Internet Explorer 11上的SweetAlert2语法错误

Question

我正在使用SweetAlert2示例页面的确切代码:

swal({
  title: 'Are you sure?',
  text: "You won't be able to revert this!",
  type: 'warning',
  showCancelButton: true,
  confirmButtonColor: '#3085d6',
  cancelButtonColor: '#d33',
  confirmButtonText: 'Yes, delete it!'
}).then((result) => {
  if (result.value) {
    swal(
      'Deleted!',
      'Your file has been deleted.',
      'success'
    )
  }
})

适用于Firefox和Chrome,但是Internet Explorer显示SCRIPT1002: Syntax Error并且不运行脚本... IE将此部分标记为语法错误:

}).then((result) => {

谢谢你的帮助

(result) => {}是一个在IE中完全不支持的箭头功能.要解决这个问题,你必须使用传统的匿名函数:

swal({
  // options...
}).then(function(result) {
  if (result.value) {
    swal('Deleted!', 'Your file has been deleted.', 'success');
  }
});
