Still not right! I need to see the right regex please!
// Type inside this function
function isValidHex(text) {
const hexRegEx = /^(#)[d\a-f]{6}$/i
}
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)";
}
});

44,806 PointsYou have const hexRegEx = /^(#)[d\a-f]{6}$/i
and not const hexRegEx = /^(#)[\da-f]{6}$/i
. The \
needs to be before the d
to specify that it can be any digit. If you don't want to use \d
, you could use 0-9
. You also don't need to have parentheses around the #.
