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

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');

只需添加下面的-

class="modal show"

工作示例,

<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <div class="container"> <!-- Trigger the modal with a button --> <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button> <!-- Modal --> <div class="modal show" id="myModal" role="dialog"> <div class="modal-dialog"> <!-- Modal content--> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">&times;</button> <h4 class="modal-title">Modal Header</h4> </div> <div class="modal-body"> <p>Some text in the modal.</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> </div>

您可以尝试这个可运行的代码-

$(window).load(function() { $('#myModal').modal('show'); }); <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <div class="container"> <!-- Trigger the modal with a button --> <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button> <!-- Modal --> <div class="modal fade" id="myModal" role="dialog"> <div class="modal-dialog"> <!-- Modal content--> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">&times;</button> <h4 class="modal-title">Modal Header</h4> </div> <div class="modal-body"> <p>Some text in the modal.</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> </div>

我想你已经有了完整的答案。

你可能想要保持jquery.js延迟,以更快的页面加载。但是,如果jquery.js被延迟到$(window)。负载可能不工作。那么你可以试试

setTimeout(function(){$('#myModal').modal('show');},3000);

它会在页面完全加载后弹出你的模态(包括jquery)

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').
