Question

我遇到了jQuery的问题。当我点击链接时，模态打开，我想将data-href的值传递给模态内的按钮。

单击按钮时没有任何反应。请你帮助我好吗？

链接

<a href="#" data-href="stackoverflow.com" data-toggle="modal" data-target="#openModal">Link</a>

模态

<div class="modal fade" id="openModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">         
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                        <button class="btn btn-danger btn-ok" href="">Go</button>
                    </div>
                </div>
            </div>
        </div>

JQuery的

    <script>
        $('#openModal').on('show.bs.modal', function(e) {
            $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
            $('.debug-url').html('Delete URL: <strong>' + $(this).find('.btn-ok').attr('href') + '</strong>');
        });
    </script>

的jQuery /波普/ JS

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> 
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.2/umd/popper.min.js"></script> 
<script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>

错误

Uncaught ReferenceError: $ is not defined

Answer 1

尝试使用shown代替show

$('#openModal').on('shown.bs.modal', function(e) {

Answer 2

试试这个：

$('#openModal').on('show.bs.modal', function(e) {
    var data_href = $(e.relatedTarget).attr('data-href');
    console.log('data_href: ' + data_href);

    $(this).find('.btn-ok').attr('href', data_href);
    $('.debug-url').html('Delete URL: <strong>' + $(this).find('.btn-ok').attr('href') + '</strong>');
});

你做的很好，但你的代码中有一点错误：

$(e.relatedTarget).data('href')

您尝试获取 href 属性，但您要查找的按钮上的属性为 data-href

Answer 3

我把jQuery文件放在头部而不是身体的底部，它可以工作。谢谢。

Answer 4

尝试此操作如果您发现此错误＆＃34;未捕获的ReferenceError：$未定义＆＃34;而不是取代＆＃34; $＆＃34; to＆＃34; jQuery＆＃34;。
