Question

How can I allow only gmail.com as domain in my email field validating using jquery-validation plugin ?

$(\"#myForm\").validate({
rules: {
    myemail: {

Take the Gmail regex from this answer and use it within the addMethod method to create a new custom rule called "gmail"...

jQuery.validator.addMethod('gmail', function (value, element) {
    return this.optional(element) || /^[a-z0-9](\.?[a-z0-9]){5,}@gmail\.com$/i.test(value);
}, "not a valid Gmail email address");

$("#myForm").validate({
    rules: {
        myemail: {
            required: true,
            gmail: true
        }
    }
});

It does not matter if you call .validate() before or after the .addMethod() method.
