我有一个引导模式对话框,我想首先显示,然后当用户在页面上单击时,它就消失了。我有以下几点:

$(function () {
   $('#modal').modal(toggle)
});

 <div class="modal" id='modal'>
     <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Error:</h3>
        </div>
        <div class="modal-body">
        <p>Please correct the following errors:</p>
        </div>
     </div>
 </div>

模态最初会显示,但在模态之外单击时不会关闭。此外,内容区域没有灰色。我怎么能得到模态显示最初,然后关闭后,用户点击区域外?我怎么能得到背景是灰色的演示?

用modal('toggle')代替modal(toggle)

$(function () {
   $('#modal').modal('toggle');
});

另一种方法是首先删除类modal-open,这样就关闭了模态。然后您删除类modal- background,它删除了模态的灰色封面。

可以使用以下代码:

$('body').removeClass('modal-open')
$('.modal-backdrop').remove()  

此外,你可以“点击”一个“x”,关闭对话框。 例如:

$ (" .ui-dialog-titlebar-close ") .click ();

<!DOCTYPE html> <html lang="en"> <head> <title>Bootstrap Example</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script> $(window).load(function(){ $('#myModal').modal('show'); }); $(function () { $('#modal').modal('toggle'); }); </script> </head> <body> <div class="container"> <h2>Modal Example</h2> <!-- 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> </body> </html>

你可以用;

$('#' + $('.modal.show').attr('id')).modal('hide');

在我的例子中,我使用了一个按钮来显示模式

<button type="button" class="btn btn-success" style="color:white"
    data-toggle="modal" data-target="#my-modal-to-show" >
    <i class="fas fa-plus"></i> Call MODAL
</button>

因此,在我的代码中,为了关闭模态(id = 'my-modal-to-show'),我调用了这个函数(在Angular typescript中):

closeById(modalId: string) {
  $(modalId).modal('toggle');
  $(modalId+ ' .close').click();
}

如果我调用$(modalId).modal('hide')它不工作,我不知道为什么

PS:在我的模态中,我用.close类编写了按钮元素

<button type="button" class="close" data-dismiss="modal" aria-label="Close"> 
    <span aria-hidden="true">&times;</span>
</button>
