引导模态对话框未显示(显示黑色背景)

我在html文件中有两个模式对话框(引起问题)。

模态对话框居于html文件序列的首位,单击按钮即可正确显示(反之亦然)。

这两种模式对话框都有唯一的ID,并且可以适当地调用,但是不会显示一个模式对话框(如果稍后单独调用)。

     <!-- Modal dialog xyz is the first in the sequence of html code -->
     <div class="modal fade" id="xyzModal" tabindex="-1" role="dialog" aria-labelledby="xyzModalTitle" aria-hidden="true">
        <div class="modal-dialog modal-dialog-centered" role="document">
          .....
        </div>
     </div>

     <!-- Modal dialog abc is the second M.D in the sequence of html code -->
     <div class="modal fade" id="abcModal" tabindex="-1" role="dialog" aria-labelledby="abcModalTitle" aria-hidden="true">
        <div class="modal-dialog modal-dialog-centered" role="document">
          .....
        </div>
     </div>

调用模态对话框时,我到底在哪里出错?

对于相应的按钮单击,我也正在使用隐藏/显示功能,但是不起作用。

     $("#xyzModal").modal('hide');
     $("#abcModal").modal('show');

如果您需要在打开新模态之前隐藏所有模态,那么最好的方法是:

$(".modal").modal('hide');
$("#abcModal").modal('show');

这可以确保在打开新的模式之前,将所有模式隐藏起来。

尝试以下代码。工作正常。使用下面的CDN和脚本。

<!DOCTYPE html>

    <title>Test Modal</title>

    <!-- Button trigger modal -->
    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#xyzModal">

    <!-- Button trigger modal -->
    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#abcModal">
        Launch abcModal modal

    <!-- Modal dialog xyz is the first in the sequence of html code -->
    <div class="modal fade" id="xyzModal" tabindex="-1" role="dialog" aria-labelledby="xyzModalTitle" aria-hidden="true">
