我正在尝试使用SweetAlert2创建一个逐步的表单,我需要能够在基于if语句的链接中添加额外的步骤。
例如,在我的第三个模态中,我可能会有一个广播问题,上面写着“你会加一个加号吗?”,如果用户选择“真”,我需要它弹出一个额外的阶段,询问'名字加一个',如果用户选择了假,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?
答案 0 :(得分:3)
一种方法是使用一个简单的Swal实例进行额外的选项步骤...并将值保存在全局声明的旁边变量中。
var plus1name="";
为了清楚起见,我不会重复所有代码,因为不变。这是一个要添加的新部分:
//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,因此数组中的顺序不是要求的顺序......
我在CodePen上进行了研究。
