javascript - 如何等待用户对 Meteor AutoForm 提交的响应？

Question

我正在使用 Meteor 和 Aldeed 的 Autoform。我想在提交之前检查用户是否确定。我已经尝试了很多方法，但是当我按下按钮时，表单仍然会提交。这是我现在所拥有的，它可以很好地生成一个模式(使用 SweetAlert)，即使提交发生在后台:

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"); });
        },

如何让表单等待用户确认或取消操作？

谢谢!

beginSubmit 在表单提交开始时调用。作为documentation状态，它可用于禁用/启用按钮或在提交较长请求时显示等待消息。如果您想根据用户的决定显示确认消息并提交表单，则需要使用 before Hook 。

例如:

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);
        }
      });
    }
  }
}
