This is my code: // Type inside this function function isValidHex(text) {
let hexRegEx = /^#[0-9 A-F]{6}$/i.test(text); return hexRegEx;
}
when I preview this everything is working as it should, the background turns green etc.
Why I get this error message when I press the button "Check Work"?
Thank you
// Type inside this function
function isValidHex(text) {
let hexRegEx = /^#[0-9 A-F]{6}$/i.test(text);
return hexRegEx;
}
const hex = document.getElementById("hex");
const body = document.getElementsByTagName("body")[0];
hex.addEventListener("input", e => {
const text = e.target.value;
const valid = isValidHex(text);
if (valid) {
body.style.backgroundColor = "rgb(176, 208, 168)";
} else {
body.style.backgroundColor = "rgb(189, 86, 86)";
}
});

so if you just make sure that the variable is let hexRegEx = /^#[0-9 A-F]{6}$/i
you can then return hexRegEx.test(text)
and it works the same, but it will also pass the challenge.
