JavaScript忽略大小写

Question

quick question here. Im writing a discord bot in discord.js, which uses javascript. Here is a snippet of my current code:

if (message.content.includes("hello")){ message.react("👍")}

This, however, only returns the react if it is in that exact case, not if it is Hello, HELLO or helLO. How could i change the code so it accepts all variations?

Many thanks for any answers

Answer 1

You may use following snippet to find case insensitive matches.

 let message = "Okay google Chrome say Hello"; let regex = new RegExp("hello","gi"); if(message.match(regex)){ //react console.log("Reacting"); }else{ console.log("Not reacting"); } 

Answer 2

You to can convert one side or both into lower or uppercase and then compare.

var message = "Hello World";
if(message.toLowerCase().includes("hello".toLowerCase()){
 message.react("👍")
}
