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");
};
});
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");
};
});
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.
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.
