Jquery: Form validation not working

javascript, jquery, validation

Solution

You have 2 elements with the `id="form"`, so the validator is assigned to the `div` not to the `form`.

Change the `id` value of the `div` to something else.

Also the `additional-methods.js` file must be added after `query.validate.js` and there is a syntax error because of the `alert()` within the `validate` so

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
<script src="http://ajax.microsoft.com/ajax/jquery.validate/1.11.1/additional-methods.js"></script>
<div>
    <center>
        <form id="form">
            <div class="col-xs-12">
                <input type="text" name="name" id="name" placeholder="Name" required />
            </div>
            <div class="col-xs-12">
                <input type="text" name="nric" id="nric" placeholder="NRIC" required />
            </div>
            <div class="col-xs-12">
                <select class="dropdown" id="gender" onChange="changeColor(this)">
                    <option value="" disabled selected>Gender</option>
                    <option value="female">Female</option>
                    <option value="male">Male</option>
                </select>
            </div>
            <div class="col-xs-12">
                <input type="text" name="mobile" id="mobile" placeholder="Mobile" required />
            </div>
            <div class="col-xs-12">
                <input type="text" name="address" id="address" placeholder="Address" required />
            </div>
            <div class="col-xs-12">
                <input type="email" name="email" id="email" placeholder="Email" required />
            </div>
            <input id="submit" class="button" type="submit" value="submit"/>
        </form>
    </center>
</div>

then

jQuery(function ($) {
    $('#form').validate({
        rules: {
            name: {
                required: true,
                minlength: 2,
                maxlength: 20,
                lettersonly: true
            },
            ssn: {
                required: true,
                minlength: 9,
                maxlength: 9,
                nowhitespace: true
            },
            gender: {
                required: true
            },
            mobile: {
                required: true,
                minlength: 10,
                maxlength: 13,
                digits: true
            },
            address: {
                required: true,
                minlength: 10,
            },
            email: {
                required: true,
                minlength: 6,
                email: true
            }
        },
        messages: {
            name: {
                required: "Please enter your name",
                minlength: "Name should be more than 2 characters",
                maxlength: "Name should be less than 20 characters",
                lettersonly: "Name should contain only letters"
            },
            ssn: {
                required: "Please enter your NRIC",
                minlength: "NRIC should be more than 9 characters",
                maxlength: "NRIC should be less than 9 characters",
                nowhitespace: "NRIC should not have any spaces"
            },
            gender: {
                required: "Please select your gender",
            },
            mobile: {
                required: "Please enter your mobile number",
                minlength: "Mobile number should be more than 10 characters",
                maxlength: "Mobile number should be less than 13 characters",
                digits: "Mobile number should contain only digits"
            },
            address: {
                required: "Please enter your address",
                minlength: "Address should be more than 10 characters",
            },
            email: {
                required: "Please enter your email address",
                minlength: "Password should be more than 6 characters",
                email: "Please enter a valid email address"
            }
        },
    });
});
