Palindrome Checker

JavaScript
1

Error code:

When you click on the #check-btn element without entering a value into the #text-input element, an alert should appear with the text Please input a value

My code so far:

const palInputCheck = input => {
const inputOriginal = input;
if (inputOriginal === “”) {
alert(“Please input a value”);
return;
}

I’m still getting this error, I have my js script linked in HTML. Am I using the alert wrong?

Thanks!

I’m not sure since you haven’t shared the rest of your code, but I also fed the alert text into the result of the page.

const palInputCheck = () => {
const inputOriginal = input;
if (inputOriginal === “”) {
alert(“Please input a value”);
return;
}

const lower = input.replace(/[^A-Za-z0-9]/gi, “”).toLowerCase();
let resultPal = “${inputOriginal}”
{lower === […lower].reverse().join(“”) ? “is” : “is not”}
" a palindrome.";

check.addEventListener(“click”, palInputCheck);
result.div.remove(“hidden”);

};

It’s supposed to pull up a window, right?

Imma rewrite it without the arrow function, see if that does anything.

I don’t see that you have defined the variable “input”.
