bootstrap通知弹框

提示框是一个小小的弹窗，在鼠标移动到元素上显示，鼠标移到元素外就消失。

如何创建提示框

通过向元素添加 data-toggle="tooltip" 来来创建提示框。

<a href="#" data-toggle="tooltip" title="提示内容">把鼠标移到到这里</a>

以下实例可以在文档的任何地方使用提示框：


<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script>
  <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
  <h3>提示框</h3><br>
  <a href="#" data-toggle="tooltip" title="提示内容">把鼠标移到到这里</a>
</div>
<script>
$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip();   
});
</script>
</body>
</html>

运行效果

指定提示框的位置

默认情况下提示框显示在元素上方。

可以使用 data-placement 属性来设定提示框显示的方向: top, bottom, left 或 right:


<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script>
  <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>
 
<div class="container">
  <h3>提示框</h3><br>
  <a href="#" data-toggle="tooltip" data-placement="top" title="提示内容">鼠标移动到我这</a>
  <a href="#" data-toggle="tooltip" data-placement="bottom" title="提示内容">鼠标移动到我这</a>
  <a href="#" data-toggle="tooltip" data-placement="left" title="提示内容">鼠标移动到我这</a>
  <a href="#" data-toggle="tooltip" data-placement="right" title="提示内容">鼠标移动到我这</a>
</div>
 
<script>
$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip();   
});
</script>
 
</body>
</html>

在按钮中使用:


<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script>
  <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>
 
<div class="container">
	<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">
	  Tooltip on top
	</button>
	<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">
	  Tooltip on right
	</button>
	<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">
	  Tooltip on bottom
	</button>
	<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">
	  Tooltip on left
	</button>
</div>
 
<script>
$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip();   
});
</script>
 
</body>
</html>

提示内容添加 HTML 标签，设置 data-html="true"，内容放在 title 标签里头:


<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
  Tooltip with HTML
</button>


<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
  <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script>
  <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>
 
<div class="container">
  <button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
  Tooltip with HTML
</button>
</div>
 
<script>
$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip();   
});
</script>
 
</body>
</html>

禁用按钮：


<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
