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?

美元(> '模式。4)模式(’hide’);

如果你在一个页面中使用多个模态弹出,使用上面的代码来隐藏模态的背景。

我们可以用以下方法关闭模式弹出窗口:

// We use data-dismiss property of modal-up in html to close the modal-up,such as

<div class='modal-footer'><button type='button' class="btn btn-default" data-dismiss='modal'>Close</button></div>

 // We can close the modal pop-up through java script, such as

 <div class='modal fade pageModal'  id='openModal' tabindex='-1' data-keyboard='false' data-backdrop='static'>

    $('#openModal').modal('hide'); //Using modal pop-up Id.
    $('.pageModal').modal('hide'); //Using class that is defined in modal html.

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>

这个非常好,它也适用于angular 2

$("#modal .close").click()

这段代码完美地为我关闭一个模态(我使用bootstrap 3.3)

$('#myModal').removeClass('in')
