Javascript 意外标记“case”（switch语句）

我正在制作一个热点，它使用Ajax将用户登录到路由器

如果连接到网络时出现问题，它应该会弹出一个警报，说明存在问题，请联系接待处

我使用的是switch语句，它根据客户端语言/所选语言显示消息

我在代码的其余部分有一堆switch语句，它们都工作得很好，但是这里我得到一个错误，那就是

Uncough SyntaxError:意外标记“case”

任何帮助和解释为什么这个错误只发生在这里将是非常感谢的。多谢各位

function Ajax1 (method, url){
    return new Promise (function (resolve,  reject){
        let xhr = new XMLHttpRequest();
        xhr.open('POST', 'http://10.5.50.1/login', true);
        xhr.onload = function(){
            if(this.status >= 200 && this.status < 300){
                resolve(xhr.response);
            }else{

switch是一个语句，而不是一个表达式。它不能用于对象文字或函数的参数。你需要把它从拒绝论点中去掉

            }else{
                switch (global){
                    case "sl":
                        alert("Prišlo je do napake. Prosim obrnite se na recepcijo.");
                        break;
                    case "en":
                        alert("There seems to be an issues. Please contact the reception.");
                        break;
                    case "de":
                        alert("There seems to be an issues. Please contact the reception.");
                        break;
                    case "it":
                        alert("There seems to be an issues. Please contact the reception.");
                        break;
                    case "hr":
                        alert("There seems to be an issues. Please contact the reception.");
                        break;
                    case "ru":
                        alert("There seems to be an issues. Please contact the reception.");
                        break;
                    default:
                        alert("There seems to be an issues. Please contact the reception.");
                }
                reject();
            }

错误发生在哪一行？通常这意味着前一行有错误。不能将switch语句放在对象文本中。为什么要尝试在参数中使用switch语句来拒绝？
