After the initial iteration, the .length function ceases to function properly when

A validation method is set up to check the length of a user input field. It functions properly on the initial try, but does not update if I go back and modify the field.

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

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

Answer №1

Oops, neglected to delete the previous class

$("#user").blur(function () {
    if ($("#user").val().length < 3) {
        $("#userval").removeClass("valid-correct").addClass("valid-incorrect").html($("#user").val().length);
    }
    else {
        $("#userval").removeClass("valid-incorrect").addClass("valid-correct");
    };
});

Answer №2

For optimal functionality, consider removing the 'valincorrect' class when a value is marked as correct and vice versa for 'valcorrect'. Simplify by using only one class and utilizing .toggleClass() instead.

Answer №3

I encountered difficulties when attempting to compare the length using dom.

For a solution, you can check out this example: http://jsfiddle.net/FccPH/1/

It is also advisable to store characters if you plan on reusing them later.
