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

Answer 1

Nick's answer fits the bill. I needed to compare two fields on the form and make sure they were not equal. I modified it just a bit.

jQuery.validator.addMethod("notEqual", function(value, element, param) {
 return this.optional(element) || value != $(param).val();
}, "This has to be different...");

$("#cform").validate(
{
    rules: {
        referringsales: { required: false, notEqual: "#salesperson" }
    }
});

Edited to answer comment:

If you have more than one set of dropdowns to compare, the method also works with that case.

jQuery.validator.addMethod("notEqual", function(value, element, param) {
 return this.optional(element) || value != $(param).val();
}, "This has to be different...");

$("#cform").validate(
{
    rules: {
        referringsales: { required: false, notEqual: "#salesperson" }
        DropDown2: { required: false, notEqual: "#SecondBase" }
    }
});

If the question is regarding comparing referringsales against 2 different bases (say #initialContact and #salesperson), then simply add that rule to the list.

referringsales: { required: false, notEqual: "#salesperson", notEqual: "#initialContact" }
