为什么说.setDescription不是函数？ （RichEmbed in JavaScript）

Question

I'm creating an embed for my command /quotes which is to be used for my discord bot.

Here's the code:

if(cmd === `${prefix}quotes`){

  quotes = new Discord.RichEmbed();
  q1 = "  -- Andres Iniesta";
  q2 = "  -- French Poverb";
  q3 = "  -- www.quotesgate.com"

  .setDescription("**__Here are some inspirational quotes!__**")
  .setColor("#319786")
  .addField("**Some people like you, some people don't. In the end, you just have to be yourself.**". q1)
  .addField("**Wherever life plants you, bloom with grace**", q2)
  .addField("Don’t forget you’re human. It’s okay to have a meltdown. Just don’t unpack and live there. Cry it out. Then refocus on where you’re headed", q3)

  return message.channel.send(quotes);
}

I keep receiving an error on my console that .setDescription is not a function

Answer 1

The problem is that you don't have a semicolon after the line q3 = " -- www.quotesgate.com" so it pastes the next line right after it. So it basically becomes

q3 = "  -- www.quotesgate.com".setDescription("**__Here are some inspirational quotes!__**")

which won't work ofcourse. I'm assuming you want to call the setDescription and addField on the embed so you need to change your code to the following:

if(cmd === `${prefix}quotes`){

  q1 = "  -- Andres Iniesta";
  q2 = "  -- French Poverb";
  q3 = "  -- www.quotesgate.com";

  quotes = new Discord.RichEmbed()
    .setDescription("**__Here are some inspirational quotes!__**")
    .setColor("#319786")
    .addField("**Some people like you, some people don't. In the end, you just have to be yourself.**". q1)
    .addField("**Wherever life plants you, bloom with grace**", q2)
    .addField("Don’t forget you’re human. It’s okay to have a meltdown. Just don’t unpack and live there. Cry it out. Then refocus on where you’re headed", q3);

  return message.channel.send(quotes);
}

Answer 2

if(cmd === `${prefix}quotes`){

  quotes = new Discord.RichEmbed();
  q1 = "  -- Andres Iniesta";
  q2 = "  -- French Poverb";
  q3 = "  -- www.quotesgate.com";

  quotes.setDescription("**__Here are some inspirational quotes!__**");
  quotes.setColor("#319786");
  quotes.addField("**Some people like you, some people don't. In the end, you just have to be yourself.**". q1);
  quotes.addField("**Wherever life plants you, bloom with grace**", q2);
  quotes.addField("Don’t forget you’re human. It’s okay to have a meltdown. Just don’t unpack and live there. Cry it out. Then refocus on where you’re headed", q3);

  return message.channel.send(quotes);

}

Done! :-)
