Sweet Alert 刪除確認帶有 href

Question

我使用 PHP 和 Sweet alert 進行刪除確認。 問題是它在顯示甜蜜警報之前正在刪除。

這是我的 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>

這是我的甜蜜警報

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!");
  }
});

}

問題是，它沒有顯示甜蜜的警報，它只是直接轉到 URL。 我需要做一個表格並防止提交或類似的東西嗎？

問題是點擊錨元素有一個默認行為。 您可以使用event.preventDefault()來防止重定向並根據您的邏輯手動導航window.location.href='url'

<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!");
  }
});
}

您可以在 href 屬性中添加值javascript: :，如下所示

<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>

嘗試從鏈接中刪除 href 並僅在用戶單擊 SweetAlert 腳本中確認時才處理鏈接。

<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!");
  }
});
