How to change class of valid form field - jQuery form validation plugin

Tags: jquery,css,jquery-validate

Problem :

I am using bassistance jQuery form validation plugin.

I made a form with form fields and set rules;


$(document).ready(function() {
        submitHandler: function() {
    var validator = $("#testform").validate({
        rules: {
            field1: "required",
        messages: {
            field1: "",
        error: function(element) {
        success: function(label) {


#testform input{
  border: solid 2px black;
#testform input.error{
  border: solid 2px #CC0000;
#testform input.checked{
  border: solid 2px #094AB2;


<form id="testform" name="testform">
<input id="field1" name="field1" type="text" value="">
<input id="field2" name="field2" type="text" value="">
<input type="submit" value="submit"/>

The error function is working alright. But the success function is not adding styles to input type=text, instead, default style appears (black border instead of blue). How can I solve this?

Here is the working fiddle

Solution :

Change your #testform input.checked to #testform input.valid. I got this by submitting the form and check the class with developer tools or firebug. I saw the class name changed to valid and not checked
