Question

I'm trying to create a discord.js announcement bot ex. When I write ?Ann Hello Guys the bot delete my message and send Hello Guys but now if I write ?Ann Hello Guys the bot delete my message and send ?Ann Hello Guys the code is this
const client = new Discord.Client();
client.login('--------------');
const PREFIX = '?';
client.once('ready', () => {
console.log('Questo bot e online!');
});
client.on('message', message=>{
let args = message.content.slice(PREFIX.length).split(' ');
switch(args[0]){
case 'ann':
const embed = new Discord.MessageEmbed()
.addField('test', message.content );
message.channel.send(embed);
break;
}
})

Answer 1

Made a pen for this:
https://codepen.io/herbievine/pen/YzwNewQ
client.on('message', message=>{
let args
if (message.startsWith('?'))
args = message.content.replace('?', '').split(' ')
if (args[0].toLowerCase() === 'ann') {
const embed = new Discord.MessageEmbed()
.addField('test', message.contentreplace('?ann', ''));
message.channel.send(embed);
}
}
})
Hope it helps

message.content represents the whole message that you are sending, so in this case will be ?Ann Hello Guys.
DiscordJS doesn't understand what commands are, and it doesn't split this stuff out for you.
As your message is formatted as ?Mention <Command arguments here> you can split it via the space within the string.
let messageContent = message.content.split(" ")
This takes your string of "?Ann Hello Guys" and turns it into "?Ann", "Hello", "Guys"
.split(" ") separates your string via the spaces, and returns an array.
You can then do messageContent.pop() to remove the first element in the array, which is "?Ann".
You can then .join(" ") these back together, forming the string "Hello Guys" and send that. Fully formed code:
let splitMessage = message.content.split(" ")
splitMessage.pop();
const transformedMessage = splitMessage.join(" ")
