模态窗体不显示

Question

我有一个 .jsp 文件，其中有一个 header，其中包含一个 ID 为“modalFormButton”的按钮，按下该按钮时必须显示模态表单。模态形式的代码在另一个 .jsp 文件中，所以我动态添加它。我已经检查过它是否成功调用了包含上述内容的文件，但它不显示表单。我也尝试将表单代码放在同一个文件中。jsp 我从中调用它，但它也不起作用。

PS：模态表单包含在 ID 为“agregarClienteModal”的 div 中。另外，我正在使用 Bootstrap.

.jsp 主文件：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        
        <!-- Bootstrap CSS -->
        <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-eOJMYsd53ii+scO/bJGFsiCZc+5NDVN2yr8+0RDqr0Ql0h+rP48ckxlpbzKgwra6" crossorigin="anonymous">
        <title>JSP Page</title>
    </head>
    <body>
        <header class = "py-2 bg-info text-white">
            <div>
                <h1>
                    Clients
                </h1>
                <button type = "button" id = "modalFormButton" class="btn btn-primary btn-block data-toggle="modal" data-target="#agregarClienteModal">
                     Agregar Cliente
                </button>
            </div>
             <jsp:include page="addClientModalForm.jsp"/>
        </header>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/js/bootstrap.bundle.min.js" integrity="sha384-JEW9xMcG8R+pH31jmWH6WWP0WintQrMb4s7ZOdauHnUtxwoG2vI5DkLtS3qm9Ekf" crossorigin="anonymous"></script>
    </body>
</html>

模态形式代码：

<div class="modal fade" id="agregarClienteModal">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">
            <div class="modal-header bg-info text-white">
                <h5 class="modal-title">Agregar Cliente</h5> 
                <button class="close" data-dismiss="modal">
                    <span>&times;</span>
                </button>
            </div>
            
            <form action="${pageContext.request.contextPath}/servlet?accion=insertar"
                  method="POST" class="was-validated">
                
                <div class="modal-body">
                    <div class="form-group">
                        <label for="nombre">Nombre</label>
                        <input type="text" class="form-control" name="nombre" required>
                    </div>
                    <div class="form-group">
                        <label for="apellido">Apellido</label>
                        <input type="text" class="form-control" name="apellido" required>
                    </div>
                    <div class="form-group">
                        <label for="email">Email</label>
                        <input type="email" class="form-control" name="email" required>
                    </div>
                    <div class="form-group">
                        <label for="telefono">Teléfono</label>
                        <input type="tel" class="form-control" name="telefono" required>
                    </div>
                    <div class="form-group">
                        <label for="saldo">Saldo</label>
                        <input type="number" class="form-control" name="saldo" required step="any">
                    </div>
                </div>
                <div class="modal-footer">
                    <button class="btn btn-primary" type="submit">Guardar</button>
                </div>    
            </form>
        </div>
    </div>
</div>

Answer 1

data- 属性在 Bootstrap 中更改为 data-bs- 5...

<div>
   <h1> Clients </h1>
   <button type="button" id="modalFormButton" class="btn btn-primary btn-block" data-bs-toggle="modal" data-bs-target="#agregarClienteModal"> Agregar Cliente </button>
</div>
