I try to implement Sweet Alert to Node.js delete form

I'm trying to implement Sweet Alert to Node.js delete form, but unfortunately the alert doesn't work properly. It only pops up for a second and without clicking on delete button on the alert window, it deletes file from DB.
Here is my code:
<form action="/comicbooks/<%= comicbook._id %>/?_method=DELETE"
method="POST" class="deleteForm" onsubmit='swal({
title: "Are you sure?",
text: "Your will not be able to recover this imaginary file!",
type: "warning",
showCancelButton: true,
confirmButtonClass: "btn-danger",
confirmButtonText: "Yes, delete it!",
closeOnConfirm: false,
showLoaderOnConfirm: true,
},
function (isConfirm) {
location.reload();
});'>
<button class="btn btn-xs btn-danger">Delete</button>
</form>
Coul you please assist?
Many thanks in advance,
Szymon

You have two problems.
When the submit button is clicked, you want to display the alert, but you don't want the form to submit. You've done nothing to prevent the form from submitting.
When the alert has the OK button clicked, you want to submit the form, but you are reloading the current page instead.
So, sort out the submit button first.
Don't use the onsubmit attribute. It is more trouble than it is worth.
document.querySelector("form").addEventListener("submit", function (event) {
event.preventDefault(); // Stop normal form submitting
// Then include your code for showing the alert
});
Then make the alert do what you want when the OK button is selected.
function (isConfirm) {
document.querySelector("form").submit();
})

I finally found a bug in above code and now it is working perfectly in EJS file. There should be:
function archiveFunction(event) {
event.preventDefault(); // prevent form submit
var form = event.target.form; // storing the form
swal({
title: "Are you sure you want to delete the comicbook?",
text: "You will not be able to undo this action.",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Delete",
cancelButtonText: "Cancel",
closeOnConfirm: false,
closeOnCancel: false
},
function (isConfirm) {
if (isConfirm) {
form.submit(); // submitting the form when user press yes
} else {
swal("Cancelled", "Your comicbook has not been deleted.", "error");
}
});
}
Cheers,

Delete method with sweetalert in ruby on rails

Hi I am new in using sweet alert js to make my alert box more fancy. I am using the normal javascript alert confirmation to delete a specific data in my table. However when I try to run a sweet alert confirmation before deleting it deletes the file without the confirmation popping up.
Here is the code in my JS below.
$(".delete-alert").click(function(event) {
event.preventDefault();
swal({
title: 'Are you sure?',
text: "You won't be able to revert this!",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then(function () {
swal(
'Deleted!',
'Your file has been deleted.',
'success'
)
});
});
this is my ruby on rails with HTML which calls the above js when clicking on trash icon
<%= link_to raw('<i class="fa fa-trash delete-alert"></i>'), candidate_path(f.id),method: :delete %>

Here is the perfect example how you should use Sweet alert.
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
type: "warning",
showCancelButton: true,
confirmButtonClass: 'btn-danger',
confirmButtonText: 'Yes, delete it!',
cancelButtonText: "No, cancel plx!",
closeOnConfirm: false,
closeOnCancel: false
},
function (isConfirm) {
if (isConfirm) {
// Call your delete item function here.
swal("Deleted!", "Your imaginary file has been ted!", "success");
} else {
swal("Cancelled", "Your imaginary file is safe :)", "error");
}
});

