How to add a Not Equal To rule in jQuery.validation

Question

I was wondering how to make it so that I could make a rule where a field is not equal to a value. Like I have a field called 'name' so I don't want 'name' = 'Your Name.'

Does anybody have an idea of how to do this? thanks for any help.

You could use a custom method, something like this:

jQuery.validator.addMethod("notEqual", function(value, element, param) {
  return this.optional(element) || value != param;
}, "Please specify a different (non-default) value");

Then use it like this:

$("form").validate({
  rules: {
    nameField: { notEqual: "Your Name" }
  }
});

Adding it as a rule like this makes it more extensible, so you can use it to compare against the default value in other fields.
