jQuery validate - how do I ignore letter case?

Question

Probably a goofy question, but I can\'t seem to find anything in google land. I simply need one of my methods to ignore the case of the entered field. I am doing a city name mat

You could even create a more generic jQuery validation rule which can be reused to perform a case insensitive comparison like

$.validator.addMethod("equalToIgnoreCase", function (value, element, param) {
        return this.optional(element) || 
             (value.toLowerCase() == $(param).val().toLowerCase());
});

which can then be used for the following two sample inputs

like

$("form").validate({
    rules: {
        firstname: {
           equalToIgnoreCase: "input[name=username]"
        }
    },
    messages: {
        firstname: {
           equalToIgnoreCase: "The 'firstname' must match the 'username'"
        }
    });
