Question

length to validate a user input field . it works fine on the first attempt but if i go back and change the field it doesn’t update .

$("#user").blur(function () {
if ($("#user").val().length < 3) {
    $("#userval").addClass("valincorrect").html($("#user").val().length);

} else {
    $("#userval").addClass("valcorrect");
};
});

Answer 1

forgot to remove the old class

$("#user").blur(function () {
    if ($("#user").val().length < 3) {
        $("#userval").removeClass("valcorrect").addClass("valincorrect").html($("#user").val().length);
    }
    else {
        $("#userval").removeClass("valincorrect").addClass("valcorrect");
    };
});