Sweet Alert 2 confirmation before submit

I'm trying to make a confirmation pop up before submitting the form. But it's not working. I'm using Sweet Alert 2.
document.querySelector('#order').addEventListener('submit', function(e) {
var form = $(this).parents('form');
e.preventDefault();
swal({
title: "Are you sure?",
text: "Once a invoice is created, you will not be able to delete without the help of support",
type: "warning",
showCancelButton: true,
confirmButtonColor: '#DD6B55',
confirmButtonText: 'Yes, I am sure!',
cancelButtonText: "No, cancel it!",
}).then(function() {
swal({
title: 'Success!',
text: 'Invoice created! Go to the invoice tab to pay it.',
type: 'success'
}, function() {
form.submit();
});
},function(dismiss) {
if(dismiss == 'cancel') {
swal("Cancelled", "Invoice not created!", "error");
}
});
});
That's my Javascript code and my PHP code looks something like this
<?php
if(isset($_POST['k'])
{
header('Location: https://google.com');
}
?>
My HTML code is
<form method="POST">
<button type="submit" name="k"></button
</form>
It's not working why?
Update
$("#order").on('submit', function(e) {
var form = $(this);
e.preventDefault();
swal({
title: "Are you sure?",
text: "Once a invoice is created, you will not be able to delete without the help of support",
type: "warning",
showCancelButton: true,
confirmButtonColor: '#DD6B55',
confirmButtonText: 'Yes, I am sure!',
cancelButtonText: "No, cancel it!",
}).then(function() {
swal({
title: 'Success!',
text: 'Invoice created! Go to the invoice tab to pay it.',
type: 'success'
}, function() {
$(this).trigger('submit');
});
},function(dismiss) {
if(dismiss == 'cancel') {
swal("Cancelled", "Invoice not created!", "error");
}
});
});
Also I forgot to add that I parsed that code and on my actual code there is the ID on the form
By not working I mean the data isn't being posted. If it was working properly, it should be redirecting to google.com per the PHP code

I am no coder but I found that placing the submit under .then(function() { was a working solution for me. The code I used is lp.jQuery("div.main-form form").submit(); but your form name will be different. I hope it helps in some way.
$("#order").on('submit', function(e) {
var form = $(this);
e.preventDefault();
swal({
title: "Are you sure?",
text: "Once a invoice is created, you will not be able to delete without the help of support",
type: "warning",
showCancelButton: true,
confirmButtonColor: '#DD6B55',
confirmButtonText: 'Yes, I am sure!',
cancelButtonText: "No, cancel it!",
}).then(function() {
$(this).trigger('submit');
swal({
title: 'Success!',
text: 'Invoice created! Go to the invoice tab to pay it.',
type: 'success'
}, function() {
$(this).trigger('submit');
});
},function(dismiss) {
if(dismiss == 'cancel') {
swal("Cancelled", "Invoice not created!", "error");
}
});
});

First, you don't have the selector #order in this HTML.
Second, you'll want to prevent the default behavior of the form element, so do this:
$("form").on('submit', function(e) {
var form = $(this);
e.preventDefault();
//[...]
Then, where you want to finally submit, you can put this:
$(this).trigger('submit');

Page is not waiting for response from SweetAlert confirmation window

I am trying to upgrade my JavaScript confirm() action to use SweetAlert. Currently my code is something like this:
<a href="/delete.php?id=100" onClick="return confirm('Are you sure ?');" >Delete</a>
This waits for the user to confirm before navigating to the delete page. I would like to use this example from SweetAlert to ask the user to confirm before deleting:
swal({
title: "Are you sure?",
text: "You will not be able to recover this imaginary file!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
cancelButtonText: "No, cancel plx!",
closeOnConfirm: false,
closeOnCancel: false
},
function(isConfirm){
if (isConfirm) {
swal("Deleted!", "Your imaginary file has been deleted.", "success");
}
else {
swal("Cancelled", "Your imaginary file is safe :)", "error");
}
});
Everything I have tried has failed. When the first alert is displayed, the page has gone ahead and deleted the item and refreshed before the user has even clicked on the alert buttons. How do I make the page wait for the users input?
Any help would be greatly appreciated.

You cannot use this as a drop-in replacement for confirm. confirm blocks the single thread of execution until the dialog has been acknowledged, you cannot produce the same behavior with a JavaScript/DOM-based dialog.
You need to issue a request to /delete.php?id=100 in the success callback for your alert box.
Instead of...
swal("Deleted!", "Your imaginary file has been deleted.", "success");
You need
<a href="#">Delete<a>
...
$.post('/delete.php?id=100').then(function () {
swal("Deleted!", "Your imaginary file has been deleted.", "success");
});
You also must fix your delete.php to only accept POST requests. It's a huge problem to allow GET requests to delete resources. The first time Google or any other crawler finds your page, it will look at the href of every link in your document and follow each link, deleting all of your content. They will not be stopped by the confirm box, as they probably (with the exception of Google) won't be evaluating any JavaScript.

