javascript - 如何使用 Sweet Alert 进行确认？

Question

在此代码中，即使我单击“否”，也会提交表单

document.querySelector('#from1').onsubmit = function(){

 swal({
    title: "Are you sure?",
    text: "You will not be able to recover this imaginary file!",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: '#DD6B55',
    confirmButtonText: 'Yes, I am sure!',
    cancelButtonText: "No, cancel it!",
    closeOnConfirm: false,
    closeOnCancel: false
 },
 function(isConfirm){

   if (isConfirm){
     swal("Shortlisted!", "Candidates are successfully shortlisted!", "success");

    } else {
      swal("Cancelled", "Your imaginary file is safe :)", "error");
    }
 });
};

您需要防止提交时的默认表单行为。之后，如果选择“确定”按钮，您将需要以编程方式提交表单。

它可能是这样的:

document.querySelector('#from1').addEventListener('submit', function(e) {
  var form = this;

  e.preventDefault(); // <--- prevent form from submitting

  swal({
      title: "Are you sure?",
      text: "You will not be able to recover this imaginary file!",
      icon: "warning",
      buttons: [
        'No, cancel it!',
        'Yes, I am sure!'
      ],
      dangerMode: true,
    }).then(function(isConfirm) {
      if (isConfirm) {
        swal({
          title: 'Shortlisted!',
          text: 'Candidates are successfully shortlisted!',
          icon: 'success'
        }).then(function() {
          form.submit(); // <--- submit form programmatically
        });
      } else {
        swal("Cancelled", "Your imaginary file is safe :)", "error");
      }
    })
});

<子>UPD。上面的示例使用 sweetalert v2.x Promise API。
