jquery - How to add messages to a class with addClassRules

Question

I'm using jQuery Validate to validate a page with a large number of repeated rows of data. Due to limited space, each row has it's own validation summary.

I use addClassRules to apply the validation rules to the page but the default error messages are too generic in the summary (e.g. "Field is required, Field is required etc).

Example:

jQuery.validator.addClassRules({
amount: {
    required: true,
    range: [0, 2000000]
},
comment: {
    maxlength: 51
},
owner: {
    notFirstOption: true
},
A: {
    required: function (element) {  
        return getParentElement($(element), "tr").find(".colB input.B").val().length > 0;
    },
    digits: true
}});

Can you apply custom messages for the rules in each validation class? Ideally I'm after something like:

jQuery.validator.addClassMessages({
    amount: {
        required: "Amount is required",
        range: "Amount must be between 0 and 2,000,000"
    },
    comment: {
        maxlength: "Comment may be a maximum of 51 characters"
    },
    owner: {
        notFirstOption: "Please select an owner"
    },
    A: {
        required: "A is required if B is entered",
        digits: "A must be numeric"
    }});

Thanks in advance for any help you can offer!

Answer 1

In the documentation, the answer is to alias the method that you want to call and add the custom message.

Check the reference under the "Refactoring rules" heading:

// alias required to cRequired with new message
$.validator.addMethod("cRequired", $.validator.methods.required,
"Customer name required");
// alias minlength, too
$.validator.addMethod("cMinlength", $.validator.methods.minlength, 
// leverage parameter replacement for minlength, {0} gets replaced with 2
$.format("Customer name must have at least {0} characters"));
// combine them both, including the parameter for minlength
$.validator.addClassRules("customer", { cRequired: true, cMinlength: 2 });
