单击按钮时模式不弹出

javascript html css modal-dialog bootstrap-modal

我正在做一个演练项目来学习引导程序，一切进展顺利，但是现在在项目的一部分中，我完美地遵循了创建注册模式，按钮不会导致模式弹出。

我已仔细检查所有引导链接是否按正确的顺序排列，三次检查拼写错误，一切似乎都很好，我看不出模式不起作用的原因。

您似乎忘记了一些标签和 ID。您应该使用：

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" />

<button class="btn btn-success btn-lg" data-toggle="modal" data-target="#signUpModal">Sign Up!</button>

<div class="modal fade" id="signUpModal" tabindex="-1" aria labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
        <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">&times;</span>
            </button>
        </div>
        <div class="modal-body">
            <p>Modal body text goes here.</p>
        </div>
        <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
        </div>
        </div>
    </div>
</div>

Answer 2

将此 :

<div class="modal" tabindex="-1" id="signUpModal">

更改为 :

<div class="modal fade" tabindex="-1" id="signUpModal" role="dialog" aria-labelledby="signUpModalLabel" aria-hidden="true">

我只是不明白为什么没有 .fade 类它就不起作用，因为文档说这是可能的 ...
