Are you looking for jQuery form validation plugin? If yes then here I am going to share simple Light-weight, Mobile-ready and Customizable Form Validation Plugin for jQuery. Checkify is a jQuery based form validation plugin that provides realtime, client-side, mobile-friendly validation feature for input fields. The plugin highligihts the invalid form fields and displays custom error messages as popup tooltip.



Include bootstrap and jQuery library after that load plugins js+css library.

<link rel="stylesheet" href="" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
    <link rel="stylesheet" href="checkify.css" />
<!-- Js -->
 <script src="" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script>
<script src="checkify.min.js"></script>


Create simple HTML form which need to validate before submit.

<form id="my-form">
            <div class="form-group">
                <div class="row">
                    <div class="col-sm-3">
                        <input type="text" class="form-control" data-checkify="minlen=2,required" />
                    <div class="col-sm-3">
                        <input type="text" class="form-control" data-checkify="maxlen=4,number" />
                    <div class="col-sm-3">
                        <input type="text" class="form-control" data-checkify="number" />
                    <div class="col-sm-3">
                        <textarea class="form-control" data-checkify="maxlen=5"></textarea>
            <button class="my-button">click me</button>


Call the plugin and apply realtime client side form validation.

            message: {
                hGap: 15
            button: '.my-button',
            realTime: true,
            onError: function () {
            onValid: function (e, x) {
                console.log(e, x);
