How to validate input, in non-form element, on keyup with jQuery validate plugin

I have a site that is being built in ASPX. Unfortunately, because of this fact, I cannot actually use the <form> tag to wrap my inputs, and as far as I can see, jQuery Validation Plugin only supports validating inputs within a <form>. Is there any way to validate these inputs, using the specified rules, on keyup without having them wrapped in a <form> tag?

Unique ID that gets a date in specific format?

I have code that will generate a random unique id.. but is there a way I can edit this code so that it grabs a date in a specific way like yyyy-mm-dd-0001. the last 4 digits I want it to add 1 each time the generateid button is clicked. so it will change to 0002. Here is the current code I have. Is there a function that can grab the date automatically?
