Web Development Techdegree Student 13,802 PointsUsing the test() method to find valid Hexs, RegEx Code challenge 2/2
A bit confused, also tried setting a variable to house the test method in but that didn't work either, any suggestions would be greatly appreciated! thanks
// Type inside this function
function isValidHex(text) {
const hexRegEx = /^#[\da-f]{6}$/i;
isValidHex.test(text)
return isValidHex;
}
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)";
}
});

return hexRegEx.test(text);
