Question

嗨，我是新手使用甜蜜警报js让我的警报箱更加花哨。我正在使用正常的javascript警报确认删除我表中的特定数据。但是，当我尝试在删除之前运行甜蜜警报确认时，会删除该文件而不会弹出确认信息。

以下是我的JS中的代码。

<script>
    archiveFunction() {
        swal({
  title: "Are you sure?",
  text: "But you will still be able to retrieve this file.",
  type: "warning",
  showCancelButton: true,
  confirmButtonColor: "#DD6B55",
  confirmButtonText: "Yes, archive it!",
  cancelButtonText: "No, cancel please!",
  closeOnConfirm: false,
  closeOnCancel: false
},
function(isConfirm){
  if (isConfirm) {
    swal("Deleted!", "Your imaginary file has been archived.", "success");
  } else {
    swal("Cancelled", "Your imaginary file is safe :)", "error");
  }
});
    }
</script>

这是我下面的html表单。

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
        <input type="hidden" name="p_id" id="p_id" value="<?php echo $rows['p_id']; ?>">
        <button class="btn btn-danger" type="submit" name="archive" onclick="archiveFunction()">
            <i class="fa fa-archive"></i>
                Archive
        </button>
</form>

这是php中的代码。

<?php

include('../config.php');

if(isset($_POST['archive']))
{
$p_id = $_REQUEST['p_id'];
// sql to delete a record
$sqli = "UPDATE students SET archive = 2 WHERE p_id=$p_id";

if ($conn->query($sqli) === TRUE) {
    echo "swal('Archived!', 'Click ok to see!', 'success')";
} else {
    echo "Error Archiving record: " . $conn->error;
}

$conn->close(); 
}
?>

我想要发生的是在删除特定数据之前确认甜蜜警报确认。

Answer 1

正如其他提到的，您的按钮点击是将表单提交到指定的操作，您无法在警报中选择您的选项。因此，您应该使用event.preventDefault()阻止表单提交，并仅在用户按是时提交表单。

function archiveFunction() {
event.preventDefault(); // prevent form submit
var form = event.target.form; // storing the form
        swal({
  title: "Are you sure?",
  text: "But you will still be able to retrieve this file.",
  type: "warning",
  showCancelButton: true,
  confirmButtonColor: "#DD6B55",
  confirmButtonText: "Yes, archive it!",
  cancelButtonText: "No, cancel please!",
  closeOnConfirm: false,
  closeOnCancel: false
},
function(isConfirm){
  if (isConfirm) {
    form.submit();          // submitting the form when user press yes
  } else {
    swal("Cancelled", "Your imaginary file is safe :)", "error");
  }
});
}

<form action="abc" method="POST">
        <input type="hidden" name="p_id" id="p_id" value="<?php echo $rows['p_id']; ?>">
        <button class="btn btn-danger" name="archive" type="submit" onclick="archiveFunction()">
            <i class="fa fa-archive"></i>
                Archive
        </button>
</form>

Answer 2

删除<form>并替换：

<button class="btn btn-danger" type="submit">

为：

<button class="btn btn-danger ajax_delete" type="button">

从＆＃34; ajax_delete＆＃34;调用onclick函数通过

$(".ajax_delete").on("click", function (){ /*your sweet alert code and after ajax call function */});

之后将删除代码放到ajax调用文件中。

Answer 3

这种情况正在发生，因为您没有相应地return或false使用event.preventDefault()或true来阻止浏览器的默认行为。

function [...](e) {
    e.preventDefault();
    [...]
}

更改，

<button class="btn btn-danger" type="submit" name="archive" onclick="archiveFunction()">

要，

<button class="btn btn-danger" type="submit" name="archive" onclick="archiveFunction(event)">

传递内联事件侦听器的事件参数。

或者如果不需要form，则可以删除form代码。

此删除确认代码在快递js中带有甜蜜警报

我的代码：

function validateForm() {
      event.preventDefault(); // prevent form submit
      var form = document.forms["myForm"]; // storing the form
      swal({
             title: "Are you sure?",
             text: "Once deleted, you will not be able to recover this imaginary file!",
             icon: "warning",
             buttons: true,
             dangerMode: true,
           })
          .then((willDelete) => {
               if (willDelete) {
                     form.submit();
               } else {
                      swal("Your imaginary file is safe!");
           }
        });
}

      <input type="submit" onclick="validateForm()" class="btn btn-danger btn-xs" value="DELETE">
</form>
