How about this?

If you just want not to allow unnecessary characters then you can just do the following:

var validformat=/^\d{2}\/\d{2}\/\d{4}$/ //Basic check for format validity
if (!validformat.test(input.value)) {
    alert("Invalid Date Format. Please correct and submit again.")
    return false;
}
