adding jquery validation dynamically

Question

I found where you can add jquery validation rules dynamically like this:

$(\"#ParentAdNumber\").rules(\"add\", { required: true });

But how

Answer 1

Simple!

$("#ParentAdNumber").rules("add", {
    required: true,
    messages: {
        required: "Required input"
    }
});

you can change the message storing the rule:

var objRule = $("#ParentAdNumber").rules();

Changing:

objRule.messages.required = "New message";

and Re-applying:

$("#ParentAdNumber").rules("add", objRule);
