jquery.validation - how to ignore default values when validating mandatory fields

Question

I am using jquery validation plugin to validate a registration form.

Each text input field has instructions pre-filled as values in the input box

ex: for a text-input box id='Name', the default value will be set to 'Enter Your Name'. I have pasted below sample code:

<input type="text" id="Name" value="Enter Your Name" onfocus="if(this.value == 'Your Name'){this.value = '';}" type="text" class="required" onblur="if(this.value == ''){this.value='Your Name';}" size="25" />

What I need to know is how to specify in the validation rule such that the plugin throws a required field error if the input box contains either the default message or empty values.

Help much appreciated.

I think this is better:

jQuery.validator.addMethod("defaultInvalid", function(value, element) 
{
    return !(element.value == element.defaultValue);
});
