问题 I have an HTML input box <input type="text" id="foo" value="bar"> I've attached a handler for the ' keyup ' event, but if I retrieve the current value of the input box during the event handler, I get the value as it was, and not as it will be!

问题 Note: as far as i know that closest() method searches up the DOM tree for the closest element which matches a specified CSS selector.
