jquery required field validator on click of anchor

I want to validate textbox on click of anchor with jquery required field valid开发者_开发问答ator http://docs.jquery.com/Plugins/Validation Can you let me know how can I do that?

Bind a event to the click of this anchor with this:

$("#field_id_you_want_to_validate").validate({
  rules: {
    required: true
  }
})

Let say you have anchor with id "myAnchor". This is how i write the code

$("#myAnchor").click(function(){
// Validate the Textbox that you want 

$("#textboxid").attr('class', 'required');

});
