Question

我正在使用PHP，并使用Sweet Alert进行删除确认。问题是它在显示甜蜜警报之前正在删除。

这是我的HTML（在其中使用PHP）。

<div class="delete"><a onclick="return confirmation()" href="'.URLROOT.'/dashboards/delete_note/'.htmlspecialchars($note->note_id).'/'.$data['table'] .'"><i class="far fa-trash-alt"></i></a></div>

这是我的甜蜜提醒

function confirmation() {
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) {
    swal("Poof! Your imaginary file has been deleted!", {
      icon: "success",
    });
  } else {
    swal("Your imaginary file is safe!");
  }
});

}

问题是，它没有显示警告，而是直接进入了URL。我需要填写表格并阻止提交吗？

Answer 1

问题是点击锚元素具有默认行为。您可以使用event.preventDefault()

使用window.location.href='url'来防止重定向并根据您的逻辑手动导航

<div class="delete"><a onclick="confirmation(event)" href="'.URLROOT.'/dashboards/delete_note/'.htmlspecialchars($note->note_id).'/'.$data['table'] .'"><i class="far fa-trash-alt"></i></a></div>

和js

function confirmation(ev) {
ev.preventDefault();
var urlToRedirect = ev.currentTarget.getAttribute('href'); //use currentTarget because the click may be on the nested i tag and not a tag causing the href to be empty
console.log(urlToRedirect); // verify if this is the right URL
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) => {
  // redirect with javascript here as per your logic after showing the alert using the urlToRedirect value
  if (willDelete) {
    swal("Poof! Your imaginary file has been deleted!", {
      icon: "success",
    });
  } else {
    swal("Your imaginary file is safe!");
  }
});
}

您可以像这样在href属性中添加值Viewencapsulation

javascript:

尝试从链接中删除href，并仅在用户单击SweetAlert脚本中的确认后处理链接。

<div class="delete"><a onclick="return confirmation()"><i class="far fa-trash-alt"></i></a></div>

在您的JavaScript中：

function confirmation() {
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) {

    // TODO: Handle your delete url by ajax
    // ...

    swal("Poof! Your imaginary file has been deleted!", {
      icon: "success",
    });
  } else {
    swal("Your imaginary file is safe!");
  }
});
