The Challenge says:
"Your regular expression matches CSS hexadecimal color values, but also matches other values. See if you can limit your regex to meet the requirements."
I am not sure of the extra values being allowed, 0-9 and A-F. I only am shown results when expected 7 chars are typed. Any thoughts?
// Type inside this function
function isValidHex(text) {
var hexRegEx = /\#[A-F0-9]{6}/i; //new RegExp
return hexRegEx.test(text);
}
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)";
}
});

Treehouse Moderator 37,799 PointsNice job Robert figuring it out. I just got your code to pass just adding a $ to the end to only allow 7 characters total. Without that the screen would stay green after entering more than 7 characters.
