Bootstrap modal not showing up on click
提问by Joss
when I try to load a modal in Bootstrap, it shows up when I refresh the page but doesn't show up when I click on the button. I'd like my modal to pop up only when the user clicks on the button.
当我尝试在 Bootstrap 中加载模态时，它会在我刷新页面时显示，但在我单击按钮时不显示。我希望我的模态仅在用户单击按钮时弹出。
My htmlfile is set up as follows:
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>

I've copied this code from the Bootstrap tutorial website:
我已经从 Bootstrap 教程网站复制了这段代码：
<!-- 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">×</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>
I do not get any jquery errors in the javascript console. I've also tried to change the last line above to .modal('toggle')but it didn't help.
我在 javascript 控制台中没有收到任何 jquery 错误。我也尝试将上面的最后一行更改为.modal('toggle')但它没有帮助。

Your code is fine, you need to include the js files in the <body>tag, not the head.
你的代码很好，你需要在<body>标签中包含 js 文件，而不是头部。
From their documentation:
从他们的文档：
Add our JavaScript plugins, jQuery, and Tether near the end of your pages, right before the closing body tag.
将我们的 JavaScript 插件、jQuery 和 Tether 添加到页面末尾附近，就在结束正文标记之前。
Here is the link where I found that info:

And a codepen of the js files included in the body and your code working correctly:
以及包含在正文中的 js 文件的代码笔，并且您的代码可以正常工作：

Your code works fine, if you just want the modal to be activated when you click the button, you do not need the script
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
$('#myModal').modal('show')
$('#myModal').modal('show')
