Javascript SweetAlert2检测单选按钮选择

我正在使用SweetAlert2JavaScript库来显示弹出窗口。SweetAlert2是SweetAlert的一个分支，不再维护。SweetAlert2允许我添加这样的单选按钮

// inputOptions can be an object or Promise
var inputOptions = new Promise(function(resolve) {
    resolve({
      '#ff0000': 'Red',
      '#00ff00': 'Green',
      '#0000ff': 'Blue'
    });
});

swal({
  title: 'Select color',
  input: 'radio',
  inputOptions: inputOptions,
  inputValidator: function(result) {
    return new Promise(function(resolve, reject) {
      if (result) {
        resolve();
      } else {
        reject('You need to select something!');
      }
    });
  }
}).then(function(result) {
  swal({
    type: 'success',
    html: 'You selected: ' + result
  });
})

<input id="swal2-radio-1" type="radio" name="swal2-radio" value="3">

SweetAlert2为无线电输入指定“swal2无线电”名称，如下所示

// inputOptions can be an object or Promise
var inputOptions = new Promise(function(resolve) {
    resolve({
      '#ff0000': 'Red',
      '#00ff00': 'Green',
      '#0000ff': 'Blue'
    });
});

swal({
  title: 'Select color',
  input: 'radio',
  inputOptions: inputOptions,
  inputValidator: function(result) {
    return new Promise(function(resolve, reject) {
      if (result) {
        resolve();
      } else {
        reject('You need to select something!');
      }
    });
  }
}).then(function(result) {
  swal({
    type: 'success',
    html: 'You selected: ' + result
  });
})

<input id="swal2-radio-1" type="radio" name="swal2-radio" value="3">

它应该打印到控制台，这样我就知道它工作了

以下是我目前掌握的代码：

是我做错了什么，还是因为SweetAlert2的工作方式，这不起作用？

您必须将事件逐个委托绑定到整个文档中

$(document).on("click",".swal2-container input[name='swal2-radio']", function() {
    var id = $('input[name=swal2-radio]:checked').val();
    console.log('id: ' + id);
});

非常感谢你，我自己永远也不会明白这一点
