Im using PHP, and Sweet alert for a delete confirmation. Problem is that it is deleting before showing the sweet alert.
This is my HTML(which is using PHP in it).
<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>
This is my sweet alert
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!");
}
});
}
The problem is, its not showing the sweet alert, its just going straight to the URL. Do I need to do a form and prevent submits or something like that?
The problem is that click on anchor element has a default behavior. You could use event.preventDefault()
to prevent the redirection and navigate manually based on you logic with 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>
and in 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!");
}
});
}
You can add the value javascript:
in the href attribute, like this
<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>
Try removing the href from the link and only handle the link when user click confirmed in the SweetAlert script.
<div class="delete"><a onclick="return confirmation()"><i class="far fa-trash-alt"></i></a></div>
In your javascript:
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!");
}
});
