我根本不懂JavaScript。Bootstrap文档说到
通过JavaScript调用modal: $('#myModal').modal(options)
我不知道如何在页面加载上调用这个。使用Bootstrap页面上提供的代码,我可以成功地在元素单击上调用模态,但我希望它立即在页面加载上加载。

当前回答
您可以通过数据属性激活模态,而不需要编写任何JavaScript。
选项"show"设为true显示初始化时的模态:
<div class="modal fade" tabindex="-1" role="dialog" data-show="true"></div>
其他回答
只需将你想要在页面加载时调用的模态包装在文档头部的jQuery load事件中,它就会弹出,如下所示:
JS
<script type="text/javascript">
$(window).on('load', function() {
$('#myModal').modal('show');
});
</script>
HTML
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<a href="#" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
你仍然可以在你的页面中调用模态,通过这样的链接调用它:
<a class="btn" data-toggle="modal" href="#myModal">Launch Modal</a>
你不需要javascript来显示模态
最简单的方法是将"hide"替换为"in"
class="modal fade hide"
so
class="modal fade in"
你需要添加onclick = "$('.modal').hide()"按钮关闭;
PS:我认为最好的方法是添加jQuery脚本:
$('.modal').modal('show');
这里有一个解决方案[没有javascript初始化!]
我找不到一个例子,没有初始化你的模式与javascript, $('#myModal').modal('show'),所以这里有一个建议,你可以实现它没有javascript延迟页面加载。
用类和样式编辑你的modal容器div:
<div class="modal in" id="MyModal" tabindex="-1" role="dialog" style=" font - family:宋体;padding-right: 17 px;" >
Edit your body with class and style: <body class="modal-open" style="padding-right:17px;"> Add modal-backdrop div <div class="modal-backdrop in"></div> Add script $(document).ready(function() { $('body').css('padding-right', '0px'); $('body').removeClass('modal-open'); $('.modal-backdrop').remove(); $('#MyModal').modal('show'); }); What will happen is that the html for your modal will be loaded on page load without any javascript, (no delay). At this point you can't close the modal, so that is why we have the document.ready script, to load the modal properly when everything is loaded. We will actually remove the custom code and then initialize the modal, (again), with the .modal('show').
除了user2545728和Reft的答案,没有javascript,但与情态背景
添加3件事
一个在.modal类之前带有modal- background类的div Style ="display:block;"到.modal类 与.modal类一起淡出
例子
<div class="modal-backdrop in"></div>
<div class="modal fade in" tabindex="-1" role="dialog" aria-labelledby="channelModal" style="display:block;">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="channelModal">Welcome!</h4>
</div>
<div class="modal-body" style="height:350px;">

建立在优秀的回应从以前的答案,在Bootstrap 5没有jQuery,这已经工作;
document.querySelector('[data-target="#exampleModal"]').click();
完整的片段:
window.onload = () => { document.querySelector('[data-target="#exampleModal"]').click(); } <script src="https://stackpath.bootstrapcdn.com/bootstrap/5.0.0-alpha1/js/bootstrap.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js"></script> <link href="https://stackpath.bootstrapcdn.com/bootstrap/5.0.0-alpha1/css/bootstrap.min.css" rel="stylesheet" /> <div class="container py-3"> <!-- Button trigger modal --> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> Launch demo modal </button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog"> <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> </div>
