Using sweetalert2 with bootstrap 4

I'm using sweetAlert2 and I'm trying to use bootstrap 4 to style buttons, setting the properties:

buttonsStyling: false,
confirmButtonClass: 'btn btn-primary btn-lg',
cancelButtonClass: 'btn btn-lg'

It works, however the showLoaderOnConfirm option is being shown in a very ugly style when I set those properties above.

You can check the examples below:

Steps to reproduce:

  • Input a valid email;
  • Press Submit;
  • See the loader (style) for the first (that's using bs4 and for the second, with the default style from swal2).

$(function() {
  $('#button').click(() => {
    swal({
      title: 'Submit email to run ajax request',
      input: 'email',
      showCancelButton: true,
      confirmButtonText: 'Submit',
      showLoaderOnConfirm: true,
      buttonsStyling: false,
      confirmButtonClass: 'btn btn-primary btn-lg',
      cancelButtonClass: 'btn btn-lg',
      preConfirm: function(email) {
        return new Promise(function(resolve, reject) {
          setTimeout(function() {
            if (email === 'taken@example.com') {
              reject('This email is already taken.')
            } else {
              resolve()
            }
          }, 2000)
        })
      },
      allowOutsideClick: false
    }).then(function(email) {
      swal({
        type: 'success',
        title: 'Ajax request finished!',
        html: 'Submitted email: ' + email
      })
    }).catch(swal.noop)
  });

  $('#button1').click(() => {
    swal({
      title: 'Submit email to run ajax request',
      input: 'email',
      showCancelButton: true,
      confirmButtonText: 'Submit',
      showLoaderOnConfirm: true,
      preConfirm: function(email) {
        return new Promise(function(resolve, reject) {
          setTimeout(function() {
            if (email === 'taken@example.com') {
              reject('This email is already taken.')
            } else {
              resolve()
            }
          }, 2000)
        })
      },
      allowOutsideClick: false
    }).then(function(email) {
      swal({
        type: 'success',
        title: 'Ajax request finished!',
        html: 'Submitted email: ' + email
      })
    }).catch(swal.noop)
  });
});

<body>
  <button id="button">Show (Bootstrap)</button>
  <hr />
  <button id="button1">Show (w/o bootstrap)</button>
</body>

</html>

The question is: How can I let the default style for the loader (using bs4)? Or maybe customize the style for the showLoaderOnConfirm option...

Solution

  • Live demo from the official website: https://sweetalert2.github.io/recipe-gallery/bootstrap.html

    Swal.fire({
  title: 'SweetAlert2 + Bootstrap 4',
  input: 'text',
  buttonsStyling: false,
  showCancelButton: true,
  customClass: {
    confirmButton: 'btn btn-primary btn-lg',
    cancelButton: 'btn btn-danger btn-lg',
    loader: 'custom-loader'
  },
  loaderHtml: '<div class="spinner-border text-primary"></div>',
  preConfirm: () => {
    Swal.showLoading()
    return new Promise((resolve) => {
      setTimeout(() => {
        resolve(true)
      }, 5000)
    })
  }
})
    .btn {
  margin: 0 6px;
}

.custom-loader {
  animation: none !important;
  border-width: 0 !important;
}
