单击链接，通过 JavaScript 打开 Bootstrap 4 Modal

Open Bootstrap 4 Modal via JavaScript by clicking a link

提问by Cray

I want to open a modal when I click on a link. Unfortunately I couldn't change the HTML of the link. I could only change the content of href.

我想在单击链接时打开一个模态。不幸的是，我无法更改链接的 HTML。我只能更改href.

Like this:

像这样：

<a href="#Modal">Open modal</a>

I could not add data-attributes or any other HTML.

我无法添加数据属性或任何其他 HTML。

In the docs I found a way to open the modal via JavaScript. I added this code to my site:

在文档中，我找到了一种通过 JavaScript 打开模态的方法。我将此代码添加到我的网站：

$('#Modal').modal();

It works but the modal opens immediately after the page loads. I need it to open after I click on the link.

它有效，但在页面加载后立即打开模态。我需要在单击链接后打开它。

Is there a way to do this?

有没有办法做到这一点？

Here's my modal:

这是我的模态：

<div class="modal" id="Modal" tabindex="-1" role="dialog" aria-labelledby="ModalTitle" aria-hidden="true">
    <div class="modal-dialog modal-dialog-centered" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <p class="h5 modal-title" id="ModalTitle">Modal Title</p>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
            </div>
            <div class="modal-body">
                Content
            </div>
        </div>
    </div>
</div>

Trigger click event on a[href$="#Modal"].

在 上触发点击事件a[href$="#Modal"]。

$('a[href$="#Modal"]').on( "click", function() {
   $('#Modal').modal('show');
});

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"></script>

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<!-- Trigger the modal with a button -->
<a href="#Modal" class="btn btn-info btn-lg">Open modal</a>
<!-- Modal -->
<div id="Modal" class="modal fade" 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>

need it to open after I click on the link.

单击链接后需要打开它。

So you'll need to check if the link is clicked.

所以你需要检查链接是否被点击。
