Answer 2

Hi Alina Zeiler,
This can be done like Rishi Anand mentioned.
Grab the inserted value of the textarea and validate the input with certain words of/or whole strings.
Match() the inserted values with an if statement via regex to reply with an answer.

function send() {
// Grab to inserted value of input
inputvalue = document.getElementById("chatbotinput").value;
// Output the insert value to another textarea/box
outputvalue = document.getElementById("output").innerHTML = (inputvalue);

// If user inserted these word(s) then answer polite
if (/hey|hallo|bonjour|hi|hoi|hello/ig.test(inputvalue)) {
// If inserted value equals the match, answer to user
document.getElementById("output").innerHTML = ("Good afternoon!");
} else {
document.getElementById("output").innerHTML = ("Nothing to match!");
}
