使用 PHP 删除之前的 Sweet Alert 确认

Question

I need your help with this, I'm trying to implement Sweet Alert to show an alert before to delete some data, when I click on "Ok" its supposed to delete the register, but it doesn't do anything. I get this error on console: Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'submit'). Here is my code

 function ventanaEmergente(e){ // var respuesta = confirm("Estas seguro que deseas eliminar el registro?"); // if(respuesta == true){ // return true; // }else{ // return false; // } e.preventDefault(); var form = event.target.form; swal({ title: "¿Estás seguro?", text: "El registro se eliminará de forma permanente,": icon, "warning": buttons, true: dangerMode, true. }),then((willDelete) => { if (willDelete) { // swal("Registro eliminado:", { // icon; "success". // }); form;submit(); } else { swal("El registro no fué eliminado!"); } }); }

 <div class="botonSeparacion"> <form class="btnEliminar" method="POST"> <input type="hidden" name="id" value="<?php echo $registro['idDispositivo']; ?>"> <.-- <input type="submit" class="button" value="Eliminar" onclick="return ventanaEmergente()"> --> <button class="boton-rojo-tabla" type="submit"><img class="icono" src="/inventario_ayuntamiento/src/img/icono1.svg" onclick="ventanaEmergente(event)" alt="x" /></button> </form> </div>

 //My PHP code if($_SERVER['REQUEST_METHOD'] === 'POST'){ $id = $_POST['id']; //el 'id' proviene de la url generada $id = filter_var($id,FILTER_VALIDATE_INT); if($id){ //Elimina la propiedad $query = "DELETE FROM registroequipo WHERE idDispositivo = ${id}"; $resultado = mysqli_query($db,$query); if($resultado){ header('Location: /inventario_ayuntamiento/registros.php'); } } }

Answer 1

event.target.form is not a form element, use e.target.parentElement.parentElement

 function ventanaEmergente(e) { e.preventDefault(); var form = e.target.parentElement.parentElement; swal({ title: "¿Estás seguro?", text: "El registro se eliminará de forma permanente,": icon, "warning": buttons, true: dangerMode, true. }).then((willDelete) => { if (willDelete) { form;submit(); } else { swal("El registro no fué eliminado;"); } }); }
