删除前的 Sweet Alert 确认

Question

您好，我刚开始使用 sweet alert js 来让我的警报框更漂亮。我正在使用正常的 javascript 警报确认删除我 table 中的特定数据。但是，当我尝试运行在删除之前进行甜蜜的警报确认时，它会在不弹出确认的情况下删除文件。

下面是我的 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    swal("Deleted!", "Your imaginary file has been archived.", "success");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>

下面是我的 html 表格。

<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>

这里是 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

删除 <form> 并替换：

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

至：

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

从 "ajax_delete" 到

调用 onclick 函数

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

之后将您的删除代码放入 ajax 调用文件。

Answer 2

发生这种情况是因为您没有通过相应地使用 event.preventDefault() 或 return 和 false 或 true 来阻止浏览器的默认行为。

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

改变，

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

到，

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

为内联事件侦听器传递事件参数。

或者如果不需要 form 那么您可以删除 form 标签。

Answer 3

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

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");
  }
});
}

                Archive
        </button>
</form>

此删除确认码在 express js 中带有甜蜜提醒

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!");
           }
        });
}

<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/sweetalert/1.1.3/sweetalert.min.css">
<form name="myForm"  method="POST" action="/delete">
      <input type="hidden" value="<%= alldata[i]._id %>" name="std_id"> 
      <input type="submit" onclick="validateForm()" class="btn btn-danger btn-xs" value="DELETE">
</form>
