jQuery Validation Plugin – Dynamically change validator message

Please read Guu’s comment below for a far better solution to this problem!

I’ve been using the jQuery Validation Plugin and needed to change a validation message dynamically based on the user input. I had a quick search but couldn’t find an easy solution. Unfortunately the messages are not changeable after the initial construction of the validator object. I managed to get around the problem by removing the validator an then re-adding with a new message:

Create validator

    rules: {
        EnquiryText: { required: true }
    messages: {
        EnquiryText: "Enquiry must contain an entry."

Dynamically change message

function setEnquiryValidationTo(message) {
    $("#EnquiryText").rules("add", {
        required: true,
        messages: {
            required: message

There may be a better/easier way to do this but I couldn’t find one via Google.
