基于 if 语句链接额外的 Sweet Alerts

Chaining extra Sweet Alerts based on if statement

我正在尝试使用 SweetAlert2 创建分步表单,我需要能够在基于 if 语句的链接中添加一个额外的步骤。

例如,在我的第三个模式中,我可能有一个单选问题,上面写着 'Will you be bringing a plus 1?',如果用户选择 'true',我需要它弹出一个额外的阶段,询问 [=20] =],如果用户选择 false 则继续。

swal.mixin({
        confirmButtonText: 'Next →',
        showCancelButton: true,
        progressSteps: ['1', '2', '3', '4']
      }).queue([
        {
            title: 'Which event?',
            text: 'Please start by selecting the event you would like to book in!',
            input: 'select',
            inputClass: 'swal-select-event',
            inputPlaceholder: 'Please Select',
            inputOptions: {
                '1' : 'Dance Event',
                '2' : 'Football Event'
            },
            inputValidator: (value) => {
                return new Promise((resolve) => {
                  if (value === '') {
                    resolve('You need to select an event!')
                  } else {
                    resolve()
                  }
                })
            }
        },
        {
            title: 'What Day?',
            text: 'Which day are they due to come in?',
            html:'<input id="swal-booking-date-select" type="date"/>',
            preConfirm: () => {
                return document.getElementById('swal-booking-date-select').value
            },
            inputValidator: (value) => {
                return new Promise((resolve) => {
                  if (value === '') {
                    resolve('You need to select a date!')
                  } else {
                    resolve()
                  }
                })
            }
        },
        {
            title: 'Plus one?',
            text: 'Will you be bringing a plus one with you?',
            input: 'radio',
            inputOptions: {
                    'yes' : 'Yes',
                    'no' : 'No'
                },
            inputValidator: (value) => {
                return new Promise((resolve) => {
                    if (value === null) {
                        resolve('I need to know if you will be bringing a plus 1!')
                    } else if(value === 'yes') {


                        //EXTRA STAGE GOES HERE TO GET PLUS ONE NAME


                    } else {
                        resolve()
                    }
                })
            }
        },
        {
            title: 'What else?',
            input: 'text',
            text: 'Any other information that needs noting for this booking?'
        }
      ]).then((result) => {
        if (result.value) {
            //Do something with all of the data here
        }
      })

有人知道这是否可行吗?

一种方法是为该额外的可选步骤使用一个简单的 Swal 实例...并将该值保存在全局声明的 aside 变量中。

var plus1name="";

为了清楚起见,我不会重复你所有的代码,因为没有改变。这是要添加的新部分:

//EXTRA STAGE GOES HERE TO GET PLUS ONE NAME
swal({
  title:"Plus one!",
  text:"What is his/her name?",
  input:"text"
}).then(function(value){
  plus1name = value;
  resolve();
});

然后在.then(result)部分:

//Do something with all of the data here

swalResults = result.value;
swalResults.push(plus1name.value)
console.log(swalResults);

所以你有一个包含所有答案的数组。额外的问题被推到了最后,所以数组中的顺序不是提问的顺序...

我在 CodePen 上处理过它。
