Question

当我尝试在Bootstrap中加载模态时，它会在我刷新页面时显示，但是当我点击按钮时它不会显示。我希望我的模式只有在用户点击按钮时才会弹出。

我的 html 文件设置如下：

<head>
    <meta charset="utf-8">
    <title>my title here</title>
    <link rel="stylesheet" type="text/css" href="/static/css/bootstrap.min.css">
    <script src="/static/js/jquery-3.2.1.min.js"></script>
    <script src="/static/js/popper.min.js"></script>
    <script src="/static/js/bootstrap.min.js"></script>
    <script src="/static/Highcharts-5.0.14/code/highcharts.js"></script>
    <script src="/static/Highcharts-5.0.14/code/modules/exporting.js"></script>
    <!-- Our Custom CSS -->
    <link rel="stylesheet" href="/static/css/style_charts_black.css">
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
</head>

我已从Bootstrap教程网站复制此代码：

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal" style="float:right; margin-right:100px">
Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="myModalLabel">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
      ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

<script>$('#myModal').modal('show')</script>

我在javascript控制台中没有得到任何jquery错误。我也尝试将上面的最后一行更改为 .modal（＆＃39; toggle＆＃39;），但它没有帮助。

Answer 1

您的代码很好，您需要将js文件包含在<body>标记中，而不是头部。

从他们的文件：

在关闭正文标记之前，在页面末尾添加我们的JavaScript插件，jQuery和Tether。

以下是我找到该信息的链接：

正文中包含的js文件的编解码器和您的代码正常工作：

Answer 2

您的代码工作正常，如果您只想在单击按钮时激活模态，则不需要脚本

$（＆＃39;＃myModal＆＃39;）模式。（＆＃39;秀＆＃39;）

只需删除html标记中的数据切换即可写

＆＃13;

$('#myModal').modal('show')
or
$('#myModal').modal('toggle')

＆＃13;

Bootstrap模式在点击时不显示
