警報框自動消失

Question

我正在使用Bootstrap並希望實現以下功能：
有一種警報盒，它會在很短的一段時間后自動消失。 我的想象力中有一些特別的東西，我經常看到，但此刻找不到。 我認為標准的引導警報（ http://getbootstrap.com/javascript/#alerts和http://getbootstrap.com/components/#alerts ）不是正確的，是嗎？ 因為我想要一些東西只是“出現在某個東西之上”，所以不是作為頁面的內容，如果你知道我的意思。

所以它應該只是在進入頁面時顯示一個簡短的“成功信息”，然后它應該再次消失。 或者我錯過了解錯Bootstrap警報錯誤，這正是我正在尋找的？ 如果是，我該如何使用它？ 我在哪里放“div”？

Answer 1

是的，警報也可以。 只需為結束添加超時並添加position: fixed樣式以在內容前面顯示警報。

以下演示應該讓您了解如何使用它。

同樣的代碼也在這個小提琴 。

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

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

Answer 2

如果你想要一個警告框，你可以考慮像bootstrap模式。 專注於html和js的使用

http://getbootstrap.com/javascript/#modals-examples

http://getbootstrap.com/javascript/#modals-usage

這是一個簡單的代碼塊，可以在點擊時打開模態，並在2秒后自動關閉模態。

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>

使用Javascript：

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

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