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

$("#ParentAdNumber").rules("remove", "required");

From the documentation: http://docs.jquery.com/Plugins/Validation/rules

Edit: messages

Adding:

$("#ParentAdNumber").rules("add", {
    optionName: true,
    messages: {
        optionName: "message for optionName"
    }
});

Removing:

$("#ParentAdNumber").rules("remove", "messages");

Looking at the source code of Validation, it doesn't look like you can remove specific messages...

Answer 2

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);

Answer 3

This should do it....

.rules("add", {required: true, messages: {required: "Required input")}
