如何提示用户再次尝试输入

Question

这是我的代码。我想知道如果用户不能满足长度小于200个字符的要求，是否有一种方法可以提示用户再次尝试输入标题。谢谢你的帮助！

message.author.send(
'Lets get to work!nPlease enter the title of your event. (Must be shorter than 200 characters)'
);
message.channel
.awaitMessages(
(response) =>
response.author.id === message.author.id && response.content.length < 200,
{
max: 1,
time: 10000,
errors: ['time'],
}
)
.then((collected) => {
message.author.send(`I collected the message : ${collected.first().content}`);
let title = collected.first().content;
})
.catch(() => {
message.author.send('No message collected after 10 seconds.');
});

你可以把它放在一个函数中，然后一遍又一遍地重复这个函数。

message.author.send(
'Lets get to work!nPlease enter the title of your event. (Must be shorter than 200 characters)'
);
const collecter = () => {
message.channel
.awaitMessages(
(response) => response.author.id === message.author.id, // remove requirement from function
{
max: 1,
time: 10000,
errors: ['time'],
}
)
.then((collected) => {
if (collected.first().content.length < 200) {
// add it in the callback
message.channel.send('bla bla bla went wrong! Please try again');
collector(); // repeat the function
}
message.author.send(
`I collected the message : ${collected.first().content}`
);
let title = collected.first().content;
})
.catch(() => {
message.author.send('No message collected after 10 seconds.');
});
};
collector();
