在页面加载上启动引导模式

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

为了避免引导被否决并失去它的功能，只需创建一个常规的启动按钮，为它提供一个Id，然后使用jquery“点击它”，如下所示: 启动按钮:

<button type="button" id="btnAnouncement" class="btn btn-primary" data-toggle="modal" data-target="#modalAnouncement">
  See what´s new!
</button>

jQuery触发器:

$(document).ready(function () {
  $('#btnAnouncement').click();
)}

希望能有所帮助。干杯!

其他回答

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">  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>  <div class="modal fade" id="myModal" role="dialog"> <div class="modal-dialog">  <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">×</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。

关于安德烈的伊里奇说你必须补充 js脚本在你称之为jquery的行之后:

<script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-2.1.1.js" type="text/javascript"></script>

<script type="text/javascript">
     $(window).load(function(){
         $('#myModal').modal('show');
      });
</script>

对我来说，这就是问题所在，希望能有所帮助

使用Bootstrap 3和jQuery(2.2和2.3)进行测试

$(window).on('load',function(){
  $('#myModal').modal('show');
});



<!-- 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"><i class="fa fa-exclamation-circle"></i>&nbsp; //Your modal Title</h4>
        </div>
        <div class="modal-body">
          //Your modal Content
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Fechar</button>
        </div>
      </div>

    </div>
</div>

也许已经晚了，但是，一旦我不能解决这个订单问题，模态没有显示;我使用jquery点击();

我试过了，效果不错:)

创建一个按钮，调用Modal show >样式的按钮作为display: none; 例子:

$( "#clickme" ).click(); <html> <head> <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> </head> <body> <input type="button" value="0" id="clickme" style="display:none;" data-toggle="modal" data-target="#exampleModal" />  <div id="exampleModal" class="modal" role="dialog"> <div class="modal-dialog">  <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">×</button> <h4 class="modal-title">Clicked Successfully</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> </body></html>

更新2020 -引导5

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 type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> Launch demo modal </button>  <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>
