[英]bootstrap modal dialog not showing (black background showing)
我在 html 文件中有两个模式对话框(导致问题)。
哪个模态对话框首先放置在 html 文件的序列中,在按钮单击时正确显示(反之亦然)。
两个模态对话框都有唯一的 id 并且被适当地调用,但是一个模态对话框没有显示(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>
我在调用模态对话框时到底哪里出错了。
对于相应的按钮点击,我也在使用隐藏/显示功能,但不起作用。
$("#xyzModal").modal('hide');
$("#abcModal").modal('show');
如果您需要在打开新模式之前隐藏所有模式,那么最好的做法是:
$(".modal").modal('hide');
$("#abcModal").modal('show');
这可确保在您打开新模式之前隐藏所有模式。
试试下面的代码。 它正在工作。 使用下面的 CDN 和脚本。
