How to wait for user response on Meteor AutoForm submission?

Question

I am using Meteor and Aldeed's Autoform. I want to check that the user is certain before submission takes place. I have tried many things but when I press the button, the form submits anyway. Here's what I have now, which produces a modal nicely (with SweetAlert) even though submission occurs in the background anyway:

AutoForm.hooks({
    createEventForm: {
        before: function() {
            this.event.preventDefault();
        },
        beginSubmit: function() {
            this.event.preventDefault();
            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!",
                closeOnConfirm: true },
                function(){
                swal("Deleted!", "Your imaginary file has been deleted.", "success"); });
        },

How can I make the form wait for the user to confirm or cancel the operation?

Thanks!

Answer 1

The beginSubmit is called at the beginning of the form submission. As the documentation states, it can be used to disable/enable buttons or showing a wait message when submitting longer requests. If you want to display a confirmation message and submit the form depending on the user's decision, you need to use the before hook.

For example:

AutoForm.hooks({
  createEventForm: hooksObject
});

var hooksObject = {
  before: {
    insert: function(doc) {
      var self = this;
      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!",
        closeOnConfirm: true
      }, function(isConfirm) {
        if (isConfirm) {
          /* Submit form: */
          self.result(doc);
          swal("Deleted!", "Your imaginary file has been deleted.", "success");
        } else {
          /* Async cancel form submission: */
          self.result(false);
        }
      });
    }
  }
}
