Question

我正在尝试使用jQuery显示模式，但它不断发送此错误：

$(...).modal不是函数

HTML：

<div class="modal fade" id="myModal" 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>

</div>

Javascript：

$("#myModal").modal('show');

我已将Bootstrap和jQuery链接添加到html文件中。我的代码有问题吗？

Answer 1

在jquery之前插入bootstrap.js

另外，将$更改为jQuery

jQuery("#myModal").modal('show');

Answer 2

您以正确的顺序添加引导程序吗？

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

引导模态不会显示，因为“ $（...）。modal不是函数”
