$('.alert').alert('close')}, 3000);

.alert {
    position: fixed;
    top: 0px;
}

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>
<div class="alert alert-danger alert-dismissible fade in" role="alert">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span>
    </button>
     <h4>Oh snap! You got an error!</h4>
