带有 href 的 Sweet Alert 删除确认

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（其中使用了 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，它没有显示甜蜜警报，它只是直接进入 URL。我是否需要做一个表格并防止提交或类似的东西？

Answer 1

问题是单击锚元素有默认行为。您可以使用 event.preventDefault() 来防止重定向并根据您的逻辑使用 window.location.href='url'

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>

在 js 中

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!");
  }
});
}

尝试从 link 中删除 href 并仅在用户在 SweetAlert 脚本中单击确认时处理 link。

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

在你的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!");
  }
});

你可以在 href 属性中添加值 javascript:，像这样

<a href = 'javascript:
    swal({
  title: "Delete selected item?",
  text: "Unrecoverable Data",
  icon: "warning",
  buttons: true,
  dangerMode: "true",
})
.then((willDelete) => {
  if (willDelete) {
   swal({ title: "Delete Data Successfully",
 icon: "success"}).then(okay => {
   if (okay) {
    window.location.href = "";
  }
});
    
  } else {
    swal({
    title: "Data Not Deleted",
     icon: "error",
    
    });
  }
});'
class = "btn btn-danger">Delete</a>
