为什么单击关闭按钮后，可拒绝的警报不再出现？

Question

I was trying to use dismissible alert the same way as Bootstrap example shows:

<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> Better check yourself, you're not looking too good.
</div>

When the alert was shown, I clicked the close button. The alert was gone and everything was fine. But when I fired the same trigger trying to bring back the alert, it was not showing up again.

Is this the expected behaviour for dismissible alerts? How can I bring it back again? Thanks.

You can use jQuery's .show() and .hide() methods instead, "data-dismiss" removes the alert element from html.
