Uncaught TypeError：无法读取未定义的SweetAlert和jquery的属性'then'

Question

大约在5天前工作，刚上了网站，它不再起作用，检查了Chrome控制台并发现此错误。

其余代码工作正常，一切都会按预期弹出。 .then刚刚崩溃。不确定是否由于更新。

谁能看到发生了什么事情吗？我是JS，Jquery等的新手。

未捕获的TypeError：无法读取未定义的属性'then'在Object.success（（index）：204）在c（jquery-3.4.1.min.js：2）在Object.fireWith [as resolveWith]（jquery-3.4.1.min.js：2）在l（jquery-3.4.1.min.js：2）在XMLHttpRequest。 （jquery-3.4.1.min.js：2）

这里是正在运行的代码

Answer 1

似乎您正在使用swal版本v1.0.0。

使用下面的语法代替swal({}).then()。

swal({
  title: "Looks like you're from " + countName + ". ",
  text: "Go to our International Store? ",
  imageUrl: 'https://www.countryflags.io/' + countCode + '/flat/64.png',
  imageWidth: 128,
  imageHeight: 128,
  showCancelButton: true,
  showConfirmButton: true,
  confirmButtonText: 'Yes take me there',
  cancelButtonText: 'Stay on U.S.A Site',
  imageAlt: 'Custom image',
  dangerMode: false,
}, function () {
  // Your code
});
