我尝试做的是等待，直到正确的键被按下，让它继续
到目前为止我做的代码是这样的：

class exampleClass {
    async waitForKeyPress() {
        return new Promise((resolve) => {
        
            const listener = (e) => {
                document.body.removeEventListener("keydown", listener);
                if(e.key == "z") {resolve(); alert("e");}
                else {
                    this.waitForKeyPress();
                }
            }
            document.body.addEventListener("keydown", listener);
        });
    }

    async doStuff() {
        await this.waitForKeyPress();
        console.log("correct key pressed");
        //do stuff
    }
}

let exampleObject = new exampleClass();
exampleObject.doStuff();

这对我不起作用，因为如果我按下不同的键，它不会检测到z键因某种原因被按下。

async function waitForKeyPress() {
        return new Promise((resolve) => {
        
            const listener = (e) => {
                document.body.removeEventListener("keydown", listener);
                if(e.key == "z") resolve();
                else {
                    this.waitForKeyPress();
                }
            }
            document.body.addEventListener("keydown", listener);
        });
    }

    async function doStuff() {
        await this.waitForKeyPress();
        console.log("correct key pressed");
        //do stuff
    }

    doStuff();

唯一的区别是它不在课堂上。不过，我希望它是在一个类
