無法在 if 函數中使用 await

Question

我正在編寫一個應用程序命令，以便我的服務器成員可以申請員工。 我正在嘗試使用我的朋友處理程序，它提供了一個prompt功能。 我使用 await 來確保之后的問題不會在解決之前的問題之前執行，但是我無法在我擁有的 if 語句中使用 await。

我收到一個錯誤Unexpected error: unexpected token call這顯然意味着有些東西是額外的或不應該在那里。

在這種情況下，我將如何使用 await 來確保下一個提示不會在它應該執行之前執行？ 或者，如果這是不可能的，任何建議都會很棒。

您的問題從問題 4 開始。您試圖在不等待返回的情況下運行代碼。

if (positionInput.content.toLowerCase() === 'community agent') {
    // Won't wait
    call.prompt(question5CommunityString, {
        time: 50000,
        channel: usersDMs
    }).then(question5CMsg => {
        question5Answer = question5CMsg.content; // Won't run we likely already left the scope without waiting for the return
    });

    // Won't wait
    call.prompt(question6CommunityString, {
        time: 50000,
        channel: usersDMs
    }).then(question6CMsg => {
        question5Answer = question6CMsg.content; // Won't run we likely already left the scope without waiting for the return
    });
}

// This will likely run before the code above completes and will send the moderators.
if (positionInput.content.toLowerCase() === 'moderator') {
    positionChoice = positionInput.content;
    call.messge.author.send('moderators')
}

嘗試將代碼拉到問題 4 中的 then 語句之外，否則您需要一個接一個地鏈接承諾。

// Put this somewhere safe up top
let question4Response;

// Your new code:

    then(positionInput => {
        question4Response = positionInput;
    });
}

if (question4Response.content.toLowerCase() === 'community agent') {
    await call.prompt(question5CommunityString, {
        time: 50000,
        channel: usersDMs
    }).then(question5CMsg => {
        question5Answer = question5CMsg.content;
    });

    await call.prompt(question6CommunityString, {
        time: 50000,
        channel: usersDMs
    }).then(question6CMsg => {
        question6Answer = question6CMsg.content;
    })
}
else if (question4Response.content.toLowerCase() === 'moderator') {
    positionChoice = question4Response.content;

    call.messge.author.send('moderators')
}
