7,406 PointsSimplify the code, but not work
Hi team, when I simplify the code like the following codes. I find it works when having field value, but not works when no field value. But there is no any error msg. May I know why I can not simplify the code like this? Why have to have fieldTest? Thanks!
function isFieldEmpty() {
const field = document.querySelector('#info');
if (field.value === "") {
alert("Please provide your info.");
}

The main problem here is that the function is not returning any value.