You can do it this way.
HTML:
<a href="/delete.php?id=100" class="confirmation" >Delete</a>
JS:
$('.confirmation').click(function (e) {
var href = $(this).attr('href');
swal({
title: "Are you sure?",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
cancelButtonText: "No, cancel plx!",
closeOnConfirm: true,
closeOnCancel: true
},
function (isConfirm) {
if (isConfirm) {
window.location.href = href;
}
});
return false;
});
Seems a hack but it's working for me.

$('.delete').click(function () {
var id = this.id;
swal({
title: "Are you sure?",
text: "Your will not be able to recover this post!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
closeOnConfirm: false
},
function(){
alert(id);
});
});
<a id="<?php echo $row->id_portfolio ?>" class=" delete">

Here's an example in an Angular directive (since SweetAlert is offered through an angular directive wrapper). This is one 'elegant' method for doing this in JavaScript. On a click event, there is an e.stopImmediatePropagation(), then if the user confirms, it evaluates the "ng-click" function. (Note scope.$eval is not a JavaScript eval()).
Markup:
<i class="fa fa-times" ng-click="removeSubstep(step, substep)" confirm-click="Are you sure you want to delete a widget?"></i>
Simple "confirm click" directive:
/**
* Confirm click, e.g. <a ng-click="someAction()" confirm-click="Are you sure you want to do some action?">
*/
angular.module('myApp.directives').directive('confirmClick', [
'SweetAlert',
function (SweetAlert) {
return {
priority: -1,
restrict: 'A',
link: function (scope, element, attrs) {
element.bind('click', function (e) {
e.stopImmediatePropagation();
e.preventDefault();
var message = attrs.confirmClick || 'Are you sure you want to continue?';
SweetAlert.swal({
title: message,
type: 'warning',
showCancelButton: true,
closeOnConfirm: true,
closeOnCancel: true
}, function (isConfirm) {
if (isConfirm) {
if(attrs.ngClick) {
scope.$eval(attrs.ngClick);
}
} else {
// Cancelled
}
});
});
}
}
}
]);

How to use sweet alert with Ember.js and Rails

I'm an Ember noob and have been having some trouble getting sweet alert to work with an ember/rails application. I believe I have a scope issue that I'm not quite sure how to handle..
Inside my controller I have a delete action with the following code inside:
swal({
title: "Are you sure?"
text: "You will not be able to recover this post!"
type: "warning"
showCancelButton: true
confirmButtonColor: "#DD6B55"
confirmButtonText: "Yes, delete it!"
closeOnConfirm: false
}, ->
#get('model').destroyRecord().then =>
#transitionToRoute 'posts'
swal("Deleted!", "Your post has been deleted.", "success")
)
I trace the error to the '#get('model').destroyRecord().then' and I am pretty sure it is because I am calling 'this.get' inside a function that is inside of a controller action. However, I don't know how to fix that... How do I reference the controller within a function? Any suggestions on how to correct this or a better way to achieve the same functionality?

I dont know about coffescript, but maybe you can try assigning the controller to a variable?
controller = this; // or # ?
swal({
title: "Are you sure?"
text: "You will not be able to recover this post!"
type: "warning"
showCancelButton: true
confirmButtonColor: "#DD6B55"
confirmButtonText: "Yes, delete it!"
closeOnConfirm: false
}, ->
controller.get('model').destroyRecord().then =>
controller.transitionToRoute 'posts'
swal("Deleted!", "Your post has been deleted.", "success")
)

use behavior: in data as :
<%= link_to "Delete", s, :method => :delete, data: { behavior: 'delete' } %>
$("[data-behavior='delete']").on("click", function(e){
e.preventDefault();
swal({
title: "Are you sure you want to delete " ,
text: "You will not be able to recover this data!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "Yes, delete it!",
closeOnConfirm: false
}, function(isConfirm) {
if (isConfirm)
{
// here you can use ajax to delete
swal("Deleted!", "Ok , rooms will be delete after submit.", "success");
}
else
{
return false;
}
});
});
