我正在使用bootstrap 4模态。但它不能正常工作,当点击按钮时,模态不会出现。它只是一个灰色的背景,然后这个背景消失了。你知道问题出在哪里吗?
//关闭标记<body>
之前是导入
<script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.3/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
<link href="css/app.css" rel="stylesheet" type="text/css">
<script type="text/javascript" src="js/app.js"></script>
打开模态的输入位于表单内:
// html
<input type="submit" class="btn" data-toggle="modal" data-target="#myModal" value="Send"/>
</form>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">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>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
// js
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()
})

如果您使用输入类型=&#34;提交&#34;显示模态您的网站将在模态显示之前重新加载。尝试更改输入类型=&#34;提交&#34;输入type =&#34; button&#34;兄弟。
