Question

我为我的机器人设置了清除功能，但是如果有人没有输入正确数量的消息进行清除，我希望它重新运行命令。唯一的问题是我似乎不知道该怎么办。这就是我所要做的：

const { Command } = require('discord.js-commando');

module.exports = class SayCommand extends Command {
    constructor(client) {
        super(client, {
            name: 'purge',
            group: 'group1',
            memberName: 'purge',
            description: 'Deletes messages from the current channel.',
            examples: ['purge'],
            args: [
                {
                    key: 'count',
                    prompt: 'How many messages do you want to delete?',
                    type: 'integer'
                }
            ]
        });
    }

    run(msg, { count }) {
        if(count < 1 || count > 30) {
            msg.channel.bulkDelete(count).then(() => {
            msg.say('Deleted ' + count + ' messages.').then(msg => msg.delete(3000));
            });
        } else {
        msg.say('You can delete 1 to 30 messages at a time.');
    }
    }
};

此后它将停止，您需要再次调用该命令。在用户输入正确的数字之前，是否有循环的方法？

谢谢！

您可以通过提供min和max值让Commando做到这一点：

args: [
            {
                key: 'count',
                prompt: 'How many messages do you want to delete?',
                type: 'integer',
                min: 1,
                max: 30,
                error: 'You can delete 1 to 30 messages at a time.'
            }
        ]
