JS | 如何使用 async await 迭代地运行函数

Question

I have a function

async function go(text)
{
    var response = await say(text);
    document.write(response + '<br>')
}

And a promise

function say(text)
{
    return new Promise((resolve, reject) => {
        if (enterPressed) resolve(text);
    });
}

I want to run the go function each time when the user pressed enter. For example, the script is:

go ("hello");
go ("goodbye")

I don't want these functions to be run immediately, I want first hello, then waiting for enter, then goodbye. Any methods?

Answer 1

how about:

async function foo() {
    while (true) {
        await go("hello");
        await go("goodbye");
    }
}
foo();

Did it. Thanks to Sandy Berkowitz.

async function go(text)
    {
        var response = await say(text);
        document.write(response + '<br>')
    }

    function say(text)
    {
        return new Promise((resolve, reject) => {
            document.addEventListener('keydown', (e) => 
            {
                if (e.keyCode == 13)
                {
                    resolve(text);
                }
            })
        });
    }

    async function foo()
    {
        await go('go');
        await go('Hello');
        await go('How are you?')
    }

    foo();
