可解除警报

Question

我试图在单击 "x" 按钮时让警报消失，但似乎缺少某些东西使其无法正常工作，我不确定它是什么。

<div class="alert alert-success alert-dismissible">
<button type = "button" class="close" data-dismiss = "alert">x</button>
    You've done it!
</div>

Answer 1

要使 dismissible 起作用，您需要在文档中包含 jQuery 和 bootstrap.js。

 <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap 101 Template</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
</head>
<body>
<div class="alert alert-success alert-dismissible">
    <button type = "button" class="close" data-dismiss = "alert">x</button>
    You've done it!
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</body>
</html>
